Effective Temperature
</dt>
1. In astrophysics, a measure of the temperature of a star deduced by
means of the Stefan-Boltzmann
law, from the total energy emitted per unit area. Compare brightness
temperature, color
temperature.
</dd>
Effective temperature is always less than actual temperature.

2. In physiology, the temperature at which motionless, saturated air would
induce, in a sedentary worker wearing ordinary indoor clothing, the same
sensation of comfort as that induced by the actual conditions of temperature,
humidity, and air movement. Compare sensible
temperature, standard operative temperature, operative
temperature.
</dd>
Effective temperature is used as a guide in air-conditioning practice,
and, on the comfort chart (American Society of Heating and Air Conditioning
Engineers) it appears as a family of curves which serves as one coordinate in
defining comfort zones. [[/a>|/a>
