Jean Léonard Marie Poiseuille

Jean Léonard Marie Poiseuille was a French physicist and physiologist known for discovering how fluids, like blood or water, flow through narrow tubes. He studied the relationship between the flow rate, the tube’s size, the fluid’s viscosity, and pressure, leading to what’s now called Poiseuille’s Law. This principle helps understand and predict how fluids move in medical devices, pipes, and natural systems. His work was fundamental in understanding cardiovascular health, engineering fluid systems, and improving technologies involving the flow of liquids.
