A reversible engine working between two reservoirs at temperatures Th and Tc has an efficiency of 20%.
Question:
A reversible engine working between two reservoirs at temperatures Th and Tc has an efficiency of 20%. Working as a heat engine, it does 100 J of work in each cycle. A second engine working between the same two reservoirs also does 100 J of work in each cycle. Show that if the efficiency of the second engine is greater than 20%, the two engines working together would violate the refrigerator statement of the second law.
