Assume a two-dimensional flow over a flat plate. Use the
result of Problem 1 for the thickness of the boundary layer and the velocity
profile for Vx, as given by Equation IVb.2.1 and obtain a relation
for Vy. [Hint: Use the equation for continuity given by Equation IIIa.3.13-1].
Start with Equation IVb.2.7 and obtain an approximate
relation for the thickness of the hydrodynamic boundary layer. Compare your
result with the exact solution.
