Problem 8The demand for electric power is usually much higher during the day than it is at night, andutility companies often sell power at night at much lower prices to encourage consumers to usethe available power generation capacity and to avoid building new expensive power plants thatwill be used only a short time during peak periods. Utilities are also willing to purchase powerproduced during the day from private parties at a high price. Suppose a utility company is selling electric power for $0.07/kWh at night and is willing to pay $0.15/kWh for power produced during the day. To take advantage of this opportunity, an entrepreneur is considering building a large reservoir 100 m above the lake level, pumping water from the lake to the reservoir at night using cheap power, and letting the water flow from the reservoir back to the lake during the day, producing power as the pump–motor operates as a turbine–generator during reverse flow. Preliminary analysis shows that a water flow…
