Description: Pressure at the pump inlet port, including the pump acceleration pressure in the inlet, minus the vapor pressure, at the given fluid temperature; Name: Net positive entry pressure
Description: total pressure (including velocity pressure) at the pump inlet connection less the liquid vapour pressure at the present temperature of the liquid; Name: net positive inlet pressure
Description: average speed given by the stroke length multiplied with the number of complete pumping cycles of the piston, plunger or piston attached to the diaphragm per minute (stroke per minute or pump crank speed); Name: piston velocity
