A real heat engine working between heat reservoirs at 970 K and 650 K produces 550 J
Question:
A real heat engine working between heat reservoirs at 970 K and 650 K produces 550 J of work per cycle for a heat input of 2500 J.
(a) Compare the efficiency of this real engine to that of an ideal (Carnot) engine.
(b) Calculate the total entropy change of the universe per cycle of the real engine,
(c) Also if the engine is ideal (Carnot).
