Open publisher page 0 citations

Abstract

Combined with biocomponent gas diffusion principle,a simple method for diffusion coefficient determination by evaporating tube is proposed under the assumption of steady diffusion and material balance calculation method.Various factors influencing the method were discussed.The optimum conditions are at temperature T330 K,diffusion time θ5 h and diffusion distance z080 mm.The diffusion coefficient of the air-H2O system is determined,and the experimental results are consistent with the documented value.
