Two adjacent tanks are connected by a valve. The tank on the left contains 0.5 kg of water at a pressure of 11 bar and a temperature of 600 K. The tank on the right contains 0.25 kg of saturated water at a temperature of 300 K and its quality is 0.4. If the valve between the tanks is opened and the tanks are allowed to reach thermal equilibrium with the environment, what is the amount of energy transfer as heat out of the system assuming the environment temperature is 22 ?C? Use the tables in Appendix A.3 for data.

Properties in tables and charts are calculated with IF97, which implements the thermodynamic model for water documented in W. Wagner and A. Kruse, Properties of Water and Steam: The Industrial Standard IAPWS-IF97 for the Thermodynamic Properties and Supplementary Equations for Other Properties. Springer-Verlag, 1998. Reference state: u₀ = u^sat,L?? (T_triple?= 273.16 K) = 0 kJ/kg, s₀ = s^sat,L??(T_triple?= 273.16 K) = 0 kJ/ (kg ? K).
