Answer / nainar ali

NPSH is the acronym of net positive suction head. which is important factor to handle the fluid in centrifugal pump.
if NPSHa(net positive suction head availabe) is greater than NPSHr(net positive suction head requirement which is determined by the pump manufacturer) then the pump can transfer the fluid from one place to other.

Answer / bibhas

Net positive suction head required is the indication of how much vacuum the seal can withstand. And NPSH available is to check the pump can handle the liquid or not. If NPSH available is less than the NPSH required that means the seal will fail to suck the liuqid( air will enter through the seal to the casing).
