Baonza equation of state

Baonza, et al formulated an equation based on a linear bulk modulus called the Baonza equation of state. It has a simple analytical form but also gives similar accuracy to the Rose-Vinet (Universal) equation of state. The equation of state is:

$p={\frac {\gamma B_{0}}{B_{0}'}}\left[\left(1+B_{0}'\left({\frac {1}{\gamma }}-1\right)ln\left({\frac {V_{0}}{V}}\right)\right)^{1/(1-\gamma )}-1\right]$

where $B_{0}$ is the isothermal bulk modulus, $B_{0}'$ is the pressure derivative of the bulk modulus and $\gamma$ relates the bulk modulus and its pressure derivative via:

$B=B_{0}\left(1+{\frac {B_{0}'}{B_{0}}}P\right)^{\gamma }$
