A200-l tank (see fig. p4.107) initially contains water at 100 kpa and a quality of 1%. heat is transferred to the water, thereby raising its pressure and temperature. at a pressure of 2 mpa, a safety valve opens and saturated vapor at 2 mpa flows out. the process continues, maintaining 2 mpa inside until the quality in the tank is 90%, then stops. determine the total mass of water that flowed out and the total heat transfer.
