A rigid tank has two compartments, one 500 times larger than the other. The smaller part contains 2 kg of compressed liquid water at 1 MPa and 25oC, while the other part is completely evacuated. The partition is now removed, and the water expands to fill the entire tank. Heat transfer with the atmosphere at 25oC is allowed, and, as a result, the final temperature after mixing is 25oC. Determine the final
(a) Pressure.
(b) Quality of the mixture. Also find
(c) The entropy change of water.
(d) The entropy generation during the process.
