Answer to Question #75147 in Mechanical Engineering for Ryan
A compressed air storage cylinder has a volume of 1 m3 and contains air at an absolute pressure of 2 MPa and temperature 25°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 MPa. The characteristic gas constant for air is 287 Jkg−1K−1.
Calculate the mass of the air released.
