Compressibility Factors Using the Soave-Redlich-Kwong Equation of State
The Soave–Redlich–Kwong equation of state can accurately describe a compound in both liquid and vapor phases. This Demonstration applies this equation of state to estimate and plot the compressibility factor, , versus reduced pressure, =, for ethane at various values of the reduced temperature, =.
