Equations of state for the square well model. From the continuous pressure equation one can arrive at the following discontinuous equation for the square well model (Eq. 7b [1])
![{\displaystyle Z={\frac {pV}{Nk_{B}T}}=1+{\frac {2\pi }{3}}\rho \sigma ^{3}\left({\rm {g}}(\sigma ^{+})-\lambda ^{3}\left[{\rm {g}}(\lambda \sigma ^{-})-{\rm {g}}(\lambda \sigma ^{+})\right]\right)}](https://wikimedia.org/api/rest_v1/media/math/render/svg/668d2766ecc8d2de7549a7ab8eebc69747a2e1c1)
