A Carnot engine is coupled to a Carnot refrigerator so that all of the work produced by the engine is used by the refrigerator in extraction of beat from a heat reservoir at 0°C at the rate of 35 kJ s-l. The source of energy for the Carnot engine is a heat reservoir at 250° C. If both devices discard heal to the surroundings at 25°C. how much heal does the engine absorb from its beat-source reservoir?
If the actual coefficient of performance of the refrigerator is ω = 0.6 ωcannot and if the thermal efficiency of the engine is η = 0-6 ηcaraot how much heat does the engine absorb from its heat-source reservoir?
