Problem 5 (CCO#6) (20 points) Consider a boundary layer flow of air over a flat plate. The upstream velocity is U., = 10m / s . For air, take p - 1.23kg /m , u - 1.8x10 Pa. s. (a) At a location "A", not too far from the leading edge of the flat plate, the boundary layer flow is laminar (thus, one can assume that the Blasius solution applies at "A"), and the wall shear stress at "A" is measured to be 7., - 0.494Pa . What is the distance of this location "A" from the leading edge (which is at x = 0)? (6 points) (b) What is the local Reynolds number Re _PU.x at "A"? Is the flow indeed laminar at "A"? (6 LI points) (c) Let the plate length and width to be _ = 2m, b = 1m , respectively. Find the drag on the plate (one side only) using the most accurate friction drag coefficient formula for a flat plate.
