Viscosity is a liquid's resistance to flow. [1]
- It describes the internal friction of a moving fluid. Friction acts tangentially opposite to the direction of relative motion between adjacent layers of the fluid. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. Viscosity is governed by Stoke's Law.[2]
