The psychrometer consists of two accurate thermometers. On the bulb of one is a wick which dips in a cup of distilled water. When the air is saturated it has all the water it will hold. If the air is not saturated, water will evaporate from the wick, and the dryer the air the greater the evaporation. As the water passes from around the bulb into the air it lowers the temperature. The thermometer should be fanned briskly with a good fan for three minutes, and then the reading taken quickly. First find the dry-bulb reading on the chart and then the wet-bulb reading in the next column; in the third column, opposite the.
