Poiseuille's Law

Noun

/pwɑːˈzɛɪ/

Definition

Poiseuille’s Law describes the flow of a fluid through a cylindrical pipe, emphasizing the dependence of flow rate on the radius, viscosity, and length of the pipe.

Examples

According to Poiseuille’s Law, increasing the radius of a pipe will significantly enhance the flow rate.
In a laboratory experiment, we applied Poiseuille’s Law to analyze fluid dynamics in narrow tubes.

Meaning

It quantifies how the flow rate of an incompressible and laminar fluid is affected by various factors, mainly the radius of the pipe and the difference in pressure.
