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. Find typical values for the aorta, major arteries, terminal artery, etc. from the literature. Sketch the anticipated velocity profile and indicate which forces are expected to be dominant in each of these systems.
