Newton’s law of Viscosity
Newton’s law of viscosity states that the shear stress on a fluid element layer is directly proportional to the rate of shear strain. The constant of proportionality used in Newton's equation is known as coefficient of viscosity.
What is a Newtonian Fluid?
Fluids that obey Newton’s law of viscosity are known as Newtonian fluids. In a Newtonian fluid, there is a linear relation between the magnitude of shear stress and the resulting rate of deformation.
Most of the common fluids follow Newton’s equation of viscosity. There are certain fluids which, however, do not follow Newton’s law of viscosity. Accordingly, fluids are classified as Newtonian fluids and non-Newtonian fluids.
Examples of Newtonian fluids
* Air
* Water
* Glycerine
* Kerosene
Examples of Non-Newtonian fluids
* Solutions or suspensions (slurries)
* Mud flows
* Polymer solutions
* Blood
