A compressed air storage cylinder has a volume of 0.5m^3 and contains
air at an absolute pressure of 1.8MPa and temperature 20°C. A
quantity of the air is released during which the temperature of the
remaining air falls to 15°C and the pressure to 1.5MPa. Calculate the
mass of the air released. The characteristic gas constant for air is
287Jkg−1K^−1.
