[Equest-users] Evaporative cooling

[sambhav tiwari]

Hi All,
          I wanted to know the temperature and mositure content kg
moisture/kg dry air of air leaving the evaporative cooler for a
particular hour.

Now by  the relation  Ti  =Td-(Td-Tw)XE

Ti is temp of air leaving cooler

Td and Tw are dry and wet bulb temperatures for that hour from weather file.

E is efficiency of cooler from 0.8 to 0.9

from above relation i can find temp of air leaving cooler but how can
i find moisture content of air leaving cooler ?i have outside air RH
from weather file for that hour


Thanks
Sambhav
