Description: relationship between the total head of the pump and the rate of flow at given operating/rated conditions of speed and liquid; Name: pump head capacity curve
Description: pump H(Q) curve where the maximum head and shut-off head are coincidental, and the total head declines continuously as the rate of flow increases; Name: Pump H(Q) curve
Description: amount of the absolute value of the total head above the head, equivalent to the vapour pressure of the liquid at the particular temperature, with reference to the NPSH datum plane; Name: net positive suction head
