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
I/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?
