A centrifugal pump discharges 2,200 GPM through a 12-inch diameter impeller. The fluid leaves the impeller with a tangential velocity of 20 ft/sec. If water, @ 68°F, enters the impeller via radial flow (L.E. no whirl), and the inner radius and thickness of the impeller are 2-inches. (Assume a constant thickness of the impeller) and if the pump speed is 1,660 rpm, with a head loss of 2-feet. What is the horsepower input to the flow by the pump?
