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?
