A heat engine operates between two reservoirs at 8000 C and 200 C. One-half of the work output of the engine is used to drive a Carnot heat pump that removes heat from the cold surroundings at 20 C and transfers heat to a house maintained at 220 C. If the house is losing heat at a rate of 62,000 kJ/h, determine the minimum rate of heat supply to the heat engine required to keep the house at 220 C.

Consider the diagram shown below for the given system.

Question

A heat engine operates between two reservoirs at 800⁰ C and 20⁰ C. One-half of the work output of the engine is used to drive a Carnot heat pump that removes heat from the cold surroundings at 2⁰ C and transfers heat to a house maintained at 22⁰ C. If the house is losing heat at a rate of 62,000 kJ/h, determine the minimum rate of heat supply to the heat engine required to keep the house at 22⁰ C.
