Continuity Equation

Momentum Equation

Under what conditions?????

So, From continuity equation

where

Simplest type of Couette flow

Steady, Laminar Flow in Circular Tubes Probably the best known exact solution to the Navier–Stokes equations is for steady, incompressible, laminar flow through a straight circular tube of constant cross section. This type of flow is commonly called Hagen-Poiseuille flow, or simply Poiseuille flow.

Continuity equation
