This table gives the approximate relative humidity directly from the reading of the air temperature (dry bulb) and the wet bulb. It is computed for a pressure of 74.27 cm Hg.
To determine percent of relative humidity, first determine the dry bulb temperature and then the depression. The intersection of both columns is the percent of relative humidity.
Find this number—the difference in degrees—at the top of the chart and place your fi nger on it. Find the dry-bulb temperature in the fi rst column on the left. Place your fi nger on it. Bring your fi ngers down …
