Beattie-Bridgeman equation of state: Difference between revisions

Latest revision as of 17:24, 6 February 2008

The Beattie-Bridgeman equation of state is given by (Ref. 1 Eq. 1)

p={\frac {RT(1-\epsilon )}{v^{2}}}(v+B)-{\frac {A}{v^{2}}}

where

A=A_{0}\left(1-{\frac {a}{v}}\right)

B=B_{0}\left(1-{\frac {b}{v}}\right)

and

\epsilon ={\frac {c}{vT^{3}}}

where $p$ is the pressure, $T$ is the temperature and $R$ is the molar gas constant.
