As shown in the figure, a 280-ft³ tank contains 25 lb of H2O initially at 30 lbf/in?. 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 p2 = 100 lbf/in² and the temperature is 400°F, at which time the valve is closed. Steam at Tank 200 lbf/in_2. Valve |(1) Intially: 30 lbfin.?, mị = 25 lb |(2) Finally: P, lbfin.?, 400°F. 450°F Determine the amount of mass that enters the tank, in Ib, and the heat transfer to the tank from its surroundings, in Btu.
