Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object to cool it continuously.

Nozzles that are angled 30° from the horizontal are standard. Although 45° nozzle angles achieve longer distances from a ballistics perspective, 45° nozzles have been observed to create large craters. In addition, a high amount of sand flows back towards the dredger. 30° nozzles instead project the sand with a flatter trajectory, minimizing back flow while achieving a final distance comparable to that reached by a 45° nozzle.

At its simplest, a balancing lake can be constructed by creating a dam across a drain or stream at a convenient valley, with a restricted diameter outlet pipe through the dam. Normal flows are carried happily through the pipe, but heavy flows back up and the water behind the dam is choked back. Over the following few days, the level subsides. This is often enough for a small housing development.

The previous course of the creek is still visible above the bridge. Water flows back on itself at bends and wide spots, creating swirling eddies along the banks. As the creek flowed around Rainbow Bridge fin, these abrasive eddies formed on both the upstream and downstream sides and cut circular alcoves in the rock wall. The sediment in the creek eventually scoured the softer layers of sandstone away, leaving the harder layers behind.

This difference in pressure causes sea breezes to blow from the ocean to the land, bringing moist air inland. This moist air rises to a higher altitude over land and then it flows back toward the ocean (thus completing the cycle). However, when the air rises, and while it is still over the land, the air cools. This decreases the air's ability to hold water, and this causes precipitation over the land.

A large area of streams, lakes, forestry and farming comprising the village and several hamlets situated some north of Bourges at the junction of the D12, D58 and the D30 roads. The river Rère has its source near the hamlet of Sommerère in the southeastern part of the commune. It flows northwest through the middle of the commune, enters the territory of Ménétréol-sur-Sauldre and flows back southwest in the northwestern part of Presly.

The area between each disk is effectively an individual grinding chamber, and the grinding medium is set in motion by the rotation of the disks, which accelerate the medium toward the shell. This action is most pronounced close to the disks. The medium flows back toward the shaft in the zone near the midpoint between the disks, creating a circulation of the grinding medium between each pair of disks, as shown in Figure 4. Figure 4.

Method implementation In Prograph a method is represented by a series of icons, each icon containing an instructions (or group of them). Within each method the flow of data is represented by lines in a directed graph. Data flows in the top of the diagram, passes through various instructions, and eventually flows back out the bottom (if there is any output). Several features of the Prograph system are evident in this picture of a database sorting operation.

The overflow from these spring-fed lakes flows back toward the mountain range and thus is named Reversed Creek. Reversed Creek reaches a confluence with Rush Creek and flows through Silver Lake and Grant Lake, completing the "loop" to the Mono Basin. Perched Boulder One notable geologic feature is the perched boulder, a glacial erratic next to the June Lake Fire Station. This boulder, a well-known landmark of the area, is 18 feet tall and weighs 150 tons.

The kaingineros were among the first reported settlers in this part of Laguna around the 17th century. Around mid-1800, this area was called barrio "Pauli" and was part of the town of Nagcarlan. Residents from this place used to say that the barrio "Pauli" got its name from the way that its brook flows at the edge of the settlement, whose stream flows back and forth. “Pauli,” must have come from the Tagalog word “Pauli-uli,” which means coming back and forth.

The topography includes a hilly region towards the west of the zone. The region receives rather heavy rainfall regularly during the months of August through November and in order to ensure proper drainage of the area, CIDCO has constructed holding ponds in the area to allow water to accumulate during high tide and heavy downpour. During low tide, water from the holding ponds flows back into the sea. The zone is characterised by loose soil with lowbearing capacity, and black stiff clay.

In most cases, with very efficient heat transport through the gas, it is very challenging to maintain such significant temperature differences between the gas and the condensing surface. Moreover, this temperature differences of course corresponds to a large effective thermal resistance by itself. The bottleneck is often less severe at the heat source, as the gas densities are higher there, corresponding to higher maximum heat fluxes. The condensed working fluid then flows back to the hot end of the pipe.

