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.
