Title of the articleDiffusion of vapors of aqueous solutions
Abstract.Problem statememt. The aim of this work is to obtain experimental values of the diffusion coefficient of the vapor of aqueous solutions and their comparison with possible obtained by different semiempirical methods. Results. As a result of the study, we found significant discrepancies between the values defined both theoretically and experimentally, between the experimental results obtained by different methods. Even semi-empirical formula in which the coefficients of diffusion have comparable physical sense, lead to differences. Conclusions. The significance of the results for the construction industry lies in the experimental determination of diffusion coefficients of water vapor and aqueous ammonium at different concentrations based on the implementation of the method of Stephen.
Keywords.the diffusion coefficient, diffusion tube, the criterion of dependence, evaporation, heat.
