A system consisting of 2 kg of ammonia undergoes a cycle composed of the following processes: 

Process 1–2: constant volume from p1 =10 bar, x1 = 0.6 to saturated vapor

Process 2–3: constant temperature to p3 = p1, Q₂₃ = 228 kJ

Process 3–1: constant pressure Sketch the cycle on p–v and T–v diagrams.

Neglecting kinetic and potential energy effects, determine the network for the cycle and the heat transfer for each process, all in kJ.
