Question

What does NPSH stand for?

(a) Net positive suction head

(b) Net positive super head

(c) Net planar suction head

(d) Non-planar suction head

I have been asked this question in an online quiz.

The query is from Model Testing of Partially Submerged Bodies in chapter Dimensional and Model Analysis of Fluid Mechanics

Answer 1

Correct choice is (a) Net positive suction head

The explanation is: NPSH stands for Net Positive Suction Head. The main function of the NPSH test is to measure the ability of the pump. It helps to avoid cavitation at the inlet section of the pump.
