1. BackgroundBorn in Paris, Francecole Polytechnique: Disband
for political reasonsMedicine: Interest in circulation of blood led
to series of experiments on the flow of liquid in narrow tubesD.Sc.
Dissertation: Heart and pulse wavesPoiseuilles Law: Commonly known
as Hagen-Poiseuille equationPoise: Unit of viscosity
2. ContributionsPoiseuilles law Governs flow in a tube as a
function of diameterInvention of Mercury ManometerUsed for
measuring blood flow hence mmHgExperiments contributed to various
fieldsEngineeringPhysicsMedicine Biology
3.1 Derivation123
3.2 ApplicationsPoiseuilless Law hold for most systems involving
laminar flow of a fluid in a rigid pipe, except at regions where
pipe features disrupts laminar flow.
It can be successfully applied to:Air flow in lung alveoliBlood
flowFlow through a drinking strawFlow through a hypodermic needle
etc.
3.2 LimitationsLaw is restricted to:Incompressible and Newtonian
fluidFlow must be laminar through a pipe of constant
cross-sectional area, with length substantially longer than its
diameterThere should be no acceleration of the fluid in the
pipe

law for electrical circuits
