HW3- A Carnot heat engine operates between two reservoirs at 800 and 20°C. One-half of the work output of the heat engine is used to drive a Carnot heat pump

that removes heat from the cold surroundings at 2°C and transfers it to a house maintain edat 22°C. If the house is losing heat at a rate of 93,000 kJ/h, determine the minimum rate of heat supply to the heat engine (in kJ/h) required to keep the house at 22°C.
