Viscosity
1. What is Viscosity?
Viscosity is the measure of a fluid’s resistance to the flow of liquid.
2. What is Unit for Coefficient of Viscosity?
SI unit of the coefficient of viscosity is N s m-2.
3. What is Viscosity of Water?
Viscosity of water at 20 degrees Celsius is roughly equal to 0.01 poise or 10-3 Pa. s (Pascal seconds)
4. How is Viscosity Measured?
Viscosity of a liquid is measured using the Viscometer.
5. How does Viscosity Vary with Temperature?
Viscosity of liquids decreases with the increase in temperature, and viscosity of gases increases with the increase in temperature.
6. What is Newton’s Law of Viscosity?
Newton’s Law of Viscosity states that the shear stress applied between the two layers of fluid is directly proportional to the velocity gradient between the two layers.
7. What is Viscosity Index?
Viscocity Index is an Imperical measure of the viscosity of lubricating oil whose change in temperature is Viscocity Index.
8. What is Viscosity of Blood?
The normal viscosity of blood is, between 3.5 and 5.5 cP
9. What is Viscocity for Air?
The viscosity of air at 15°C is 1.81 × 10-5 kg/(m·s) OR 18.1 μPa·s.
10. What is Honey Viscosity?
Honey is a highly viscous material and it has a viscosity of 10000 cps.
11. What is Viscocity of Water?
Viscocity of water at 20°C is 0.01 poise OR 10-3 Pa.s
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.
