Viscosity § Shear stress (τ): force required to slide one
unit area layer of a substance over another § Viscosity (µ): measure of a fluid’s resistance
to flow when acted upon by an external force (i.e., ease with which a fluid pours)
§ As a fluid moves a shear stress is developed in it; magnitude is dependent on viscosity of fluid
