stokes and poise

Stokes are the way kinematic viscosity is measured and basically measures how fast a steel ball bearing falls through a solution. Poise is a measure of the internal resistance of a liquid and basically tells us how fast it flows . The difference between Stokes and Poise is that Stokes is Poise divided by the specific gravity of the liquid.
