A pump station must fill a 15-million-gallon tank within 10 hours. The pump must overcome a total head of 115 feet (this include both elevation head and friction). Assume the pump and motor efficiency are 0.75 and 0.90, respectively. Water temperature is 80°F. Assume the cost of electricity is $0.22/(kW-h). What is the yearly cost to operate the pump station? Round your answer to the nearest whole dollar. (Conversion factor: 1 horsepower = 745.7 W)