According to old maps, the source of the creek was near Nereid and Hill Avenues in the Bronx's Edenwald neighborhood, where it flows southwest, then turns southeast near East 233rd Street. It then flows above ground at Seton Falls Park, entering a man-made waterfall. After exiting the park, it flows back underground. South of Boston Road, the creek flowed into a man-made pond called Holler's Pond, located at the site of the Boston Secor Houses in the Baychester neighborhood.

There's no need for it to retransmit that packet. However, it also updates its batch map about the progress of the packets in the batch. In this way, the information about the progress of the packets flows backward toward the source as radios farther from the destination update their batch maps by eavesdropping on retransmissions. Since the retransmissions closer to the source radio occur later, the packet progress information flows back to the source radio, even though no acknowledge packets are ever transmitted.

Less than half of injected water is recovered as flowback or later production brine, and in many cases recovery is <30%. As the fracturing fluid flows back through the well, it consists of spent fluids and may contain dissolved constituents such as minerals and brine waters. In some cases, depending on the geology of the formation, it may contain uranium, radium, radon and thorium. Estimates of the amount of injected fluid returning to the surface range from 15-20% to 30–70%.

After around it turns south for eight miles (13 km) and then flows back to the southwest for approximately 10 miles. Near Shoigabli it turns due south for about where it passes Mount Finley and turns more westerly and flows generally southwest for another 9 miles. Between Zoblum and Alfabli the Saint John widens and flows to the northwest for around before heading west for a mile to Hartford. The river then dives to the southwest for its final 6.5 miles.

This has three cusps which are not attached to any papillary muscles. When the ventricle relaxes blood flows back into the ventricle from the artery and this flow of blood fills the pocket-like valve, pressing against the cusps which close to seal the valve. The semilunar aortic valve is at the base of the aorta and also is not attached to papillary muscles. This too has three cusps which close with the pressure of the blood flowing back from the aorta.

Gentle Glacier () is a small glacier lobe, to the east and immediately below Forecastle Summit, which drains south into deglaciated Barnacle Valley in the Convoy Range of Victoria Land, Antarctica. Though a part of the Northwind Glacier – Fry Glacier system, this diminished glacier flows back into Barnacle Valley. The name was proposed by New Zealand geologist Christopher J. Burgess and describes the glacier, but also the excellent helicopter support provided to his 1976–77 field party by U.S. Navy helicopters, "Gentle" being their code name.

The RRDE takes advantage of the laminar flow created during rotation. As the system is rotated, the solution in contact with the electrode is driven to its side, similar to the situation of a rotating disk electrode. As the solution flows to the side, it crosses the ring electrode and flows back into the bulk solution. If the flow in the solution is laminar, the solution is brought in contact with the disk and with the ring quickly afterward, in a very controlled manner.

Ventricular relaxation, or diastole, follows repolarization of the ventricles and is represented by the T wave of the ECG. It too is divided into two distinct phases and lasts approximately 430 ms. During the early phase of ventricular diastole, as the ventricular muscle relaxes, pressure on the remaining blood within the ventricle begins to fall. When pressure within the ventricles drops below pressure in both the pulmonary trunk and aorta, blood flows back toward the heart, producing the dicrotic notch (small dip) seen in blood pressure tracings.

Left axis deviation can be a sign of advanced disease. Echocardiogram can be helpful in determining the root cause of the disease, as it will clearly show aortic root dilation or dissection if it exists. Typically the pump function of the heart during systole is normal, but echocardiogram will show flow reversal during diastole. This disease is classified using regurgitant fraction (RF), or the amount of volume that flows back through the valve divided by the total forward flow through the valve during systole.

When the magnetic field is completely dissipated the current will stop and the charge will again be stored in the capacitor, with the opposite polarity as before. Then the cycle will begin again, with the current flowing in the opposite direction through the inductor. The charge flows back and forth between the plates of the capacitor, through the inductor. The energy oscillates back and forth between the capacitor and the inductor until (if not replenished from an external circuit) internal resistance makes the oscillations die out.

The Kakisa River originates in northern Alberta, immediately south of the Northwest Territories border, from Creighton Lake, at an elevation of . It flows westwards, briefly crossing into the Northwest Territories, then back into Alberta. east of the British Columbia border it turns north and flows back in the Northwest Territories. It keeps a north to northeast direction, paralleling the Redknife River for a while, then turns east, where it builds a complex lake and channel system before it empties into the Tathlina Lake at its western extremity.

