WebHumidity Ratio (W) is the weight (lbs) of water vapor per unit weight (1 lb) of dry air. It is the moisture content of the air and it is indicative of the latent heat content of the air. Saturated Air contains the maximum possible moisture (water vapor or steam) that the air can hold at a given DB temp. Weborder to change the relative humidity of air, even at a constant temperature. This is relevant to conservators. The transfer of heat from an air stream to a wet surface, which releases water vapour to the air stream at the same time as it cools it, is the basis for psychrometry and many other microclimatic phenomena.

WebMay 27, 2015 · In psychrometrics, we care mainly about the yellow region and what happens at the boundary between the vapor phase and the liquid or solid phases. That boundary in the pressure-temperature diagram is the same boundary you see in the psychrometric chart. It’s the 100% relative humidity curve, also known as the saturation curve.
