# Potential Energy of a Fluid at an Elevation

on . Posted in Fluid Dynamics

A fluid at a higher elevation will have more energy than the same fluid at a lower elevation. Potential energy is normally expressed per mass unit.

## Potential Energy of a Fluid at an Elevation formula

$$\large{ E_z = z \; g }$$
Symbol English Metric
$$\large{ E_z }$$ = energy elevation $$\large{ lbf-ft }$$  $$\large{ J }$$
$$\large{ z }$$ = elevation $$\large{ft}$$  $$\large{m}$$
$$\large{ g }$$ = gravity $$\large{\frac{ft}{sec^2}}$$ $$\large{\frac{m}{s^2}}$$
