1)The Kinematic Viscosity is defined as the ratio of the dynamic viscosity to the densityof the fluid. Therefore the kinematic viscosity is inversely proportional to the density of the fluid.
2) Viscosity can be defined as resistance of fluid to flow. It is an important property of fluid and sign of internal friction. This resistance is caused from forces of attraction between fluid molecules. In simple term, viscosity is internal friction of fluid and also referred as thickness of fluid.
Viscosity is property of fluid that finds out amount of resistance of fluid to shear stress. Viscosity is property of fluid its offers resistance to movement of one layer of fluid above next layer. In simple words it is defined as property which offers resistance to flow.
