Do you have data sheet on the motor and flow curve for the pump?
Otherwise it is just a guess.

As bimr says.
First you need to know the DIFFERENTIAL pressure or head of the pump, not just its output pressure.
Then it's a bit of a guess as the efficiency. The small units ( 1-2 kW or less), sometimes have combined efficiencies of 40% or less.
The nameplate on the pump normally tells you all or just google the type of pump.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

If you know the pressure across the pump and the power being used, using the calc.given by bimr-you could make a very wild guess as to the flowrate, bear in mind that it might be a meaningless crazy answer.
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.)

"5 gallon buckets are also effective."
But we're all assuming it's a small pump. It could be a 500kW pump - who knows?
It could be a PD piston pump - who knows?
rish916 - do you know??

Sometimes it beats me why we even answer such questions, you would think we had nothing to do
