When the water vapor in the air reaches saturation, the excess water vapor condenses and combines with tiny dust particles to form small water droplets or ice crystals, namely, the “fog”. Current researches i
The Saturation pressure of water vapor in moist air at dry bulb temperature25oCcan be calculated: First, convertion from °C to K: (25 °C) + 273 = 298 (K) Then Eq. (1) is used: pws= e(77.3450 + 0.0057 (298 K) - 7235 / (298 K))/ 298 (K)8.2 ...
water vapordehydrationThe goal of this investigation is to understand the mechanism behind the observed high relative humidity with respect to ice (RHi) in the tropical region between ~14 km (150 hPa) and the tropopause, often referred to as the tropical tropopause layer (TTL). As shown by...
In analyses of certain nucleation problems in cloud physics, estimates of the saturation vapor pressure over water at very large degrees of supercooling are needed. For example, since nucleation of a liquid phase from a supersaturated vapor phase is thermodynamically more probable than nucleation of ...
Pw = saturation water vapor pressure at water temperature, tw (kPa); Pa = partial water vapor pressure in the air (kPa); and v0.3 = wind speed velocity at a height of 0.3 m above the pool (m/s). If the wind velocity above the pool cannot be measured, it can be obtained from cl...
However, I couldbring the water vapor to saturationeitherby adding water vaporto that chamber in some way orby cooling it. In any case I can approach the saturation curve. And when I get there, whether it's there or there, doesn't matter, therelative humidity will be 100%. And if I...
Of course, if there was air there, the total pressure would be higher, but the partial pressure would be--of water vapor would be the same value here. The vapor pressure is what you have. Depends on how much water vapor you have and its temperature. But the saturation is the value ...

In the atmospheric condition, there always exists an equilibrium level of water vapor in the air due to the water evaporation process. The behavior of water existing in the form of gas molecules can be mathematically described by an ideal gas law defined as (3.1)p·V=n·R·T where p is...
