The Labadie power plant at Saint Louis has two centrifugal pumps per condenser to pump feed water into the boiler. Each pump is designed to deliver 5500 gallons per minute with a discharge head of 7050 ft of water. Determine the power requirement of the driven motor, in hp and in kW, if the pump efficiency is 85 percent. Also, determine the power required if the pump speed is increased to increase the flow rate and the head differential to 7150 ft of water.
