5. Air initially occupying a volume of 1 m at 1 bar, 20 C undergoes two internally reversible processes in series Process 1-2: compression to 5 bar, 110C during which pV" = constant Process 2-3: adiabatic expansion to 1 bar (a) Sketch the two processes on p-v and T-s coordinates. (b) Determine n. (c) Determine the temperature at state 3, in C. (d) Determine the net work, in kJ. Ans: n = = 1.19, T3 242 K, Wnet: = -37.8 kJ.
