A 2 m3 tank initially contains air at 100 kPa and 25 ∘C. The tank is connected to a supply line at 600 kPa and 25 ∘C. The valve is opened and air is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. A thermometer placed in the tank indicates that the air temperature at the final state is 65 ∘C. Treat air as a perfect gas. Determine the mass of air that has entered the tank. Determine the heat transfer (Q). Determine the entropy generated (Sgen).
