Initially 10 kg of saturated liquid water at 400 K and 2 kg of saturated water vapor
Question:
Initially 10 kg of saturated liquid water at 400 K and 2 kg of saturated water vapor at 300 K are together in a sealed, constant volume adiabatic container. After a time the water adjusts to a uniform state within the tank. What are the pressure and temperature in this final state, and what are the final volumes of the liquid and vapor? The graphs in Appendix A.3 may be used along with the tables in solving this problem.
