4006 -- Simplified Relationships for the Enhancement and Compressibility Factors of Moist Air PDF

The adoption of an ideal mixture model greatly simplifies the calculation of the thermodynamic properties of moist air. The real mixture model provides more accuracy; however, it is necessary to introduce moist air enhancement and compressibility factors, which can both prove to be difficult to evaluate. Presents a number of approximate relationships for these parameters that are valid for an extended thermodynamic range (from 0.1MPa to 5.0MPa and from -100degC to 200degC).
