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. (b) Estimate the drag force due to the laminar boundary layer on one side of the flat plate. (c) Estimate the boundary layer thickness and wall shear stress at x = 2.5 m. (

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)...
