Allows you to calculate the fugacity from a single component (pure) or mixture, using any of the following state equations: "virial", "Van der Waals", "Redlich-Kwong", "Redlich-Kwong-Soave", "Peng-Robinson". Also allows you to calculate the activity coefficient, using "Margules", "Van Laar", "Wilson", "UNIQUAC", "UNIFAC". ("Infinite dilution activity coefficients" method). |
