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.
