A irreversible heat engine operating between heat reservoirs at 600 K and 300 K has half the efficiency of a Carnot engine. Calculate the entropy change of the working fluid in the engine which is the system, the surroundings, and the universe per cycle of the engine if 1000 J are extracted from the hot reservoir per cycle.
I know the efficiency of the engine would be 1/2(1-300/600) which is equal to 1/4 but how do I relate this with the entropy change, I'm really confused. Please help out..
Thanks
