A gas within a piston-cylinder assembly undergoes a three processes: Process 1-2: Constant volume, V = 0.06 m², U2 - Uı = 40.4 kJ Process 2-3: Expansion with PV= constant, U3 - U2 = 0 Process 3-1: Constant pressure, P =3 bar, W31 = (-20) kJ There are no significant changes in kinetic or potential energy. (a) Identify the process on a sketch of p-V diagram plotted for the cycle. (b) Formulate the expression for heat transfer for process 2-3 and process 3-1. (Hint: Apply first law of thermodynamics for closed systems) Solve to find the net-work for the cycle and heat transfer for the process 2-3 and Heat transfer for process 3-1, in kJ Identify if the above system executes a power cycle or a refrigeration cycle. Give (c) (d) reason.
