Dieterici equation of state
where (Eq. 8 in ):
Sadus  proposed replacing the repulsive section of the Dieterici equation with the Carnahan-Starling equation of state, which is often used to describe the equation of state of the hard sphere model, resulting in (Eq. 5):
where is the packing fraction.
This equation gives:
