h4. Problem

Use FLUENT to resolve the developing flow in a pipe (same configuration         as was done in the tutorial) for a pipe Reynolds number of 10,000 on         the following meshes: 100x5, 100x20 with uniform spacing in the radial         direction.         Plot         the skin friction _c{_}{_}{~}f{~}_ as a function of axial location         for each grid. Compare the exit value with the expected value for fully         developed flow (e.g., see White pgs. 345-346). Recall that a key question         for the integrity of the mesh is the non-dimensional value of the first         nodal point:
