Abstract
On the basis of the model suggested in this paper an expression for the coefficient of mass transfer from a solid particle suspended in a turbulent flow of liquid β = Q.261ScL -3/4 (EvL)1/4 has been obtained theoretically. It is in good agreement with experimental data. The dissolution kinetics of particles is analytically described and a common procedure for calculating the dissolution of solids with arbitrary size distribution in stirred vessels has been developed on the basis of these results. The calculation results are compared with the experimental data obtained in vessels of different diameter with and without baffles.Keywords
