(b) A piston-cylinder assembly containing 2 kg of water initially at 0.35 MPa and 350 °C undergoes an isobaric process until it becomes saturated vapor. It is then followed by another constant volume cooling process until the pressure becomes 0.2 MPa. Neglecting the changes in kinetic energy and potential energy: (i) Compute the final temperature. (ii) Compute the total work transfer of the system. (iii) Show the processes on a T-v diagrams with respect to the saturation lines (4 marks) (5 marks) (2 marks)
