Pump head equations
WebOct 8, 2024 · 10/08/2024. The term “total head” (H) is used to describe the energy in pumping systems and is how manufacturers represent the performance of their pumps as … WebWhen pumping into pressure, you’ll have to account for increased head on the pump. The formula is based on gravity. 1 psi = 2.31 feet of head. So a 40 psi pressure tank is 92.4 feet of head and significant with some pumps so good to remember to take into account when sizing your pump!
