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 \(\large{\frac{ft}{sec^2}}\) \(\large{\frac{m}{s^2}}\)
