The biggest problem with this is that you don't necessarily know the pressure at the pump's inlet, and you need the inlet/oulet pressure differential to be able to use the pump's PQ curve.
Then there is the issue of how well the pump actually matches the spec'd PQ curve, the difference between the voltage at your wall outlet vs the supply used to generate the pump curve, etc.
