What are the energies possessed by a liquid ? Write down their equations.

Explanation

A liquid in motion possesses following three types of energy .
(i) Kinetic energy : It is the energy possessed by a liquid by virtue of its motion.
K.E. = `1/2 m v^2`
K.E. per unit mass = `(1/2 mv^2)/(m) = (v^2)/2`
(ii) Potential energy : It is the energy possessed by a liquid by virtue of its height above the ground level.
P.E. = mgh
P.E. per unit mass `= (mgh)/(m) = gh`
(iii) Pressure energy = It is the energy possessed by a liquid by virtue of its pressure.
Pressure energy per unit mass `= P/(m//v)`
