As shown below, a 300-ft3 tank contains H2O initially at 30 lbf/in2 and a quality of 80%. The tank is connected to a large steam line carrying steam at 200 lbf/in2, 450°F. Steam flows into the tank through a valve until the tank pressure reaches 100 Ibf/in2 and the temperature is 400°F, at which time the valve is closed. Determine the amount of mass, in lb, that enters the tank and the heat transfer between the tank and its surroundings, in Btu. (30 pts) 3.
