WebMar 18, 2024 · The units of energy are feet (or meters). ‘Pressure’ is a force applied against a unit of area such as a pound of force applied to a square inch of area (psi). The liquid’s density determines the force. Rating a pump by ‘feet-of-head’ is the standard in the pump industry for a few reasons. WebThe square root then makes sense, as the root of a number >1 is smaller than the number. But the root of a number from 0-1 is larger: √0.5 = 0.707.
