The cycle in question for reference: [4pts] for parts (b) and (c) together P (b) Compute the ratio TMAX/TMIN of 1-2 and 3-4: adiabatic the highest and the lowest temperature 2-3: constant pressure 4-1: constant volume the gas achieves as it goes around the cycle. Let P3 = P2, (c) Compute work done by the gas P1 = 4P2 during segment 1-2. 3 2 and PA = 3P2. Assume that there are N molecules of gas, each with f quadratic degrees of freedom. During adiabatic compression, PV and VT/2 are constant, y = (f + 2)/f. You may use P2 and V2 in your answer, but not the other pressures or volumes. Question 5. Solution: (b) TMAX T1 PIV1 4P2 V4 pl/y P2 1/7 4 4 4 = 4. 3-1/7 = TMIN T3 P3 V3 P2 V3 pl/y 3P2 3f/ (f+2)
