What Are the Limitations of Stoke's Law?

The limitations of Stoke's Law are that it only applies when the viscosity of the fluid a particle is sinking in is the predominant limitation on acceleration. This means that the particle must be relatively small and slow, so it does not cause turbulence. Its accuracy in prediction also goes down if the particle is not spherical, the fluid is compressible, the motion is constant and no other particles interfere.
