The flow profiles was first derived by John R. Womersley (1907–1958) in his work with blood flow in arteries. [1] The cardiovascular system of chordate animals is a very good example where pulsatile flow is found, but pulsatile flow is also observed in engines and hydraulic systems, as a result of rotating mechanisms pumping the fluid.
In a flow distribution network that progresses from a large tube to many small tubes (e.g. a blood vessel network), the frequency, density, and dynamic viscosity are (usually) the same throughout the network, but the tube radii change. Therefore, the Womersley number is large in large vessels and small in small vessels.

Both Mekong and the distributary Bassac then flow towards the Cambodia–Vietnam border. After entering Vietnam, Mekong is known as the Tiền River (or Fleuve Antérieur in French, meaning "prior river") while Bassac is known as the Hậu River (Vietnamese: Sông Hậu/ Hậu Giang or French: Fleuve Postérieur, meaning "posterior river").
