13. [20 Marks] (1) A piston-cylinder contains 0.1 kg of superheated water vapour at 1 MPa and 300 C (State 1) and undergoes a reversible and an adiabatic expansion (isentropic) to 100 kPa (State 2). [4] [4] (a) What is the phase of the water in State 2? If saturated, determine the quality. (b) What is the maximum work that the steam can produce in the expansion process? (Hint: Apply the first law for a closed system to solve for W) (ii) A 0.5 m rigid tank is initially evacuated. A valve connecting it to a very large supply of steam at 500 kPa and 300 C is opened and steam flows into the tank until the pressure inside the tank is 500 kPa. If the process is adiabatic, determine (a) the final temperature of the steam (C) in the tank, (b) the mass of steam in the tank (in kg), and (c) the entropy generated during the process (kJ/K).
