A room with walls that pass heat at a rate B(Toutside - Tinside) is cooled by an air conditioner that has half the efficiency of an ideal Carnot machine. It is powered by a 1-kW electric motor that is 90 percent efficient in converting electric power into mechanical work. For B = 700 J s-1 K-1 and an outside air temperature of 37 °C, what is the minimum temperature that can be reached inside the room?

A heat pump is used in place of a furnace for heating a house. In winter, when outside air temperature is 15F, the heat loss from the house is 100,000 btu/h. The inside is maintained at 70F. Find the Carnot COP, the minimum electric power required to operate the heat pump in kW, and the actual electric power to operate the heat pump with a COP of 3.

Select all that are true. Group of answer choices A heat engine will theoretically be more efficient when it is colder out- when there is a bigger difference in temperature between the hot and cold reservoirs. A heat pump has a higher maximum ideal coefficient of performance when the temperature outside is closer to the temperature inside your house. It is likely that one day there will be no temperature difference between any two points in the universe and it...

Uniform area, heat transfer problem A stove's walls are made up of a flat inner insulating board 0.01m thick (thermal conductivity: 0.2 W m-1K-1) and a flat outer steel sheet 0.01m thick (thermal conductivity: 26 W m-1K-1). A mineral-wool (thermal conductivity: 0.065 W m-1K-1) is placed between these sheets. The inside temperature of the wall is 773K, how thick does the insulation have to be to maintain the outside wall temperature at 323K ? Assume that the ambient air temperature...
