Saturated water vapor is contained in a closed rigid tank. The water is cooled to a temperature of 110°C. At this temperature the masses of saturated vapor and liquid are each 1000 kg. Determine the heat transfer for the process, in kJ.

A rigid, well-insulated tank contains a two-phase mixture consisting of 0.00014 m3 of saturated liquid water and 0.0324 m3 of saturated water vapor, initially at 101.3 kPa. A paddle wheel stirs the mixture until only saturated vapor at a higher pressure remains in the tank. Kinetic and potential energy effects are negligible. For the water, determine the amount of energy transfer by work, in kJ.

A two-phase liquid–vapor mixture of H2O, initially at 1.0 MPa with a quality of 90%, is contained in a rigid, wellinsulated tank. The mass of H2O is 2 kg. An electric resistance heater in the tank transfers energy to the water at a constant rate of 60 W for 1.95 h. Determine the final temperature of the water in the tank, in °C, and the final pressure, in bar.
