Trying to calculate the power of a pump, it's pumping water.(adsbygoogle = window.adsbygoogle || []).push({});

It has a flowrate in and out in kg/s. Surely I should look up the enthalpy values and just mutiply with the flow rate to get power in kW.

However I know that if I convert flowrate to m3/s by dividing 1000 and multiplying by the pressure difference would I not be doing an energy balance? I get a different answer in both methods, which one is the valid method here?
