Suppose you have a cylindrical tank of water that is filled to height h. Total mass of water is M. How do you calculate the potential energy of water relative to the base of the tank?

fuzzylogic said:I just want to know what the stored p.e. is
Yes, that's fine.fuzzylogic said:does this make sense:
g=gravitational acc
y=water level from base
A=area of water surface
r=water density
m=total mass of water
U=PE
then dU=grAydy
U=1/2grAh^2=1/2mgh (m=rAh)
To calculate the potential energy of water in a tank, you will need to know the height of the water in the tank, the acceleration due to gravity, and the mass of the water. The formula for potential energy is PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height.
The unit of measurement for potential energy is joules (J). This is a standard unit for measuring energy.
Yes, potential energy can be negative. This occurs when the height of the water is below the reference point, such as ground level. In this case, the potential energy would be considered as negative.
The potential energy of water in a tank does not directly affect the pressure. However, as the height of the water increases, so does the pressure at the bottom of the tank due to the weight of the water above it.
No, the potential energy of water in a tank is not constant. It changes as the height of the water in the tank changes. As the water is used or added to the tank, the potential energy will also change accordingly.
