I am trying to figure out this problem - maybe it is simple for someone of you but I can't figure it out.
I have known variables of outside air temperature and relative humidity (RH), I am taking that air into the heater and have two fans that pump 640,000 m$^3$ per hour. The air is being heated up to 80 degrees Celsius.
My question is how can I calculate the RH of the heated air and is there any corelations between how much air is being pumped and how much can that air take RH from grain that I am trying to dry?
In short two fans with capacity of 640,000 m$^3$ per hour, 100 tons of grain, how to calculate best way and how much air does it need to dry it?
