A 130 L rigid tank initially contains nitrogen at 400 kPa, 100 K. Thetank is connected to a line which contains nitrogen at 10,000 kPa, 260 K.The valve is opened and nitrogen flows into the tank until half of thetank’s volume is filled with liquid nitrogen, at which point the valve isclosed. During the filling process heat is transferred from the tank tokeep the temperature constant at 100 K.

1. An insulated cylindrical storage tank of 80 m’volume initially contains 75 m'of nonvolatile liquid and 5m'of air at 100 kPa and 300 K. Solubility of air in the liquid is negligible. It is proposed to transfer this liquid to another storage tank by pressurizing the tank with air from a supply line at 3MPA and 300 K. For this purpose, first air is admitted into the tank, while the exit valve is kept closed, until the pressure in the tank reaches 3MPA. Then the exit valve is opened slightly to transfer the liquid while keeping the pressure constant at 3MPA. Calculate the temperature in the tank when it is completely filled withair. 2.
