Question

what is coefficient of viscosity?

Answer 1

hey dude here's ur answer,,,,,➡➡➡

Coeffecient of VISCOSITY is the ratio of SHEARING STRESS to the VELOCITY GRADIENT....




(or). IT is a measure of the degree to which fluid is resisted..

❤❤hope it helps u

Answer 2

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.

The result is that liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

The coefficient of viscosity is a measure of resistance to flow of the fluid. Dynamic viscosity μ is used in Darcy's law to calculate the rate of fluid flow in porous media. The relationship between viscosity and flow rate defines the rheology of the fluid.
