1. Calculate the local skin friction and the local drag coefficient for a plate of length L, using the previous sinusoidal velocity profile.
2. Assuming a velocity profile for the laminar flat plate in the form

develop a relation for the boundary layer (δ/x) as a function of the local Reynolds number by evaluating the von Karm´ an integral equation. Compare with the exact ´ results of Blasius.
