As shown in the figure, a 320-ft³ tank contains 25 lb of H₂O initially at 30 lbf/in². 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 = 160 lbf/in² and the temperature is 400°F, at which time the valve is closed. Steam at 200 lbf/in.2 450°F Valve A (1) Tank Initially: 30 lbfin.², m₁ = 25 lb (2) Finally: P₂ lbfin.², 400°F. Determine the amount of mass that enters the tank, in lb, and the heat transfer to the tank from its surroundings, in Btu.
