Hagen-Pouseuille's Law: Fluid Transport in a Tube | Fluid Mechanics

In this video, we will derive the Hagen-Poiseuille equation, named after the German engineer Gotthilf Heinrich Ludwig Hagen and the French physicist Jean Léonard Marie Poiseuille! This equation tells us that for a realistic fluid (including internal friction), the fluid transfer through a cylindrical tube scales with the fourth power of the radius. So if you double the radius of a pipe, 16 times as much fluid will flow through.

That was so well done! Thank you.

Thank you! :)

Things i noticed that got me confused first time
- A tilde (area of a fluid surface of equal velocity) is a *function of radius* , not a number
- The friction force on the fluid is proportional to dv/dx, change in velocity *along the radial direction from the center of the pipe* (because its shear?)
After this things start to make sense

sir why is there another equation 32vul/D^2
