Question

Define coefficient of viscosity and write it's si unit

Answer 1

The degree to which a fluid resists flow under an applied force, expressed as the ratio of the shearing stress to the velocity gradient. The coefficient of viscosity of liquids decreases as temperature increases because the bonds between molecules are weakened.

The SI units generally used are pa.s (Pascal second) or (N.s)/m^3

Hope this helps u!

Answer 2

The property of fluids to resists their motion under the applied force is viscosity. Example honey is more visvous than water.
the coefficient of viscosity of a liquids generally decreases with rise in temperature whereas for vases it increases with tenperature.
SI unit is poiseiulle and other unit is N s m^-2
