Potential Energy of a Fluid at an Elevation

on . Posted in Fluid Dynamics

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 \(ft\;/\;sec^2\) \(m\;/\;s^2\)