Mitral regurgitation Mitral regurgitation (MR) occurs when the mitral valve fails to close completely, causing blood to flow back into the left atrium during ventricular systole. The constant backflow of blood through the leaky mitral valve implies that there is no true phase of isovolumic contraction. Since the afterload imposed on the ventricle is reduced, end-systolic volume can be smaller than normal. There is also no true period of isovolumic relaxation because some LV blood flows back into the left atrium through the leaky mitral valve.

This allows one to use the largest nonlinear coefficient of the material in the nonlinear interaction. Quasi-phase-matching ensures that there is positive energy flow from the pump frequency to signal and idler frequencies even though all the frequencies involved are not phase locked with each other. Energy will always flow from pump to signal as long as the phase between the two optical waves is less than 180 degrees. Beyond 180 degrees, energy flows back from the signal to the pump frequencies.

After Priboj it turns north-west and enters Bosnia and Herzegovina, but only for a few kilometers when it flows back to Serbia and then again to Bosnia at Rudo. In Bosnia and Herzegovina, Lim flows between the mountains of Bić, Javorje and Vučevica from the south, and the Varda mountain from the north, before it empties into the Drina near the village of Međeđa. The lowest section of the river is flooded by the Višegrad Reservoir, created by the Višegrad hydroelectrical power plant on the Drina.

Washington: GPO. p. 169. This pattern has to be applied at a particular stock consistency; otherwise the pattern will be lost as the fiber flows back while the stock moves past the dandy (too wet), or fiber will pick out of the stock (too dry), causing surface disruption. As the fiber is displaced, localized areas of higher and lower density are produced in a laid pattern, and the pattern is also created on the paper's surface. The pattern is therefore apparent both as one looks through the sheet and as one views its surface.

As it flows back through the stages the water is now called brine, to distinguish it from the inlet water. In each stage, as the brine enters, its temperature is above the boiling point at the pressure of the stage, and a small fraction of the brine water boils ("flashes") to steam thereby reducing the temperature until an equilibrium is reached. The resulting steam is a little hotter than the feed water in the heat exchanger. The steam cools and condenses against the heat exchanger tubes, thereby heating the feed water as described earlier.

Up-valley winds during the day and down-valley winds at night. Valley winds are best developed on clear summer days and are driven by horizontal pressure gradients. During the day, the valley is warmer than the flat terrain (because it contains a smaller volume of air receiving the same amount of radiation), which creates a lower pressure zone over the valley, entraining the air from the plains up to the valley. The opposite process occurs at nighttime, where the valley cools faster and the air flows back down to the plains .

The Cambodian hydro- logical system is dominated by the Mekong River and Tonle Sap Great Lake. From July to the end of October, when the level of the Mekong is high, water flows via the Tonle Sap River, increasing the size of the lake from 2,600 km2 to about at its maximum extent. The storage capacity of Tonle Sap Great Lake is about . When the level of the Mekong decreases, the Tonle Sap River reverses its flow and water flows back from the Tonle Sap Lake into the Mekong River.

The typical approach to describe dissipation is to split the total system in two parts: the quantum system where dissipation occurs, and a so- called environment or bath where the energy of the former will flow towards. The way both systems are coupled depends on the details of the microscopic model, and hence, the description of the bath. To include an irreversible flow of energy (i.e., to avoid Poincaré recurrences in which the energy eventually flows back to the system), requires that the bath contain an infinite number of degrees of freedom.

The East Branch Reservoir has a surface area of , reaches a mean depth of 32 feet (10 m), and holds at full capacity. It drains a 75-square mile (180 km²) area that includes Bog Brook Reservoir. Its water flows back into the East Branch of the Croton River south of the dam, then into The Diverting Reservoir, then via the Croton River to the Muscoot and the New Croton reservoirs, into the New Croton Aqueduct. Water from the aqueduct flows into the Jerome Park Reservoir in the Bronx for daily distribution.

