"WebThe second characteristic for pump sizing is the pump head or discharge pressure. The term “head” derives from the height of water that the pump can overcome at a given flow, generally expressed as feet of water (1 foot water = 0.43 psi = 6.3 bar). Operators often think of head as the discharge pressure at the pump, but many different ... " - Reading pump curves for dummies
