✦ Synopsis
The applicability of Kolmogoroff s theory of local isotropic turbulence to problems involving particb-liquid mass transfer in turbulent flow is critically examined. With certain assumptions this theory leads to the conclusion that the hydrodynamics of mass transfer can be accounted for by a single parameter; the power input per unit mass. Evidence is presented from the literature to show that Power input oer unit mass is not a successful method of correlating mass transfer rates to particles suspended inagitated vessels.