Gravitational potential energy has a number of practical uses, notably the generation of pumped-storage hydroelectricity. For example, in Dinorwig, Wales, there are two lakes, one at a higher elevation than the other. At times when surplus electricity is not required (and so is comparatively cheap), water is pumped up to the higher lake, thus converting the electrical energy (running the pump) to gravitational potential energy. At times of peak demand for electricity, the water flows back down through electrical generator turbines, converting the potential energy into kinetic energy and then back into electricity.

Skookumchuck Narrows during a strong ebb tide Hurley Weir Kayakers playboating on Falls of Lora In kayaking, a playspot is a place where there are favorable stationary features on rivers, in particular standing waves (which may be breaking or partially breaking), 'holes' and 'stoppers', where water flows back on itself creating a retentive feature (these are often formed at the bottom of small drops or weirs), or eddy lines (the boundary between slow moving water at the rivers' edge, and faster water). Playspots exist both in natural and artificial whitewater.

Conversely, some of this "bank storage" flows back into the reservoir as springs and seeps when Lake Powell is low. Exactly how much of this water has potential to return to the reservoir, and how much "disappears" into the ground, is subject to debate. The Bureau of Reclamation projected that once Lake Powell filled, the total bank storage would stabilize at approximately , and henceforth would fluctuate depending on water levels in the reservoir. The actual loss was , twice the initial prediction, but river flow data indicates that further leakage after 1980 has been negligible.

The Meissner effect induces a screening current on the inner surface of the tube, flowing opposite to and being exactly as large as the sum of the currents inside the tube. Thus, this shielding current exactly cancels the magnetic field inside the tube produced by the currents in the wires. The screening current flows back across the outer surface of the tube, giving rise to a magnetic field in the room outside of the tube. This field is detected by a highly sensitive magnetometer, acting as a null detector.

Animation illustrating electrical resonance in a tuned circuit, consisting of a capacitor (C) and an inductor (L) connected together. Charge flows back and forth between the capacitor plates through the inductor. Energy oscillates back and forth between the capacitor's electric field () and the inductor's magnetic field (). Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedance of the circuit is at a minimum in a series circuit or at maximum in a parallel circuit (usually when the transfer function peaks in absolute value).

The Spray River is a tributary of the Bow River in western Alberta, Canada. The Spray River originates in the southern area of Banff National Park in the Canadian Rockies and flows through the Spray Valley Provincial Park and alongside the western border of the Bow Valley Wildland Provincial Park. The Spray Lakes Reservoir and the Goat Pond are formed along this section of the river, and the scenic Smith Dorrien Trail (part of the Kananaskis Trail system) runs along. The river then flows back into Banff National Park and north-west to Banff, where it merges into the Bow River.

The main function of the core shroud is to direct the current of water flow inside of the reactor pressure vessel. Cold water is pumped into the reactor pressure vessel from an outside water source. The cold water flows down in between the wall of the reactor pressure vessel and the outside wall of the core shroud where it meets the fuel assemblies. It is here that the cold water is heated, and the heated water flows back up the gap between the wall of the reactor pressure vessel and the outside wall of the core shroud.

This work is a substantial contribution to cardiac physiology, for it introduces into biology the doctrine of circulation of the blood in the seventeenth century. Opposed and obliging work heralding Harvey's discovery go back to the thirteenth century, when the pulmonary circulation and gas exchange was proposed by Ibn Al-Nafis. Both long since proven theories are incomplete when studied separately but together form core knowledge of present-day cardiology. In 1553, Michael Servetus said that blood flows from the heart to the lungs, and that it there mixes with air to form the arterial blood which flows back to the heart.

The water in lakes, rivers, and aquifers then either evaporates back to the atmosphere or eventually flows back to the ocean, completing a cycle. Water changes its state of being several times throughout this cycle. The areas of research within hydrology concern the movement of water between its various states, or within a given state, or simply quantifying the amounts in these states in a given region. Parts of hydrology concern developing methods for directly measuring these flows or amounts of water, while others concern modeling these processes either for scientific knowledge or for making a prediction in practical applications.

The octopus has three hearts, one main two-chambered heart charged with sending oxygenated blood to the body and two smaller branchial hearts, one next to each set of gills. The circulatory circuit sends oxygenated blood from the gills to the atrium of the systemic heart, then to its ventricle which pumps this blood to the rest of the body. Deoxygenated blood from the body goes to the branchial hearts which pump the blood across the gills to oxygenate it, and then the blood flows back to the systemic atrium for the process to begin again.Wells, M.J. (1980).

