Abstract The authors investigate the applicability of the relationship N sh = A + B N m Re N n Sc to determine over‐all mass transfer rates in forced convection from single solid spheres, where A, B, m and n are presumed to be constants. This expression is shown to be not entirely adequate and, in particular, the changing importance of the wake with increasing Reynolds number and turbulence in the boundary layer will affect these constants.
