Description: relationship between the npshr and the rate of flow at given operating/rated conditions of speed and liquid; Name: pump npsh curve
Description: Relationship between the net positive suction head required and the rate of flow at given operating conditions of speed and liquid ; Name: Pump NPSH curve
Description: pump h(q) curve where the maximum head (peak point) and shut-off head are not coincidental, or the total head does not decline continuously as the rate of flow increases; Name: stable pump H(Q) curve
