Viscosity Definition
Viscosity of any liquid is defined as,
“The measure of the resistance of the flow of the liquid.”
Viscosity is the property of any liquid which tells us how a liquid flow under the action of gravity. It tells that any liquid with a lower viscosity flows easily whereas the liquid with high viscosity flows with great difficulties.
Unit of Viscosity
SI unit for measuring the viscosity of liquid is Poiseiulle (PI). Other units used for measuring viscosity are Newton-Second per Square Metre (Nsm-2) or Pascal-Second (Pas)
Viscosity Dimensional Formula
Dimensional formula of the viscosity is [ML-1T-1]
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.
