Variations in apparent weight may occur due to variations in the room temperature and to electrical charges. Small variations in temperature of the evaporating liquid have a very strong influence, especially at higher evaporation rates. The diffusion coefficient of water vapor in air is determined ...
Re: Diffusion Coefficient of water vapor in a gas mixture «Reply #1 on:July 01, 2019, 10:20:16 AM » Your gas mixture is basically air, and you can find experimental diffusion constants for water vapor in air at different temperatures: e.g.,https://www.engineeringtoolbox.com/air-...

the oxygen volume fraction in air is assumed to be 0.1 at the outlet. The gas at thecathode sideis further diluted, due to thewater vaporand itssaturation pressure.Table 2.6lists the resulting values ofjlimfor both scenarios. The full calculation is summarized in the framed box at the end...
The air inside the cooling tower is heated and lifted naturally, with a large amount of water vapor entrained in the air, forming a wet heat plume discharged from the top of the cooling tower. The particle size of the droplets in the wet plume is about 10–1000 μm, due to the small...
The asymptote of the curve intersects the time axis at a point whose position serves to determine the diffusion coefficient, by applying an equation derived from the formula given by Carslaw and Jaeger. The coefficients thus determined for the three rare gases in runs at temperatures between ...
coefficient of water vapor diffusion in wood, which can be derived from the coefficient ofinterdiffusionof water vapor in air, increases rapidly with increase in temperature due to the temperature dependence of the vapor pressure. As moisture content increases, the water vapor diffusion coefficient ...
