Wohl equation of state

The Wohl equation of state is given by \[\left[ p + \frac{a}{Tv(v-b)} - \frac{c}{T^2v^3} \right] (v-b) = RT\]

where (Eq. 10 in ):

\[\left. a \right.= 6P_cT_cv_c^2\]

\[b= \frac{v_c}{4}\]

and

\[\left. c \right. = 4P_cT_c^2v_c^3\]

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.
