A combination of classical thermodynamics and molecular theory was used to calculate the enhancement factor (ratio of vapor-phase partial pressure to saturated vapor pressure) for liquid mercury in equilibrium with air at standard atmospheric pressure at temperatures from 0 °C to 40 °C. The enhanc...

That's a low enough pressure that the water vapor will be nearly ideal, so we can also take that as the fugacity (If I wanted to be more rigorous, I could use REFPROP to calculate the fugacity of the pure water). For the vapor phase, the calculation of that mixture in REFPROP at ...
, the water-vapor/air mixture is produced by mixing metered streams of moist air produced by the two-pressure principle with purified, dry air; here, the HHG saturates the wet air stream at a temperature close to the water triple point, reducing the uncertainty of the water vapor pressure....
