Jean Léonard Marie Poiseuille[a] (French: [pwazœj]; 22 April 1797[1] – 26 December 1869) was a French physicist and physiologist. Poiseuille was born in Paris, France, and he died there on 26 December 1869. Contents 1 Fluid flow 2 Notes 3 References 4 Further reading Fluid flow[edit]
From 1815 to 1816 he studied at the
Δ P = 8 μ L Q π r 4 , displaystyle Delta P= frac 8mu LQ pi r^ 4 , or Δ P = 128 μ L Q π d 4 , displaystyle Delta P= frac 128mu LQ pi d^ 4 , or Δ P = 32 μ L v d 2 , displaystyle Delta P= frac 32mu Lv d^ 2 , where: Δ P displaystyle Delta P is the pressure loss, L displaystyle L is the length of pipe, μ displaystyle mu is the dynamic viscosity, Q displaystyle Q is the volumetric flow rate, r displaystyle r is the radius, d displaystyle d is the diameter, π displaystyle pi is the mathematical constant π, v displaystyle v is the velocity. The poise, the unit of viscosity in the CGS system, was named after him. Attempts to introduce "poiseuille" as the name of the SI unit Pa·s had little success.[citation needed] Notes[edit] ^ Some sources (including editions of
