Extracted text: A 12 ft^3 rigid tank initially contains saturated water vapor at 250 F. The tank is connected by a valve to a supply line that carries steam at 160 psia and 400 F. Now the valve is opened, and steam is allowed to enter the tank. Heat transfer takes place with the surrounds such that the temperature in the tank remains constant at 250 F at all times. The valve is closed when one-half of the volume of the tank is occupied by liquid water. Initially the tank contained 0.86856 Ibm of water (vapor) and at the final state the tank contained 353.38 lbm of water (liquid/vapor mixture). The mass of steam that came in the tank is 352.51 Ibm. The quality at the final state is 0.001229. What is the heat transfer out of the tank in units of Btu? Select the answer that is closest to the true value. A) 176,300 B) 235,000 C) 294,000 D) 353,000 O A OD
