A 3 m³ tank initially contains a mixture of saturated steam and saturated liquid at 3400 kPa. Of the total mass, 15% is steam. Saturated liquid is poured from the tank through a valve located at the bottom of the tank, until the total mass in the tank is equal to 40% of the initial total mass. If during the process the temperature of the tank is kept constant, how much heat has been added?
