1. A streamline in 20-C water is 2 mm from a flat plate at the leading edge. Using the parabolic velocity profile of Sec. 8.5.3 with U1 ¼ 1 m=s, predict how far from the plate the streamline is when x ¼ 1 m.
2. Show that the power-law form for the velocity profile in a turbulent fiow is not a good approximation at the wall or at the outer edge of the boundary layer.
