Cole equation of state

An equation of state introduced by R. H. Cole^[1][2][3]

${\displaystyle p=B\left[\left({\frac {\rho }{\rho _{0}}}\right)^{\gamma }-1\right],}$

where ${\displaystyle \rho _{0}}$ is a reference density, ${\displaystyle \gamma }$ is the adiabatic index, and ${\displaystyle B}$ is a parameter with pressure units.^[4]
