Question

define cofficient of viscosity

Answer 1

Coefficient of viscosity for a fluid is defined as the ratio of shearing stress to the strain rate.

Answer 2

$\huge \bf{ \underline{ \underline \red{Answer - }}}$

____________________________________________

$\implies$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.
