Potential Energy of a Fluid at an Elevation

Potential energy of a fluid at an elevation refers to the energy possessed by the fluid due to its position relative to a reference point, typically a reference level such as the ground or a datum.  A fluid at a higher elevation will have more energy than the same fluid at a lower elevation.

 

Potential Energy of a Fluid at an Elevation formula
\( E_z = z \;  g  \)     (Potential Energy of a Fluid at an Elevation) \( z =  E_z \;/\; g \) \( g =  E_z \;/\; z \)
Symbol	English	Metric
\( E_z \) = Energy Elevation	\( lbf-ft \)	\( J \)
\( z \) = Elevation	\(ft\)	\(m\)
\( g \) = Gravity	\(ft\;/\;sec^2\)	\(m\;/\;s^2\)
