3. A triatomic gas (Cy = 3R) goes through the cycle shown below in the PV diagram. = P 14 isotherm 2P, 3 2 2 P adiabait v V Zv, (a) Find the coefficient of performance of a refrigerator running in this cycle. (b) A refrigerator is considered ”good” for K > 4.5. Would you pursue designing a refriger- ator running in the cycle above? (c) If the cycle is run in the opposite sense (CW in the PV diagram), what would be the efficiency of an engine using this cycle? Would this engine be worth building? Explain.
