A fireboat pump draws seawater (density=1.95 slugs/ft^3) from a 6 inch diamter submergred pipe that reaches 6 feet under the free surface and discharges 120 ft/s through a 2 inch diamter nozzle 10 feet above the free surface. If the pump is rated at 12 horsepower, how effiecient is the pump? Assume uniform steady flow and a total head loss of 3 ft through the pumping system.
