During sensible heating of air Relative humidity decreases.
What happens during sensible heating of air?
In sensible heating process the temperature of air is increased without changing its moisture content. During this process the sensible heat, DB and WB temperature of the air increases while latent of air, and the DP point temperature of the air remains constant.
Why does RH decrease during sensible air heat?
The reason is that the same amount of water vapor remains in the air but at a higher temperature, its vapor pressure (which is related to the maximum amount of water that air at that temperature can hold) increases.
