Psychrometric Chart for Nitrogen - Methanol Mixtures

Bring the power of psychrometric calculations to nonaqueous gas-solvent mixtures.  The Akton Psychrometric Chart provides for the user to change the constants within the Function Library (PFL) and allows the user to construct a chart for Gas/Solvent Mixtures rather than Air/Water.
