Air at free-stream velocity of 9 m/s flows over a thin flat plate of length 3 m and width 1.5 m. A laminar boundary layer develops from the leading edge of the flat plate. At Rex = 500 000, the boundary layer becomes a turbulent boundary layer where x is the distance from the leading edge. ρair = 1.2 kg/m3 , μair = 1.8 x 10-5 kg/m.s (a) Estimate the length of the laminar boundary layer.

In a lab experiment for a flat plate zero-pressure gradient boundary layer it is desired to find the friction coefficient (Cf) at location x=1 m from the leading edge of the plate. In order to do this, the momentum thickness of the boundary layer is measured at two locations 0.005m on either side of x=1m. the momentum thickness is measured to be 1.638 mm at x=0.995m and 1.652mm at x=1.005m, respectively, when the approach or free-stream velocity is 5m/s. a)...
