Types of Viscosity

We can measure Viscosity by two methods and the viscosity measured by these two methods is called the types of viscosity. The two types of viscosity are:

  • Dynamic Viscosity (Absolute Viscosity)
  • Kinematic Viscosity

One way is to measure the fluid’s resistance to flow when an external force is applied. This is known as Dynamic Viscosity. And the other way is to measure the resistive flow of a fluid under the weight of gravity. We call this measure of fluid viscosity kinematic viscosity.

The Formula for Dynamic Viscosity is given as

Dynamic Viscosity = Shearing Stress/Shearing Rate Change

The Kinematic Viscosity Formula is given as

Kinematic Viscosity = Absolute Viscosity/Density of the Liquid

What is Viscosity?

Viscosity is the measurement of the resistance of the flowing liquid. Let us learn more about viscosity with an example suppose we take two bowls, one bowl contains water and the other has honey in it, we drop the content of both bowls then we see that water flows much faster than honey which concludes that honey is more viscous than water. 

Viscosity is the property of the liquids that prevents liquids from spreading. The force generated due to viscosity is called Viscous Force. Since this force is between the layers of liquids, it is also called internal friction. In this article, we will learn about viscosity its formula, measurement, and much more in detail.
