Want this question answered?
It is the ratio of the dynamic viscosity to the density of the fluid.
dynamic viscosity is the quantitative expression of fluid's resistance,while kinematic viscosity is the ratio of fluid viscous force to inertial force.
You have to distinguish dynamic viscosity and kinematic viscosity. Different units are used for both - the standard (SI) unit for dynamic viscosity is Pascal x second, while the unit for kinematic viscosity is meter2/second.

The kinematic viscosity of a fluid is found by dividing the dynamic viscosity by the density of the fluid. The kinematic viscosity of water changes depending on the temperature of the water. It ranges from .29 SI units to 1.787 SI units.
Kinematic viscosity is the ratio of dynamic viscosity to density of the fluid. The SI unit of the quantity is square meter per second (symbol m²/s). The most frequent used unit of kinematic viscosity is Centistokes (cSt). 1 Centistokes (cSt) is the kinematic viscosity of a fluid with dynamic viscosity of 1 cP and volumic mass 1 g/cm³.
Fluid behavior is related to both density and viscosity. By using the kinematic and dynamic viscosity of a fluid, the density can be calculated.
The Si unit for viscosity is Pa·s = kg/(s·m).
Water at 30 degrees has a dynamic viscosity (µ) of 0.798 (kg/m.s) or a kinematic viscosity of (v) 0.801.Need more help? Go check out http://www.engineeringtoolbox.com/water-dynamic-kinematic-viscosity-d_596.html
what is the significance of kinamatics viscosity
At 22oC: kinematic viscosity is: 1.0004 (m2/s)x10-6 dynamic viscosity is: 1.002 (Ns/m2)x10-3
