Consider a process in which metal ions in the electrolyte solution are plated on a rotary diskshaped electrode. The plating rate depends on the rate at which metal ions diffuse to the surface of the rotary disk. This process is affected by the process variables below. Use dimensional analysis to express the relationship between the dimensionless numbers
groups
The dimensional analysis problem is for six given process variables. There are no other process variables. Therefore, it is the dimensionless number that subtracts the number of basic dimensions from
here.
Process variables and units
k: mass transfer coefficient ms
D: Diffusion coefficient
: the radius of a disk m
: the rotational angular
velocity of a disk
: density of electrolytes
viscosity of electrolyte
