Page 58 - This buIb is cooled by the evaporation, the rate of which, and hence the resultant cooling, depends in a definite manner upon the relative humidity of the air. The dew point is the temperature at which the air becomes "saturated" with water vapor, so that the relative humidity is 100%. It is the temperature at which the maximum saturation vapor pressure of water would be equal to the actual partial pressure of the water vapor in the atmosphere. At the dew point, wet-and-dry-buIb thermometers read...
