6. Consider a heat engine (the Stirling Engine), following steps A B and C D being isothermal and steps B-C and D->A being isochoric (constant volume). The temperature at C D (TH) is 2500 K and the temperature at A B (TC) 500 K. The volumes of gas at A and D are 0.5 mº, and the volumes of gas at B and C are 0.49 m². Note: the working fluid in this engine is an ideal monatomic gas (10 moles). a) (2 pts) Please draw P-V diagram. b) (4 pts) What is the pressure at each point (A, B, C, D)? c) (4 pts) How much work is performed by the gas in each step? d) (4 pts) What is the network after a complete cycle? e) (2 pts) How much heat is absorbed by the gas? f) (2 pts) How much heat is discarded by the gas? g) (2 pts) What is the Carnot efficiency for this engine? h) (1 pts) What is the change in entropy (ASB-D) during B-D? i) (1 pts) What is the change in entropy (ASD-B) during D->B? j) (1 pts) What is the net change in entropy (ASuniverse) between the steps in question h and question i?
