A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: Process 1-2: Expansion with PV" =Constant (n=2.5), from P. = 1.5 bar, V, - 1.5 m to V2 = 2.5 m², U2-U1 = 150 kJ. Process 2-3: V2=V3 and P3 = P Process 3-1: P3 = P, and Q3-1 = 0 (a) Identify the type of process from 1-2, 2-3 and 3-1. (b) Formulate the necessary equations involved in all the processes. (c) Calculate the work(W), heat (Q) and change in internal energy (AU) of each process. (d) Draw the PV diagram of the cyclic process. (e) Determine the net-work of the cycle in kJ and explain is this a power or refrigeration cycle?
