American Society of Heating and Ventilating Engineers Guide, 1936 Since the difference in vapor pressures is substantially proportional to the difference between the wet- and dry-bulb temperatures the wet- bulb depression) the rate of evaporation is also, for case two, substantially proportionate to the wet-bulb depression.

American Society of Heating and Ventilating Engineers Guide, 1936 Definition of Effective Temperature Briefly, effective temperature may be defined as an arbitrary index of the degree of warmth or cold felt by the human body in response to tempera ture, humidity, and movement of the air.
