Method of Determining Diffusion Coefficient from the Kinetics of Evaporation in a Closed Vessel.

In studying stationary and dynamic mass-exchange processes, determination of the values of diffusion coefficients is important. Among tthe methods of determination of diffusion coefficients the method of A. S. Irisov based on the kinetics of isothermal evaporation in a closed vessel is widely applied. The article analyzes ths method and on the basis of the Fick equation for the case of isothermal evaporation in a closed cylindrical vessel, the method of processing experimental data is made more precise, thus making it possible to obtain more reliable results.
