Suction Specific Speed (S) like Impeller Specific Speed (Ns) is a parameter, or index of hydraulic design describing the suction capabilities and characteristics of a given first stage impeller.Input values for Flow and NPSHR that correspond to the the pump performance at optimum (or best) efficiency point. In this example, calculate the suction specific speed in either Metric or US units.
