Oh, so it’s not a linear relationship. Good to know. What about as air drops below freezing to -10 or -20?

Ok, so air only changes 3.3% for every 10 deg C. That’s great. I would call that statistically insignificant so I can ignore it. the rule of thumb that I guess I was referring to was that humidity drops roughly in half (assuming no additions or removal of water) for ever 10 deg C increase in...

Ok i got it. First you must use this formula to find the saturation pressure at the given temperature. Saturation vapour pressure, ps, in pascals: ps = 610.78 *exp( t / ( t + 238.3 ) *17.2694 ) where t is the temperature in degrees Celsius At 18 deg C it = 2054 Pa Relative Humidity (RH) =...

Thx haruspex, I’ve been continuing my research on my own and it seems to always come back to plotting points on a psychometric table. But I am trying to design a computer model that can take the units expressed and convert it to lbs of water/hr removed which can then be calculated against the...

This is not homework, this is a farmer trying to dry grain in his bin properly.

No, I have not found the right formula yet.

MOD Note: Moved from Member intros to here hence no homework template. While its not homework it fits the spirit of homework. If ambient air is 10 deg C with relative humidity of 75%. And air exiting a grain bin is 18 deg C with relative humidity of 85% at a rate of 3000 cubic feet per second...
