A real (non-Carnot) heat engine, operating between heat reservoirs at temperatures of 510 K and 270 K performs 2.4 kJ of net work and rejects 37.6 kJ of heat in a single cycle. (a) What is the thermal efficiency of this heat engine? (b) How much entropy is created by one cycle of the engine? Assume the entropy of the engine itself is the same at the start and end of the cycle. (c) How efficient would an ideal (Carnot) heat engine be for the given temperatures?
