Q7: An air conditioning system is used to maintain a house at a constant temperature of 20 C. The house is gaining heat from outdoors at a rate of 21000 kJ/h, and the heat generated in the house from the people, lights, and appliances amounts to 9000 kJ/h. For a COP of 2.4, determine the required power input to this air conditioning system.

A heating system that uses heated water has a total heating load of 587 thousand btuh. How much heated water flow in gallons per minute (GPM) is required to satisfy the total load if the system is designed for 34 °F temperature change?
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…

A passive solar house that was losing heat to the outdoors at 5°C at an average rate of 50,000 kJ/h was maintained at 22°C at all times during a winter night for 10 h. The house was heated by 50 glass containers, each containing 20 L of water that was heated to 80°C during the day by absorbing solar energy. A thermostat-controlled 15-kW backup electric resistance heater turned on whenever necessary to keep the house at 22°C. Determine the minimum work input required for that night, in kJ.
