Note: This is an "advanced" question. Likely more difficult than would appear on an exam. I've included it here as another example of solving the Navier-Stokes equations.
Chapter 4 Solved Problem: Navier-Stokes Equations (15:14)
An exact solution of the continuity and Navier-Stokes equations is presented in cylindrical coordinates. This is the classical solution for constant-property laminar flow in a concentric annulus. A viscous incompressible fluid flows between a moving inner solid rod and a stationary outer tube. An expression is derived for the axial velocity distribution.
