Brine, with a specific gravity of 1.2, passes through an 85% efficient pump at a flow rate of 125 l/s. the centerlines of the pump’s 300 mm diameter inlet and 200 mm diameter outlet are at the same elevation. the inlet suction gage pressure is 150 mm of mercury (specific gravity of 13.6) below atmospheric pressure. the discharge pressure is measured 1.2 m above the centerline of the pump’s outlet and indicates 138 kpa (gage). neglecting losses in the pipes, what is the input power to the pump?
