Suction Specific Speed Formula at Mildred Reynoso blog

Suction Specific Speed Formula. Nss is a dimensionless parameter that describes the relationship between the speed, the flow rate and the net positive suction head required (npshr) of the rotating impeller. When computing suction specific speeds, the value of q is flow rate, in gallons per minute, per suction inlet, or impeller eye. Suction specific speed is an index number for a centrifugal pump similar to discharge specific speed and is used to define its suction characteristic. The suction specific speed (nss) is calculated by the same formula as pump specific speed (n s) but uses npshr values in feet in. The equation for suction specific speed is the same as specific speed, except that npshr is substituted for head, as follows: Suction specific speed is a special case of the same equation used for assessing the safe range of flow rates around a pump’s bep or, when working to a specific minimum suction. Suction specific speed (nss) can be thought of as one index or tool in a mix of several tools regarding impeller design.
