t = Celsius temperature, based on thermodynamic temperature scale and expressed relative to absolute temperature T in kelvins (K) by the following relation: Ws = humidity ratio at saturation, condition at which gaseous phase (moist air) exists in equilibrium with condensed phase (liquid or solid) at given temperature and pressure (standard READING PSYCHROMETRIC CHART To the novice, a psychrometric chart seems a dizzying maze of lines and curves going every which way, but once a few fundamental things are understood about the psych chart, it is not really that difficult to understand. If we dissect the components piece by piece, the usefulness of the chart will be clearer.

standard psychrometric chart (Fig. 35). The dry-bulb, wet-bulb, and dewpoint temperatures and the relative humidity are so inter-related that, if two properties are known, all other properties shown may be determined. When air is saturated, dry-bulb, wet-bulb, and dewpoint temperatures are all equal. THE PSYCHROMETRIC CHART: Theory and Application Perry Peralta NC State University.

While the charts may look complex, they’re relatively easy to read when you know what each part of the graph is representing. By identifying the axes and reading the markings on the interior of the chart, you can plot points and draw conclusions from known measurements on the chart.
