Viscosity is resistance to shear or flow in a fluid – and a measure of the adhesive/cohesive or frictional property. Viscosity arising due to internal molecular friction produces the frictional drag effect. There are two related measures of fluid viscosity – known as dynamic (or absolute) and kinematic viscosity.
