Head to pressure calculation
Identical pumps will develop the same head when running at the same speed but the discharge pressure is quite different due to the different densities of the liquids. It can be simpler to discuss the performance pumps in terms of head rather than pressure since the use of head makes the pump curve applicable to any … See more Since pressure gauges often are calibrated in pressure - psi or bar - a conversion to the heads commonly used in pump curves - like … See more The head in feet water column can be calculated from pressure 100 psi with eq. 3 as: Where specific gravity of water = 1.