Direct current with a positively charged electrode (DCEP) is less common, and is used primarily for shallow welds since less heat is generated in the base material. Instead of flowing from the electrode to the base material, as in DCEN, electrons go the other direction, causing the electrode to reach very high temperatures. To help it maintain its shape and prevent softening, a larger electrode is often used. As the electrons flow toward the electrode, ionized shielding gas flows back toward the base material, cleaning the weld by removing oxides and other impurities and thereby improving its quality and appearance.

Northeast of Nashville, the river is dammed twice more, forming Cordell Hull Lake and Old Hickory Lake. After flowing through Nashville and picking up the Stones River, the river is dammed to form Cheatham Lake. The river turns northwest toward Clarksville, where it is joined by the Red River, and then flows back into Kentucky at the Land Between the Lakes National Recreation Area, a section of land nestled between Lake Barkley, which is fed by the Cumberland River, and Kentucky Lake. Finally, the river flows north and merges with the Ohio River at Smithland, northeast of Paducah.

Proximity of arteries and veins in the leg results in heat exchange, so that as the blood flows down it becomes cooler, and doesn't lose much heat to the snow. As the (cold) blood flows back up from the paws through the veins, it picks up heat from the blood flowing in the opposite direction, so that it returns to the torso in a warm state, allowing the fox to maintain a comfortable temperature, without losing it to the snow. This system is so efficient that the Arctic fox does not begin to shiver until the temperature drops to .

When the pump has raised water into the tray, briefly submerging the roots, the pump is rendered inactive using a switch, typically a timer, and the water flows back down the same tube. This eliminates the need for more than one sealed fitting and reduces overall complexity of the system. Ebb and flow systems come on according to the water- holding capacity of the medium in which the roots sit. Highly water-retentive media can require watering only once a day, while others require two to as many as six floodings, with each "flood" stage only lasting a few minutes.

Crocodilians were traditionally thought to breathe like mammals, with airflow moving in and out tidally, but studies published in 2010 and 2013 conclude that crocodilians breathe more like birds, with airflow moving in a unidirectional loop within the lungs. When a crocodilian inhales, air flows through the trachea and into two primary bronchi, or airways, which branch off into narrower secondary passageways. The air continues to move through these, then into even narrower tertiary airways, and then into other secondary airways which were bypassed the first time. The air then flows back into the primary airways and is exhaled.

Annual evaporation from reservoirs has been estimated at in Turkey, in Syria and in Iraq. Water quality in the Iraqi Euphrates is low because irrigation water tapped in Turkey and Syria flows back into the river, together with dissolved fertilizer chemicals used on the fields. The salinity of Euphrates water in Iraq has increased as a result of upstream dam construction, leading to lower suitability as drinking water. The many dams and irrigation schemes, and the associated large-scale water abstraction, have also had a detrimental effect on the ecologically already fragile Mesopotamian Marshes and on freshwater fish habitats in Iraq.

Urinary tract infections are more concerning in pregnancy due to the increased risk of kidney infections. During pregnancy, high progesterone levels elevate the risk of decreased muscle tone of the ureters and bladder, which leads to a greater likelihood of reflux, where urine flows back up the ureters and towards the kidneys. While pregnant women do not have an increased risk of asymptomatic bacteriuria, if bacteriuria is present they do have a 25–40% risk of a kidney infection. Thus if urine testing shows signs of an infection—even in the absence of symptoms—treatment is recommended.

The blockage, combined with several springs in the tunnel, creates an ideal micro-climate for the bats, which is maintained at around all year. When the temperature outside the tunnel is colder than this, cold air flows into the bottom of the tunnel where it is warmed by the water, and warmer air flows out along the top of the tunnel. During the summer the air flow is reversed, with warm air flowing into the top of the tunnel and being cooled as it flows back out over the water. By 2006, there were some 12,500 bats roosting in the tunnel, which included the largest known colony of Natterer's bat.

