Calculate pump head equation
WebThe head of the pump depends on the flow rate and it is zero at the maximum head and diminishes as the flow increases. To verify the discharge head of a pump, a pressure gauge is used. Pressure gauges measure in units called psi or pounds per square inch. The formula gives the conversion of pressure to head. more info WebIf the fifth floor is 55-feet high, then divide 55-feet by 2.31-feet/psi to determine the head loss of pushing the water up five floors. This yields 23.81-psi, which then must be added to the minimum usable water pressure for the occupants of 45-psi, for a minimum required pressure of 68.80-psi. Adding 20-per-cent safety margin would determine ...
