The Physics Behind Flow — Bernoulli, Continuity, and Pressure Drop

The Physics Behind Flow — Bernoulli, Continuity, and Pressure Drop
How Classic Laws of Fluid Dynamics Explain What You See

Why does pressure drop inside your vascular model? And why does fluid slow down in wider vessels even though the pump output stays the same? This article explores how Bernoulli’s principle, the continuity equation, and Poiseuille’s law explain what you observe in pulse duplicating systems — complete with a real-world case study and step-by-step calculation. A must-read for anyone using pumps in medical simulation.
