How to Determine Relative Humidity From a Wet & Dry Bulb ... - Sciencing

Prototype hygrometers were devised and developed during the Shang dynasty in Ancient China to study weather. The Chinese used a bar of charcoal and a lump of earth: its dry weight was taken, then compared with its damp weight after being exposed in the air. The differences in weight were used to tally the humidity level. Webb…two thermometers—one wet-bulb and one dry-bulb—to determine humidity through evaporation. A wetted cloth wraps the wet-bulb thermometer at its enlarged end. By rapidly rotating both thermometers, or by blowing air over the bulbs, the temperature of the wet-bulb thermometer is cooler than that of the dry-bulb thermometer. The difference in… slam affective disorders service
