In the water analogy of an electric circuit what corresponds to the power supply the resistor and potential difference?
Power supply: Water pump, producing pressure at its output valve.Resistor: A section of pipe. Flow of water loses energy on the way through, due to friction with the pipe's interior wall.Potential difference: Difference in water pressure between the beginning and end of the pipe section.
Pressure in a pipe draining an elevated water tank depends on the height of the tank but does it also depend on how full the tank is?
Yes, the pressure in the pipe is dependant of the height of the column of water above the point you are considering.
Why is a fountain of water seen rising out of a leaky pipe?
The water in your pipes is under pressure so that it comes out of the tap when you turn it on. If there is a hole in the pipe (i.e. a leak) then the water will come out under pressure, the same as if you turned on your tap - if this hole faces upwards then there will be a jet or water like a fountain. The height of this jet is dependant upon the pressure of the water
What is thePressure of gravity fed water tanks?
Measure the vertical distance from the top of the water in the tank to the point of use. Multiply that distance by 0.44 to get the answer in psi. Example: if the top of the tank is 20 feet above the point of use, the water pressure at the point of use will be 8.8 psi. Note, this does not account for friction losses in the pipe. If the pipe runs a long distance from the tank to the point of use, there will be pressure losses in the pipe, especially if the pipe is a small diameter. The larger diameter, the less those pressure losses will be.
Why the pressure of fluid decreases as area of pipe decreases?
Your question has an error, the pressure increases as area of pipe decreases or the pressure decreases as the area of pipe increases. Answer: Conservation of energy

How do you increase water pressure in a model water tower?
Water pressure in real towers is created by the height of the tower above the surface of the earth, and the diameter of the pipe supplying the water to the output. The same should hold true for a model water tower.
When dealing with water pressure there is no head unless the pipe is blocked off right?
If water is flowing through pipe, no head pressure can build up. Blocking off flow of water will create head pressure in pipe as long as pipe is vertical. A vertical column of water creates head pressure.
Do you have a solution to stop the drop in water pressure when using shower and flushing toilet?
Increase your main line pipe size. When you have a small pipe installed, and while you showering the toilet is flushed it has to distribute the amount of water running in the pipes, resulting in the drop in pressure. Once you have increased the pipe size, you'll notice that the extra volume of water will accommodate for the extra water needed to fill the cystern while showering, therefore fixing the problem with a drop in pressure.
Why isn't cold water running from a previously frozen pipe when hot water is running from that faucet?
Rust popped off inside the pipe and plugged the faucet.
Why is my Water pump not pressurizing the water system on the house?
Pump broken, even if it seems to be running, OR, pump needs "priming" (get water into the pump since it will not suck air), OR something is blocking the water from exiting the pipe (ie, back pressure, as if "destination is already full") OR there is no water feeding the pump. OR, maybe the other side of the pipe is leaking, hence no "pressure"
Installation of the drain pipe for the temperature and pressure relief valve?
It is the drain for the Temperature and Pressure relief valve (T&P valve, or TPV). It's function is to release pressure from the water heater if the pressure or temperature of the water exceeds preset limits. Do not cap off the pipe, or remove the T&P valve or alter it in any way. Doing so could cause serious injury or death! If you notice water dripping or running from the pipe, call a plumber to check it.
Will water flow out of a pipe if the pipe is covered with water?
Yes, as long as the water coming out of the pipe has a greater pressure than the water that is covering the pipe. If it is the other way around, the water covering the pipe will actually flow into the pipe. Think about it. It just makes sense.
When water moves from large pipe to small size pipe then what will be the pressure?
The pressure will rise, but you haven't given us anyvolume or pressure figures to begin with .
What condition is necessary for the sustained flow of water in a pipe?
negative pressure is needed for a sustained flow of water in a pipe.

Why would you lose water pressure when you have no water running anywhere else?
You must have a leak somewhere. If you are on a well check the pressure tank, make sure there is adequate air pressure. ( check at nipple on top, should be in excess of 25 psi) Check the pipe to well. Listen carefully at the well while pump is running. If there is a leak in the down pipe or lower check valve you will hear water hissing. If none of these ideas work, post again and be more specific about your system.
