For well and pump systems, the point in the well pump on-off cycle during which you make the measurement - water pressure varies between the pump cut-in (typically 20 or 30 psi) and cut-out pressure (typically 40 or 50 psi as the pump turns on and off while water is running, so the flow rate is not constant. The flow rate of water in gallons per minute, or gpm, can be calculated with the help of the Bernoulli equation and careful unit conversion. If the pressure is known in pounds per square inch, or psi, at two locations along the pipe, then the Bernoulli equation can be used to determine the velocity of the water. or how quickly work can be done.
