Description: h(q) curve for pump where the peak point and shut-off head are not coincidental, or the total head does not continuously decline as the flow rate increases; Name: pump H(Q) curve stable
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
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
