I understand that exhaust temperature is 290F = 143.333C and Relative humidity is around %100. Relative Humidity, RH = Pw/Pws and Pw = pressure of water vapor in the air , and Pws= pressure of saturated vapor(steam) . RH=100 means that Pw=Pws and Pws at this temperature vapor...
Dear Ovenguy
Two major factors affect energy balance of your case, Volume of exhaust and temperature of it.
The amount of moisture which air can hold depends on pressure and temperature.
If exhaust directly vented to atmosphere, then pressure is determined by elevation above sea level of the...
