Dear bzeng

You should use Psychometric Charts to find (kg H2O)/ (kg Air), you can determine this ratio by 2 known parameter of "[B]Dry Bulb Temp, Wet Bulb Temp, Relative Humidity, Humidity Ratio and Enthalpy[/B]". The below site explains how to obtain the desired parameter from psychometric charts:

Then go to the composition tab in HYSYS and change basis into "Mass Fraction" and enter the proper fraction which obtained from the charts or software.

Good Luck
