How does humidity affect air density
WebApr 1, 2009 · If you replace oxygen and nitrogen with water vapor, the total mass of a cubic foot of air must go down. Density is mass / volume. Thus, a decrease in mass reduces density. Adding water vapor to air (i.e., increasing humidity) decreases mass and therefore also decreases air density. Have fun. Be safe. Happy Piloting. WebNov 3, 2015 · As humidity increases pressure decreases. Since water vapor is less dense than dry air if both have the same temperature, the addition of water vapor decreases the overall density of the air and lowers its pressure.
