Berthelot equation of state

From SklogWiki

Jump to: navigation, search
RT = \left( p + \frac{a}{Tv^2} \right) \left( v - b\right)

where

a= \frac{27}{64}R^2 \frac{T_c^3}{P_c}

and

b=\frac{RT_c}{8P_c}

where p is the pressure, T is the temperature and R is the molar gas constant. Tc is the critical temperature and Pc is the pressure at the critical point.
