A 0.2 m^3tank equipped with a pressure regulator contains 4 kg saturated mixture of water at 2 MPa. The steam is now heated. The regulator keeps the steam pressure constant by letting saturated steam out. Heating is continued until all water in the tank is converted to saturated vapor.

Calculate the amount of steam that has escaped from the tank.

Calculate the amount of heat that has been transferred to the water.
