Water contained in a piston - cylinder assembly, with initially quality of 0.25

Question

Water contained in a piston - cylinder assembly, with initially quality of 0.25 ( 25% ) , is heated until the piston hits the stops. Heating continues until the pressure is 3 bar. The mass of the piston is 40 kg, and its diameter is 10 cm. The atmospheric pressure is 100 kPa. The initial and final positions of the piston are as shown m the Figure below Find The initial pressure. The mass of water. The quality when the piston hits the stops. The final temperature. The work and heat transfer for each process The force exerted on the stops at the final state. Sketch p - v and T - v diagrams showing states and the processes. Figure: Piston - cylinder assembly for problem 3.
