RE: Dynamic/Kinematic Viscosity
Kinematic Viscosity is the term normally given to a coefficient which describes the diffusion of momentum. The formula for it is normally given as
v=n/rho where n is the dynamic viscosity and rho the density of the material under consideration.
The units for kinematic viscosity are the Stoke
The dynamic viscosity of a material is usually defined from the term
|shear stress|=n|strain rate|
For a newtonian fluid it is calculated from the following formula
Stress = n du/dy
The relationship between shear stress and strain rate is also known as the materials rheology
The units of dynamic viscosity are the poise
Hope this helps
