An insulated 1.7 m3 rigid tank contains air at 500 kPa and 50oC. A valve connected to the tank is now opened and air is allowed to escape until the pressure inside drops to 200 kPa. The air temperature during this process is maintained constant by an electric resistance heater placed in the tank. a. Determine the mass of air initially, m1 in kg. b. How much air escaped from the tank, mout in kg. c. Determine the electrical work...

A 2.2-m3 rigid tank initially contains air at 100 kPa and 22°C. The tank is connected to a supply line through a valve. Air is flowing in the supply line at 600 kPa and 22°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...
