If I know the available head of tank or the depth of tank from which some chemical is to be pumped at some particular distance (lets suppose 1km) and the pipe diameter is 10 inches, then how do I select the adequate horsepower motor for optimum performance? The pump is centrifugal and the flow rate is known.
Have an insight or suggestion?

Re: How To Calculate Pump Horsepower
4 November 2008 at 1:29pmThe following formula can be used to calculate pump horsepower (HP):
HP = (gallons per minute x head in feet x specific gravity of fluid) / (3960 x efficiency of pump)
