THE PSYCHROMETRIC CHART
The psychrometric chart is a graphical representation of the thermodynamic properties of moist air. It describes all the possible combinations of temperature, moisture content, density and energy relating to air at one time. The usefulness of the psychrometric chart can be seen in that given any two properties of air, the remaining properties can be determined graphically. It should be noted that psychrometric charts do differ with respect to altitude (i.e. barometric pressure). Below is an illustration of a psychrometric chart which is followed by explanations of the terminology related to its properties.
