A Carnot engine is coupled to a Carnot refrigerator so that all of the work produced by the engine is used by the refrigerator to extrac heat from a heat reservoir at 0C at the rate of 29kJs1. The source of energy for the Carnot engine is a heat reservoir at 250C. If both devices discard heat to the surroundings at 25C, how much heat does the engine absorb from its heat-source reservoir? The engine absorbs kJs1 of heat from its heat-source reservoir. If the actual coefficient of performance of the refrigerator is =0.6Carnot and if the thermal efficiency of the engine is = 0.6Carnot,, how much heat does the engine absorb from its heat-source reservoir? If the actual coefficient of performance of the refrigerator is =0.6Carnot and if the thermal efficiency of the engine is = 0.6Carnot,, the engine absorbs kJs1 of heat from its heat-source reservoir
