1. (15 points] A boundary layer formed on one side of a plate of length L produces a friction drag force D. Using the expressions for tw given for laminar and turbulent boundary layers, how much must the plate be shortened if the drag on the new plate is to be D/4? (a) When the boundary layer is laminar (b) When the boundary layer is turbulent from the beginning? Assume everything else remains the same.
