A gas undergoes a cycle in a piston–cylinder assembly consisting of the following three processes:Process 1–2: Constant pressure, p = 1.4 bar, V1 = 0.028 m3, W12 = 10 kJProcess 2–3: Compression with pV = constant, U3 = U2Process 3–1: Constant volume, U1 - U3 = -20 kJThere are no significant changes in kinetic or potential energy.(a) Calculate the net work for the cycle, in kJ.(b) Calculate the heat transfer for process 1–2, in kJ.

awuIs 2 kg of air undergoes a power cycle undergocs a power cycle consisting of the following processes: Process 1-2: Constant-temperature expansion from p, = 4 bar, v, = 1 m³ /kg, to p2 = 2 bar, v2 = 2 m3/kg. Process 2-3: Constant-pressure compression to T3 = 696.9 K. Process 3-1: Constant-volume heating to state 1. Assume ideal gas behavior and neglect kinetic and potential energy effects. Show that T; = 1393.7 K and find T Sketch the cycle on a T-v diagram and label the states. Find the work done and heat transferred during cach process to complete this chart: b C. Process W (kJ) Q (kJ) iti 1-2 2-3 3-1 TOTAL Find the thermal efficiency of the cycle. For an energy balance on the entire cycle (1-2-3-1), what should the change in system energy be? Does that hold in this case?
