# Potential Energy of a Fluid at an Elevation

Written by Jerry Ratzlaff 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

 $$\large{ E_z = z \; g }$$

### Where:

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