1.) A Carnot engine is coupled to a Carnot refrigerator so that all the work produced by the engine is used by the refrigerator in extraction of heat from a heat reservoir at 270K at the rate of 4 kJ/s. The source of energy for the Carnot engine is a heat reservoir at 500K. If both devise discard heat to the surrounding at 300K, a. How much heat does the engine absorb from the 500K reservoir? b. If the actual efficiency of the engine is n= Ncarnot /1.5 and the COP = COPCarnot/1.5, how much heat does the engine absorb from the 5O0K reservoir?
