3. A piston-cylinder device contains 1.2 kg of saturated water at 200C and x=0.8. Heat is now transferred to steam, and steam expands reversibly and isothermally to a final pressure of 800 kPa. Determine; a) initial pressure, volume(m3) and entropy(kJ/K) b) final volume(m3) and entropy (kJ/K) c) entropy change of the steam during the process and corresponding the heat transferred (kJ) d) and the work done during this process (kJ). e) Draw a T-s diagram for water and show state points and process line.
