A large compressed air storage tank with volume of 100 m^3 is initially at 200 kPa and 288 K. The supply line valve is opened allowing a constant mass flow-rate into the tank of .25 kg/s. When the tank pressure reaches 800 kPa the valve is closed. The supply line to the tank is regulated tot maintain a pressure of 900 kPa and a temperature of 313 K. The fluid kinetic and potential energies and the mass of the tank itself are insignificant. Use AIR property values at 300 K. Assume the filling process is so slow that the tank air temperature remains constant at 288 K. (Q cannot equal 0) Find the mass added to the tank and the elapsed time.
