A tank with volume equal to 0.40 m3 contains water at 160 °C and quality equal to 0.60. Water vapor is slowly drained through a valve at the top of the tank. Heat is supplied to the tank at the same time so that
the pressure in the tank remains constant. The emptying of the tank continues until the tank is filled with saturated steam at 160 °C. The effects of potential and kinetic energy can be neglected.

How much heat is added to the tank during the process?
