# Potential Energy of a Fluid at an Elevation

Written by Jerry Ratzlaff on . Posted in Electromagnetics

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.

## formula

$$E_z =z g \;$$

Where:

$$E_z$$ = energy elevation

$$z$$ = elevation

$$g$$ = gravity
