Mr. Lamar sorry for the question, but what is cavitation?

Good question. Marks ME handbook defines  it as "the formation and collapse
of gas or vapor filled bubbles."

In this context I like to think of it as that state where the pump
stops pumping fluid.

Paul,

I think this is an over simplification.  Pumps can cavitate and
continue to pump.  Certainly extremely severe cavitation would
produce reduced or even no flow, but I am aware of pumps that
have been severely damaged by cavitation while providing
useful service in chemical process systems.

OK lets say it is the point where the flow stops increasing as a
direct function of RPM. Bill, where can I find some chart maps of
flow verses RPM and differential pressure for centrifugal pumps?
