What is the standard atmospheric pressure in the psychrometric chart? This can be accomplished through use of psychrometric tables or a psychrometric chart.
In broader terms it is the science and practices associated with atmospheric air mixtures, their control, and the effect on materials and human comfort. Psychrometry is an impressive word which is defined as the measurement of the moisture content of air.

THE USE OF THE PSYCHROMETRIC TABLE The psychrometric properties in Table 54T03 have been compiled through countless laboratory experiments and mathematical calculations and are the basis for what we know as the psychrometric chart. Humid - How were the psychrometric properties in table 54t03 compiled? Locate the ‘humidity ratio’ along the right vertical axis. This scale will be in degrees F or degrees C.
Locate the dry bulb tem - perature along the bottom axis and the associated vertical line for each temperature.
