What are NPSH and suction power of a pump?

It is the acronym of Net Positive Section Head and it is the total suction head - in m - determined at the suction nozzle and correct to datum, less the vapour pressure of the liquid - always in m -. In other words it is an analysis of energy conditions of suction side of a pump to determine if the liquid will vaporize at the lowest pressure point in the pump. To ensure that a pump works correctly along the whole performances curve, it is necessary, for each point of the curve that: NPSH available > NPSH requested.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
