Hence find the total work over one cycle. b) Find the heat exchanged along each path. Hence find the heat entering the cycle, QH and the heat leaving the cycle, Qc. c) Calculate the efficiency of this Carnot cycle. Hence find the temperature of the path from c→ d. d) Calculate the entropy change AS along each path. e) Hence sketch the T-S diagram corresponding to the Carnot cycle.
