As shown in the figure, a 300-ft tank contains 25 Ib of H2O initially at 30 lbf/in?. The tank is connected to a large steam line carr steam at 200 lbf/in?, 450°F. Steam flows into the tank through a valve until the tank pressure reaches p2 = 140 Ibf/in? and the temperature is 400°F, at which time the valve is closed. Steam at 200 Ibfin 450°F Tank Valve (1) Initially: 30 Ibfin, m = 21 b (2) Finally: P, Ibfin2, 400°F

Question
As shown in the figure, a 300-ft tank contains 25 Ib of H2O initially at 30 lbf/in?. The tank is connected to a large steam line carrying steam at 200 lbf/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 Ibfin.?, 450°F Tank Valve (1) Initially: 30 Ibf in?, mi = 25 lb (2) Finally: P, Ibfin?, 400°F Determine the amount of mass that enters the tank, in Ib, and the heat transfer to the tank from its surroundings, in Btu.
