Consider steady, parallel flow of atmospheric air over a flat plate. the air has a temperature and free stream velocity of 300 k and 25 m/s. (a) evaluate the boundary layer thickness at distances of x 1, 10, and 100 mm from the leading edge. if a second plate were installed parallel to and at a distance of 3 mm from the first plate, what is the distance from the leading edge at which boundary layer merger would occur? (b) evaluate the surface shear stress and the y-velocity mponent at the outer edge of the boundary layer for the single plate at x 1, 10, and 100 mm. (c) comment on the validity of the boundary layer approximations.
