As shown in the figure, a 300-ft³ tank contains 25 lb of H20 initially at 30 lbf/in². The tank is connected to a large steam line carrying steam at 200 Ibf/in?, 450°F. Steam flows into the tank through a valve until the tank pressure reaches p2 = 140 lbf/in? and the temperature is 400°F, at which time the valve is closed. Steam at 200 lbf/in.², 450°F Tank Valve |(1) Initially: 30 lbfin.?, mị = 25 lb (2) Finally: P, lbfin.?, 400ºF. Determine the amount of mass that enters the tank, in Ib, and the heat transfer to the tank from its surroundings, in Btu.
