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 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.
