Saturation
Vapor Pressure
¥The partial vapor pressure at which the
rate of evaporation
equals the rate of condensation in a closed system
is called the saturation vapor pressure or SVP.
The SVP effectively denotes the maximum water
vapor that air the can ÒholdÓ.
¥SVP depends strongly on temperature.
¥Vapor pressure and SVP provide a measure of
the actual water
vapor content and the airÕs potential capacity,
respectively.
