The rate at which metallic ions are electroplated from a dilute electrolytic solution onto a rotating disk electrode is usually governed by the mass diffusion rate of ions to the disk. This process is believed to be controlled by the following variables:

Dimensions

k = mass-transfer coefficient……………………....…L/t

D = diffusion coefficient……………..……………...…L²/t

 d = disk diameter……………………….....………………..…L

a = angular velocity……………………….....……...…..…l/t

ρ = density………………………………………......………M/L³

μ = viscosity………………………..……………......…..…M/Lt

Obtain the set of dimensionless groups for these variables where k, μ, and D are kept in separate groups. How would you accumulate and present the experimental data for this system?
