water than over ice at the same temperature; it is greater over a convex water surface and smaller over a concave water surface than over a plane water surface. At a temperature of 30°C the saturation vapor pressure does not exceed 42.4 millibars; at 0°C it is 6.1 millibars, and at...
Then p3 differs from the saturation pressure p of water vapour over a plane surface of the pure liquid phase at temperature T, as predicted by the generally accepted formulations, by less than ±01% of p at all temperatures between 50 and 140°C....
Example - Saturation Pressure Water Vapor 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) )...
摘要: A discussion of some of the problems involved in computing saturation vapor pressure of water for meteorological applications. Two formulations for saturation vapor pressure in the pure phase over a plane surface of water or ice are considered: the...关键词:...

16.4, the saturation vapor pressure increases nearly exponentially with temperature. This means a significant amount of product water can be removed through the gas phase via reactant flows at normal operating temperatures above 70°C. As a secondary effect, when there is a temperature gradient ...
Air saturation vapor pressure (SVP) can be calculated using different formulas, with or without over-ice correction. These different approaches result in variability that affects the simulation of surface-subsurface thermal-hydrological processes in cold regions; however, this topic has not been ...
The saturation vapor pressure of water, Ps(T) [106]. (1.22)Ps=P0exp−EvRT Boiling point is the saturation temperature. The liquid is said to be thermally saturated. A phase transition occurs when thermal energy is added. As thermal energy (heat) is removed from a vapor at saturation ...

Water vapor pressure gradient in the sand near the surface is always decreasing upward, indicating upward water vapor transport in the ground. While the downward turbulent flux of water vapor in the surface air layer over the dry ... Y Mitsuta - 《Journal of the Meteorological Society of Japa...
