Question: Steam at 200 psia, 60WF is flowing in a pipe. Connected to this pipe through a valve is an evacuated tank. The valve is suddenly opened and the tank fills with steam until the pressure is 200 psia and the valve is closed. If the whole process is insulated (no heat transfer) and K and fare negligible, determine the final internal energy of the steam.
