The temperature range for use is also given in the columns (TMIN and TMAX). The equation should not be used for temperatures outside this range. The next column provides the code for the tabulation. The last three columns provide values for diffusion coefficient in air at representative ...
A comparison of the absorption spectra of the fluorobenzenes and benzene in the region 4.5-9.5 eV The gas-phase extinction-coefficient spectra of ten fluorosubstituted benzenes are presented and compared with benzene in the region 4.5-9.5 eV. The three ... J Philis,A Bolovinos,G Andritsopoul...
during a certain time interval (t) in a medium whose coefficient of diffusion (D) is known,Dbeing equal to one-half the average of the square of thedisplacementin thex-direction. This formula for probability “density” allowsPto be plotted againstx. The graph is the familiarbell-shaped ...

(1998). The influence of air temperature on effective diffusion coefficient of moisture in the falling rate period. Drying Technology, 16(7), 1487-1499.Sander, A.; Tomas, S.; Skansi, D. The influence of air temperature on effective diffusion coefficient of moisture in the falling rate ...
In subject area: Engineering The Darcy permeability is similar to the diffusion coefficient, which represents the viscous resistance of a solid material to fluid flow under a pressure gradient, and is related to the microstructure of the solid skeleton and the viscosity of the fluid. ...
Activity coefficient data are used to calculate resistance coefficients from the diffusion results. For aqueous sodium decanoate, micellar aggregation produces a 4-fold decrease in the friction acting on the diffusing salt. The mutual diffusion coefficient of aqueous sodium octanoate is compared with ...
The transport of gaseous compounds in soil takes place by gas diffusion, advection, and dispersion. Gas transport processes are influenced by the soil-gas diffusion coefficient (Dp), air permeability (ka) and soil-gas dispersion coefficient (DH), respectively. Of three gas transport parameters, DH...
The nitrite mass was converted to ambient concentration of NO2 using the diffusion coefficient for NO2 in air, the internal length and cross-sectional area of the tube, and the exposure time (Targa and Loader, 2008). The nitrite mass collected by Ogawa[S] samplers and calculation of ambient...
The coefficient of water vapor diffusion in wood, which can be derived from the coefficient of interdiffusion of 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 ...
