A 3 m' tank initially contains air at 100 kPa and 25°C. The tank is connected to a supply line at 550 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. Treating air as a perfect gas, determine (a) the mass of air that has entered the tank, (b) the heat transfer (Q) and (c) the entropy generated (Spen). Supply line Air
