If a reservoir was at the top of a cliff and a house was immediately below it with another house at the bottom of the cliff would the latter throw the water further from a hose due to the steep descent?
sophiecentaur said:Apart from energy losses in the pipes, the situation should be the same in all cases. The kinetic energy of the water leaving the hose (hence, the speed) would be equal to the Gravitational Potential Energy at the surface of the reservoir.
Nugatory said:You sure? The relative height of a water tower and the faucet from which we draw water does make a difference in the speed with which the water flows. Higher pressure at the lower location means more force acting on a a unit volume of water at the nozzle, hence more acceleration, greater speed, more kinetic energy. The greater speed translates into greater flow so the water level in the reservoir drops more quickly, transferring more potential energy per unit time.
I may be reading OP's (less than perfectly clear) question differently than you. If so... never mind.
The location of the reservoir can have a significant impact on the water throw from the hose. If the reservoir is located at a higher elevation, the water will have more potential energy and the throw will be greater. However, if the reservoir is located at a lower elevation, the water throw will be less as there is less potential energy.
Yes, the distance between the reservoir and the hose can affect the water throw. The longer the distance, the more friction the water will encounter as it travels through the hose. This can result in a decrease in water throw.
Yes, there can be a difference in water throw depending on where the hose is connected to the reservoir. If the hose is connected to a lower point on the reservoir, the water will have less potential energy and the throw may be shorter. On the other hand, if the hose is connected to a higher point on the reservoir, the water may have more potential energy and the throw may be longer.
Yes, the shape of the reservoir can have an impact on the water throw. If the reservoir is more narrow, the water may have a higher velocity as it exits the hose, resulting in a longer throw. If the reservoir is wider, the water may have a lower velocity and the throw may be shorter.
The pressure of the water in the reservoir can greatly impact the water throw from the hose. The higher the pressure, the more force the water will have and the longer the throw will be. However, if the pressure is too high, it can cause the hose to burst or the nozzle to become dislodged, resulting in a shorter throw. It is important to maintain a safe and appropriate water pressure for optimal water throw.
