Reynold's Number - Video Lesson

Hey, everybody. Welcome to today's lesson on hemodynamics. This lesson focuses on Reynolds number, which is a value used to predict the type of flow pattern occurring within a vessel. Reynolds number helps us to analyze and predict fluid behaviors in various clinical contexts, leading to identifying circulatory disorders early, which improves patient outcomes. Reynolds number is a dimensionless value, meaning it does not have a unit of measure like centimeters or millimeters. It determines whether blood flow is laminar or turbulent. In other words, the Reynolds number tells us if blood flow is smooth and orderly or if it is chaotic and disturbed. Higher Reynolds numbers generally indicate turbulent flow, while lower Reynolds numbers indicate laminar flow. The equation for Reynolds number is r e is equal to rho times v times d all over eta, where rho equals density of the fluid, blood, v,
