real pump curve

real pump curve

(OP)
Hello All

Let's suppose I've got in hands the pump theoretical curve (given by the Euler equation) and the efficiency pump curve. Can I estimate the real pump curve simply by multiplying the theoretical curve by the efficiency at any flow point?

Thank you in advance

RE: real pump curve

Sure, and it will have an uncertainty of the two sources combined.
It is fine if you considering a design for a pump, but not for application.

RE: real pump curve

The only way to establish a known performance is a full hydraulic performance test, the reason major pump manufacturers have expensive and elaborate test facilities.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

RE: real pump curve

I am amazed that you can not get the pump curve from the manufacturer.
