Quick comparison between Dynamic viscosity and Kinematic viscosity

Dynamic viscosity
Kinematic viscosity
Also called Absolute viscosity.
Also called Diffusivity of momentum.
Quantitative expression of resistance to fluid flow.
It is the ratio of shear stress to the shear strain (or velocity gradient).
It is the ratio of dynamic viscosity to density.
It represents the viscous force of the fluid.
It represents both viscous force and inertia force in fluids.
Useful where viscous forces are dominant.
Use full were both viscous force and inertia force are dominant.
