How liquids flow: laminar, transitional and turbulent flow (simple tutorial)

This tutorial explains three different types of flow:
- laminar flow (ordered),
- transitional flow, and
- turbulent flow (disordered).

It also briefly covers some of the factors that influences how a liquid will flow, including liquid velocity, viscosity, and density, and pipe diameter - and how these are combined in Reynolds number. If Reynolds number is less than 2000, the liquid is likely to be flowing in laminar flow; over 4000 it is likely flowing in turbulent flow.
