A) a long, thin flat plate is placed parallel to a 6 m/s stream of water at 20°c. at what distancexfrom the leading edge will the boundary layer thickness be 3 cm?
(b) are low-speed, small-scaleair and water boundary layers really thin? consider flow with u= 1 ft/s past a flat plate 1 ft long. compute the boundary layer thickness at the trailing edge for (i) air and (ii) water at 68°f.
