3.10-4. Transition Point to Turbulent Boundary Layer. Air at 101.3 kPa and 293 K is flowing past a smooth flat plate at 100 ft/s. The turbulence in the air stream is such that the transition from a laminar to a turbulent boundary layer occurs at 5 × 105. NRe, L = (a) Calculate the distance from the leading edge where the transition occurs. (b) Calculate the boundary-layer thickness & at a distance of 0.5 ft and 3.0 ft from the leading edge. Also calculate the drag coefficient for both distances L = 0.5 and 3.0 ft.
