railway RRB JE (CBT I + CBT II) Mock Test 2024 Fluid Mechanics Properties of Fluids Newton Law of Viscosity
Newton's law of viscosity states that,
1
the shear stress between adjacent fluid layers is inversely proportional to the velocity gradients between the two layers.
2
the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers.
3
the shear stress between adjacent fluid layers is inversely proportional to the dynamic viscosity of fluid between the two layers.
4
None of the above
