2. Calculate the shear stress τxy at the wall in the fully-developed region for the three meshes. Calculate the corresponding value from fully-developed pipe analysis in HW6. For each mesh, calculate the % error relative to the analytical value. Include your
results as a table:

3. At the exit of the pipe where the flow is fully-developed, we can define the error in the centerline velocity as
