Reynolds and Womersley Dimensionless Numbers. a). Define the Reynolds number Re. At what value of the Reynolds number would you expect flow in a tube to transition from laminar to turbulent? b). Define the Womersley number Wo. For unsteady laminar flow in a circular tube, at what value of the Womersley number would you expect flow to deviate from Hagen-Poiseuille flow? c). Search the web to estimate typical values of Re and Wo to complete the table below
