Why we use Virial Equation of State?
Since the perfect gas law is an imperfect description of a real gas, we can combine the perfect gas law and the compressibility factors of real gases to develop an equation to describe the isotherms of a real gas. This Equation is known as the Virial Equation of state, which expresses the deviation from ideality in terms of a power series in the density.
The actual behavior of fluids is often described with the virial equation:
PV = RT[1 + (B/V) + (C/(V^2)) + ...] ,
where,
B is the second virial coefficient,
C is called the third virial coefficient, etc.
in which the temperature-dependent constants for each gas are known as the virial coefficients. The second virial coefficient, B, has units of volume (L).
How to Calculate Acentric Factor using B(0) and B(1) of Pitzer Correlations for Second Virial Coefficient?
Acentric Factor using B(0) and B(1) of Pitzer Correlations for Second Virial Coefficient calculator uses Acentric Factor = (Reduced Second Virial Coefficient-Pitzer Correlations Coefficient B(0))/Pitzer Correlations Coefficient B(1) to calculate the Acentric Factor, The Acentric Factor using B(0) and B(1) of Pitzer Correlations for Second Virial Coefficient formula is defined as the ratio of the difference of reduced second virial coefficient and B(0) to the B(1), where B(0) and B(1) are functions of reduced temperature only. Acentric Factor is denoted by ω symbol.
