Concept:

Psychrometry is the study of the properties of mixtures of air and water vapor. 

Every psychometric chart includes

  • Vertical lines that represent the dry bulb temperatures,
  • The diagonal line represents the wet-bulb temperature
  • Curved lines represent relative humidity.

Dry Bulb Temperature: Actual temperature of gas or mixture of gases

Wet Bulb temperature: Temperature obtained by an accurate thermometer having a wick moistened with distilled water

Dew point temperature: Temperature at which the liquid droplets just appear when the moist air is cooled continuously.
