WebModelling of high-pressure phase equilibria using the Sako–Wu–Prausnitz equation of state. Fluid Phase Equilibria 1999, 163 (1) , 79-98. DOI: 10.1016/S0378-3812(99)00220-4. … WebThe equation of state is the function that relates the pressure to the density, molecular weight, and temperature at any place in the star. Since it is a solely an internal property of the gas, it can, in principle, be computed once externally, and used via a lookup table, i.e., P = P(ρ,µ,T). The net pressure can be divided into three ...

WebUpon extension to mixtures, the equation of state is used to calculate high-pressure phase equilibria for the ethylene–polyethylene system. The relatively simple equation may be useful for engineering-design calculations for fluid mixtures containg polymers, especially when very few experimental data are available.
