During the cycle, the heat is added into the air in process 2-3, and process 3-4. heat is rejected in process 5-1 only. there is no heat transfer during process 1-2 and process 4-5. so q_in=q_23+q_34, and q_out=q_51. let analyze this thermodynamic cycle. process 3-4: constant pressure with heat addition into the system. (a) define your system and draw a boundary to separate your system and the surroundings. (b) for process 3-4 only, write down the energy conservation equation for the system. (c) if q34 (heat transfer into the system during process 3-4), p3 (pressure at state 3), v3 (volume at state 3) and v4 (volume at state 4) are given, rewrite energy conservation equation for part (b) and find total internal energy change for this process δu34.