Foreground, a close-up of the bore evacuator on an M1A1 Abrams, while another tank fires in the background The evacuator is a passive device generally consisting of a ring of holes drilled into the barrel, surrounded by a cylindrical pressure reservoir that is sealed to the barrel's surface. When the gun is fired, high pressure gas generated by the burning propellant pushes the projectile forwards. When the projectile passes the holes drilled into the barrel the propellant gasses are free to flow into the reservoir. When the projectile leaves the gun the pressure in the barrel drops and the gas stored in the reservoir flows back into the barrel.

After crossing under Kipp Street, it bends eastward to cross under Quaker Road. A short channelized portion runs through the front yard of a large house on Quaker southeast of the intersection, after which the river flows back under Quaker and behind the houses on the west side into another impoundment, Chappaqua's Duck Pond. From its outlet it continues southeast between Quaker on its east and Douglas and Mill River roads on the west to the Saw Mill River Parkway. Just west of the Chappaqua train station, it turns southwest to parallel both the parkway and Metro-North Railroad's Harlem Line as both cross into the town of Mount Pleasant.

Here it passes half- concealed through industrial estates that have replaced traditional heavy industry, shadowed for a few kilometres by the Stourbridge Canal. It leaves the conurbation via the suburb of Wollaston, descending fairly rapidly from the West Midlands plateau to Prestwood. The Stour enters Staffordshire at Prestwood and veers southwards, henceforward shadowed by the Staffordshire and Worcestershire Canal, which crosses over it on a sandstone aqueduct just before its confluence with the Smestow Brook, an important tributary that drains the area north to Wolverhampton. The Stour flows south to Stourton and then loops along the eastern edge of the large village of Kinver, whence it flows back into Worcestershire.

The poem is spread over 20 pages, in various typefaces, amidst liberal amounts of blank space. Each pair of consecutive facing pages is to be read as a single panel; the text flows back and forth across the two pages, along irregular lines. The sentence that names the poem is split into three parts, printed in large capital letters on panels 1, 6, and 8. A second textual thread in smaller capitals apparently begins on the right side of panel 1, QUAND MÊME LANCÉ DANS DES CIRCONSTANCES ÉTERNELLES DU FOND D'UN NAUFRAGE ("Even when thrown into eternal circumstances from the bottom of a shipwreck").

Running from the west, the river Amper runs south of Dachau's old town, changes its direction at the former paper milling plant to the northeast and continues through Prittlbach into Hebertshausen. Coming from Karlsfeld, the Würm crosses Dachau-East and merges into the river Amper just outside the district limit of Hebertshausen. The Gröbenbach, which has its source south of Puchheim, runs through town coming from the south and merges into the Amper river at several locations near the festival grounds. The Mühlbach, a man made canal, is diverted from the river Amper at the electrical power plant and runs parallel and flows back into it after passing the paper mill.

As the gas flows back and forth through the regenerator, it periodically stores and takes up heat from the regenerator material. In contrast to the stack, the pores in the regenerator are much smaller than the thermal penetration depth, so the thermal contact between gas and material is very good. Ideally, the energy flow in the regenerator is zero, so the main energy flow in the loop is from the hot heat exchanger via the pulse tube and the bypass loop to the heat exchanger at the other side of the regenerator (main heat exchanger). The energy in the loop is transported via a travelling wave as in Fig.

Before the road branches off to Schwoich, the river is divided and a larger part is pumped under the hill t into a heat-only boiler station south of Kufsteins and acts as cooling water, before it flows back on a natural course into the Inn. Between Egerbach (a district of Schwoich) and (a district of Kufstein) the remaining part of the Weißache flows for about through a long gully, before it exits from the valley and heads northwest towards the Inn. This part discharges into the Inn around after the boiler station. In 2005 numerous measures were taken in Kufstein to reinforce the banks.

In 2011 The New York Times reported radium in wastewater from natural gas wells is released into Pennsylvania rivers, and compiled a map of these wells and their wastewater contamination levels, and stated that some EPA reports were never made public. The Times' reporting on the issue has come under some criticism. A 2012 study examining a number of hydraulic fracturing sites in Pennsylvania and Virginia by Pennsylvania State University, found that water that flows back from gas wells after hydraulic fracturing contains high levels of radium. Before 2011, flowback in Pennsylvania was processed by public wastewater plants, which were not equipped to remove radioactive material and were not required to test for it.

Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power may be greater than the real power. A negative power factor occurs when the device (which is normally the load) generates power, which then flows back towards the source. In an electric power system, a load with a low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment.

The river turns south into the township of Wilmot, takes in the left tributary Bamberg Creek and passes through the communities of Phillipsburg and New Hamburg, Ontario. The Nith continues south, takes in the left tributaries Baden Creek and Hunsburger Creek, enters into Blandford-Blenheim, Oxford County and reaches the community of Plattsville. The river turns east, takes in the right tributary Black Creek, and left tributaries Hiller Creek, Alder Creek and Eden Creek, passes back into Waterloo Region, and reaches the community of Ayr in the township of North Dumfries, where it takes in the left tributary Cedar Creek. It then turns sharply west, flows back into Oxford County, then turns southeast passing through the communities of Wolverton and Canning.

This also has the interesting side effect such that when the ride's pumps are switched off at the end of operation or in an emergency, the water naturally flows back to the end of the ride where it collects, leaving the majority of the ride's river channel empty and drained until the pumps are turned back on. All Intamin permanent (and most other) river rapids rides feature a connected lake of some sort at the end of the ride before the lift hill. This is sometimes used to store broken boats. Its main purpose, however, is to help store the large amounts of water that collect at the end of the ride (before the lift hill) once the ride's main pumps are turned off.

A Stirling cycle is like an Otto cycle, except that the adiabats are replaced by isotherms. It is also the same as an Ericsson cycle with the isobaric processes substituted for constant volume processes. # TOP and BOTTOM of the loop: a pair of quasi-parallel isothermal processes # LEFT and RIGHT sides of the loop: a pair of parallel isochoric processes Heat flows into the loop through the top isotherm and the left isochore, and some of this heat flows back out through the bottom isotherm and the right isochore, but most of the heat flow is through the pair of isotherms. This makes sense since all the work done by the cycle is done by the pair of isothermal processes, which are described by Q=W.

Engineer Derek Phillips was able to accomplish the task after a year of work, creating a water sculpture in which the water appears to flow up to the tops of four ramps arranged in a square, before cascading to the bottom of the next ramp. Called Wrong Garden, it was displayed at the Chelsea Flower Show in 2003. The illusion is accomplished with water containing air bubbles pumped through a chamber underneath the transparent glass ramps to a slit at the top from which the bulk of the water cascades down. This makes it appear that the water is flowing up, when really, a small amount of water diverted from the slit at the top flows back down the ramps in a thin layer.

This suggests that the southern Negev was arid to hyper-arid in these periods. During the Last Glacial Maximum (LGM) the Sahara desert was more extensive than it is now with the extent of the tropical forests being greatly reduced, and the lower temperatures reduced the strength of the Hadley Cell. This is a climate cell which causes rising tropical air of the Inter-Tropical Convergence Zone (ITCZ) to bring rain to the tropics, while dry descending air, at about 20 degrees north, flows back to the equator and brings desert conditions to this region. It is associated with high rates of wind-blown mineral dust, and these dust levels are found as expected in marine cores from the north tropical Atlantic.

Flowback is the portion of the injected fracturing fluid that flows back to the surface, along with oil, gas, and brine, when the well is produced. An estimated 90% of flowback in the United States is disposed of into deep EPA-licensed Class II disposal wells, with the remaining less than 10% reused, evaporated, used for irrigation, or discharged to surface streams under an NPDES permit. Of nine oil and gas-producing states studied in 2012, underground injection disposal was by far the predominant method in all but Pennsylvania where were only six active waste disposal wells. In California, Virginia, and Ohio there have been instances of illegal dumping of flowback, a precursor to possible contamination of local ground and surface water reservoirs.

