Greetings...

I want to avoid the use of psychrometric charts, but I have information of air wet and dry bulb temperature. What is the formula that will allow me to calculate the humidity, so I can then calculate the quantity of water vapor in the air. If you do not have the formula handy, at least let me know, any references where I can find it. Thanks in advance. Happy Holidays...
 
I believe using the air-water psychrometric chart would be much easier and faster than searching for the equations you speak of.

Good luck,

The equations are available from most intro thermo books.

You can also down load them from the web somewhere as an add-in to Excel.

Costs a few dollars, but if you really want. . . .
 
If you want to program it yourself, this problem was discussed before in thread724-129442
