Flowing liquid has three types of energy;
Pressure Energy If there is a pressure p on the surface area A of liquid and liquid covers a distance l, due to this , then
pressure energy = pAl
pressure energy per unit volume = p
Kinetic energy If mass m and volume V of a liquid is flowing with velocity v, then
kinetic energy per unit volume = dV2/2
where, d = density of liquid
Potential energy If mass m of liquid is at a height h above the earth's surface, then potential energy is
= mgh
