How much condensate when 90F 80%RH air dropped to 40F?
(OP)
Per cubic foot of hot 90F humid 80%RH air, how much water is released when that air temp is dropped to 40F?
Thank you for any comments.

To a ChE, the glass is always full - 1/2 air and 1/2 water.

where I took the water content of 90F 80%RH air and subtracted water content of 40F 100%RH air.
Not sure if correct, yet, double checking it...

The chart I gave a link to has an error in their moisture content numbers. It should be lb/lb dry air for the numbers I used, not Grains/lb of dry air. My redo is:
About 0.0246 - 0.0052 = 0.0194 lbs H2O/lbs dry air. The 90F/80%RH air is 14.4 ft3/lb of dry air. So, 0.00135 lbs H2O/ft3 of dry air, and 0.0216 oz H2O/ft3 of dry air.
Both our numbers round to 0.022 oz/ft3 of dry air.
You are good to go!

Quite handy just to plug in and pull the values off
