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.

yes u all are right....:P


but better stick to the dick, u fools

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).

Greetings This question is about hydraulics and I request an expert to answer it. A simple hydraulic machine is made up of two heads, a larger one with a larger force inside a wider pipe and a smaller one with a smaller force inside a smaller pipe in width as in the second picture on this link: http://science.howstuffworks.com/hydraulic1.htm The question is this: what happens if the smaller head and the smaller force doesn’t exist but the smaller pipe is high enough to take all the liquid? For example the larger head is 1.00 sqr metre and can go down 1.00m under a weight of 100.00kg. The cross sectional area of the smaller pipe is 0.001 sqr metre. Now when the larger head goes down 1.00m, how high the liquid from the wider pipe can go into the smaller pipe of the cross sectional area of 0.001 sqr metre? Regards
