Stoke's Law

Stoke's Equation: The velocity at which a fat globule will rise or fall in a liquid varies as the square of its diameter:

V is equal to {d(squared) x (pd-pc) x ra(Squared)} / 18n

Where :
  • V =particle velocity
  • d=particle diameter
  • pd=discrete phase density
  • pc=continuous phase density
  • r=radius of axis of rotation
  • a=angular velocity
  • n=continuous phase velocity
note : (r (a Sqared)) is replaced by g (the force of gravity) when not in a centrifugal field
For example, a fat globule with a diameter of 2 microns will rise 4 times faster than a fat globule with a diameter of 1 micron.
