Q1: A closed system contains air at a pressure 1bar, temperature 300K and volume 0.018m3. This system undergoes a thermodynamic cycle consisting of the following three processes in series: (i) Constant volume heat addition till pressure becomes 5 bar, (ii) Constant pressure cooling, and (iii) Isothermal heating to initial state. (1)Represent the cycle on T-S and p-V plots (2) Evaluate the change in entropy, work, heat and change in internal energy for each process. Take cv=0.718kJ/kgK and R=0.287kJ/kgK
