A large compressed air storage tank with a volume of 100 m3is initially at 200 kPa and 288 K. The supply line valve is opened allowing a constant mass flowrate into the tank of 0.25 kg/s. When the tank pressure reaches 800 kPa the valve is closed. The supply line to the tank is regulated to 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 from the class equation sheet at 300 K.
Assume the filling process is so slow that the tank air temperature remains constant at 288 K. Find the mass added to the tank and the elapsed time.

Repeat For a large STEAM storage tank with a volume of 100 m3 initially at 3.0 bar and 200 oC. The STEAM supply line valve is opened allowing a constant mass flowrate into the tank of 0.25 kg/s. When the tank pressure reaches 10 bar the valve is closed. The supply line to the tank is regulated to maintain a pressure of 20 bar and a temperature of 240 oC. The fluid kinetic and potential energies and the mass of the tank itself are insignificant.
