Wohl equation of state: Difference between revisions

The Wohl equation of state is given by^[1]

\left[p+{\frac {a}{Tv(v-b)}}-{\frac {c}{T^{2}v^{3}}}\right](v-b)=RT

where (Eq. 10 in ^[2]):

\left.a\right.=6P_{c}T_{c}v_{c}^{2}

b={\frac {v_{c}}{4}}

and

\left.c\right.=4P_{c}T_{c}^{2}v_{c}^{3}

where $p$ is the pressure, $T$ is the temperature and $R$ is the molar gas constant. $T_{c}$ is the critical temperature and $P_{c}$ is the pressure at the critical point.
