Comments |
The Beattie-Bridgeman equation of state is an attempt to more accurately model real gases by going beyond the ideal gas equation. With knowledge of the three empirical constants (different for each gas) the Beattie-Bridgeman equation of state can be used to give accurate predictions of behaviour of gases. |
