## Psychrometric Chart

The psychrometric chart gives the relative humidity for a given wet-bulb and dry-bulb temperature.
To use, find the vertical line for the dry bulb temperature at the bottom of the chart, and
the slanted line for the wet-bulb temperature at the curved top-left edge. Find the intersection
point of these two lines, and read the percent relative humidity from the curved lines nearest that
point.
