Calculate the electrical power input to an electric motor (nm = 95%) to drive the pump (np = 85%). The pump is used to add energy to  flowing oil of 1,500 GPM through 1,500 feet of 81 2'' diameter cast iron pipe. The density and viscosity of the oil are 1.75 slug/ft3 and 1.15 x 10-4 ft2/s, respectively.
