Air in a piston cylinder assembly undergoes a thermodynamic cycle consisting of three internally reversible processes in series:
Process 1-2: Constant volume heating from T1=288K, p1=0.1 MPa to p2=0.42 MPa
Process 2-3: Constant pressure cooling
Process 3-1: Isothermal heating to the initial state
Employing the ideal gas model with cp= 1 kJ/kgK, evaluate the change in specific entropy, in kJ/kgK for each process. Sketch the cycle on p-v and T-s coordinates. For each process, associate work and heat transfer with the areas on these diagrams.
