Various methods have been discussed of experimental measurement of interfacial mass transfer under the turbulent flow in a tube at high values of the Schmidt number. Difficulties and shortcomings have been discussed of the determination of the mass transfer coefficient k+, i.e. the quantity necessary for experimental verification of theoretical models. Necessity has been stressed of devising special experiments to further elucidate the mechanism of interfacial heat and mass transfer in the turbulent flow.
