REAL GAS VOLUMES
|
| The gas volumes were derived from the Beattie-Bridgeman equation of state for real gases at 20 degC.
For comparison purposes a set of double 104's have an internal volume of approximately 1.2 cubic feet. |
| Volumetric Compressibility of Real Gases |
Standard Cubic Feet (scf) of gas compressed into a 1 ft3 container
at the given pressure and a temperature of 20oC. |
