Question

net positive suction head of a centrifugal pump is defined as​

Answer 1

Explanation:(NPSH stands for Net Positive Suction Head )and is a measure of the pressure experienced by a fluid on the suction side of a centrifugal pump. ... NPSH is defined as the total head of fluid at the centre line of the impeller less the fluid's vapour pressure.The difference between inlet pressure and the lowest pressure level inside the pump is called NPSH: Net Positive Suction Head. NPSH is therefore an expression of the pressure loss that takes place inside the first part of the pump housing.

Answer 2

Answer:

net positive suction head of a centrifugal pump is defined as the total head of fluid at the centre line of the impeller less the fluid's vapour pressure.