The cycling of and excretion of urea by the kidneys is a vital part of mammalian metabolism. Besides its role as carrier of waste nitrogen, urea also plays a role in the countercurrent exchange system of the nephrons, that allows for re-absorption of water and critical ions from the excreted urine. Urea is reabsorbed in the inner medullary collecting ducts of the nephrons, Page 837 thus raising the osmolarity in the medullary interstitium surrounding the thin descending limb of the loop of Henle, which makes the water reabsorb. By action of the urea transporter 2, some of this reabsorbed urea eventually flows back into the thin descending limb of the tubule, through the collecting ducts, and into the excreted urine.

Cleaning is accomplished by inserting a choke plug into one of the lines leading to the transfer pump, and sucking large volumes of water from a wash-water supply tank into the choked line. This choke plug is mounted on a rod, and is inserted into the line before cleaning, and pulled out for regular milking. Due to the choke, the water, which is sufficient to completely fill the pipe, is sucked up one side of the pipeline, over the high point joining the two pipeline sections, and then flows back to the receiver bowl and transfer pump through the unchoked line. The transfer pump is then used to move the cleaning solution from the receiver bowl back to the wash-water supply tank to restart the process.

Because the equations governing the flow of current in wire antennas are identical to the telegrapher's equations, antenna segments can be modeled as two-way, single-conductor transmission lines. The antenna is broken into multiple line segments, each segment having approximately constant primary line parameters, and .Since voltage lost due to radiation is typically small compared to the voltages required due to the antenna's surge impedance, and since dry air is a very good insulator, the antenna is often modeled as lossless: The essential loss or gain of voltage due to transmission or reception is usually inserted post-hoc, after the transmission line solutions, although it can be modeled as a small value of at the expense of working with complex numbers. At the tip of the antenna, the transmission-line impedance is essentially infinite (equivalently, the admittance is almost zero) and after a brief "pile-up" at the tip, the wave reverses direction and flows back towards the feedpoint.

An example of the Saharan pump has occurred after the Last Glacial Maximum (LGM). During the Last Glacial Maximum the Sahara desert was more extensive than it is now with the extent of the tropical forests being greatly reduced. During this period, the lower temperatures reduced the strength of the Hadley Cell whereby rising tropical air of the Inter-Tropical Convergence Zone (ITCZ) brings rain to the tropics, while dry descending air, at about 20 degrees north, flows back to the equator and brings desert conditions to this region. This phase is associated with high rates of wind-blown mineral dust, found in marine cores that come from the north tropical Atlantic. Around 12,500 BC, the amount of dust in the cores in the Bølling/Allerød phase suddenly plummets and shows a period of much wetter conditions in the Sahara, indicating a Dansgaard-Oeschger (DO) event (a sudden warming followed by a slower cooling of the climate).

85 In the Canada portion of the watershed, an alpine meadow ecozone occupies most of the high ridges and valleys of the mountains.Characterization of Biomes, p. 87 In the Canadian portion of the Columbia Basin, almost half of which is part of the Kootenay River basin,The Canadian portion of the Columbia basin encompasses of which drain to the Kootenay RiverThe usage of the term "Canadian portion of the Columbia Basin" in this article denotes any parts of the Columbia River watershed that drain to the Columbia upstream of where it crosses the Canada- US border, regardless if the tributary passes through the United States as well (such as the Kootenay). Under this usage, for example, the Kootenay, which originates in Canada, flows back to the US, and returns to Canada, is considered part of the "Canadian portion", whereas the Okanogan River, which begins in Canada but joins the Columbia in the US, is not part of the "Canadian portion".

A boulder or ledge in the middle of a river or near the side can obstruct the flow of the river, and can also create a "pillow"; when water flows backwards upstream of the obstruction, or a "pour over" (over the boulder); and "hydraulics" or "holes" where the river flows back on itself—perhaps back under the drop—often with fearful results for those caught in its grasp. (Holes, or hydraulics, are so- called because their foamy, aerated water provides less buoyancy and can feel like an actual hole in the river surface.) If the flow passes next to the obstruction, an eddy may form behind the obstruction; although eddies are typically sheltered areas where boaters can stop to rest, scout, or leave the main current, they may be swirling and whirlpool-like. As with hydraulics (which pull downward rather than to the side and are essentially eddies turned at a 90° angle), the power of eddies increases with the flow rate. In large rivers with high flow rates next to an obstruction, "eddy walls" can occur.
