Potential Energy of a Fluid at an Elevation

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