Pump is moving 475gpm of water at 75ºF from an open reservoir 4feet below the elevation of the pump. The inlet to the pump is located 2 feet below the surface of the water and 8feet from the pump entrance, horizontally. The inlet pipe is 4-inchgalvanizediron pipe that has an abrupt entrance (C = 0.5) and one90º elbows(C = 0.9). How muchnet positive suction pressure is available at the pump in
