(OP)
guys,
if we know the kilowatt of the water pump how we calculate the flow rate of the pump??????????????

Otherwise it is just a guess.

1 HP hour = 0.746 kilowatt hour
Typical combined motor and pump efficiency = 62.4%
RE: flow rate of a pump
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.

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.)

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?
