Question
Outer pipe wall
Consider the steady, incompressible, laminar flow of a Newtonian fluid in
an infinitely long round pipe annulus of inner radius R, and outer radius
Ro. Assume that the pressure is constant everywhere there is no forced
pressure gradient driving the flow, Pi = P2. However, let the inner
cylinder be moving at steady velocity V to the right, essentially a piston.
The outer cylinder is stationary. This makes an axisymmetric Couette
flow. Use cylindrical coordinates and the equations of motion to generate
an expression for the x-component of velocity u as a function of r. Ignore
the effects of gravity.
