Calculating the yearly energy cost for the motor of a pump in the wastewater treatment plant.

1. If you had been tasked to remove the water from New Orleans after Hurricane Katrina would you select a radial flow, mixed flow or axial flow pump for this purpose? describe your choice.

2. A pump for a wastewater treatment plant has a motor with a nameplate rating of 20 HP. When the pump operates measured power draw is equivalent to 15 HP. The pump operates 80 percent of the time. The energy company bills the plant at a rate of $0.15 per kilowatt-hour of energy used. Describe how to find out the yearly energy cost for the motor. Assume the motor is 100 percent efficient. (Note also that 1 kilowatt-hour = 3,600 kJ although you don't necessarily need this conversion.)
