Fluid Mechanics II Viscosity and shear stresses

For fluids the shear stress τ is a function of the rate of strain dγ/dt The property of a fluid to resist the growth of shear deformation is called viscosity The form of the relation between shear stress and rate of strain depends on a fluid and most common fluids obey Newton s law of viscosity which states that the shear stress is proportional to the strain rate τ = µ dγ dt
