A two phase liquid-vapor mixture of H2O is initially at 2.0 MPa with a quality of 90 %, is contained in a rigid, well insulated tank. The mass of H2O is 3 kg. An electric resistance heater in the tank transfers energy to the water at a constant rate of 60 W for 2.5 hour. Determine the final temperature of the water in the tank, in°C and the final pressure in bar.
