The mass transfer at a rotating-disk electrode with an external forced convection has been studied in this paper. The mass-transfer factor of the forced-convective rotating disk suitable for Schmidt numbers greater than 1 is presented. The limiting currents of the ferricyanide reduction at various forced-flow strength and rotating speeds were measured experimentally and used to estimate the mass transfer at the forced-convective rotating disk. It is found that the experimental results agree very well with the values calculated theoretically
