van der Waals equation

n.
An equation of state that relates the pressure, volume, and absolute temperature of a gas taking into account the finite size of molecules, and their intermolecular attraction, having the form RT = (P + av-2)(v - b), where R is the gas constant, T is the absolute temperature, P is the pressure, v is the volume, and a and b are constants.

[After Johannes Diderik van der Waals.]

This is true for SRK and PR, but not for the van der Waals equation of state, which has the constants [[DELTA].sub.1] = [[DELTA].sub.2] = 0.
With this background, we proceed to explore the implications of the van der Waals equation of state.
As mentioned previously, the 2-domain Tait equation and the Van Der Waals equation of state were the equations chosen in this work for the polymer and gas, respectively.
The simplest choice is, of course, the van der Waals equation of state given by:
