Question:
Water at 60°F is pumped from a reservoir to the top of a mountain through a 6-in. Schedule 120 pipe at an average velocity of 12 ft/s. The pipe discharges into the atmosphere at a level 3,000 ft above the level in the reservoir. The pipeline itself is 4,500 ft long. If the overall efficiency of the pump and the motor driving it is 70 percent and the cost of electric energy to the motor is 4 cents per kilowatt hour, what is the hourly energy cost for pumping this water?
