Water Distribution: Assume that the pipe has a 12” diameter, is plastic with C = 140 and has a total elevation change of 20 ft. How much energy is required per year to pump the water through the pipe to the customer? Assume that your pump is 80% efficient. How much will it cost to pump the water for 3 months in summer? (0.759 kW = 1 hp, 1 kWh costs $0.10)
