Psychrometrics

"Psychrometrics is the study of the physical and thermal properties of air and water vapor mixtures (Henderson et al., 1993)." Atmospheric air contains water vapor, pollutants, and gases, such as nitrogen, oxygen, carbon dioxide, etc. Dry air is referred to as air devoid of water vapor and pollutants. The mixture of dry air and water vapor, called moist air, is the basis for psychrometric analysis. A solid understanding of the physical and thermal properties of moist air is the foundation for conceptual and design analyses of industrial drying, heating and cooling processes".
