✦ Synopsis

It IS shown how one can calculate velocrty and concentratton profiles near a rotatmg dtsk takmg mto account varrable transport properties, non-zero mterfactal veloctty, and finite Schmidt number It 1s found that the surface 1s uniformly accessible for mass transfer and that the hrmtmg current, m partrcular, and heat-and mass-transfer rates, m general, are proportional to the square root of the rotation speed, other condtttons bemg the same Spectfic results are given for deposttton of copper from aqueous CuSO, soluttons, where rt 1s found that the correctton to Lev~31's classtcal equatron due to variable propertres 1s considerably greater than that due to either a non-zero mterfacial veloctty or a finite Schmidt number alone Concentratton overpotenttals are defined and calculated for copper deposttton
