a) A successful Fluid Dynamics lecturer uses a board above their automobile to promote their course as shown in Figure Q1 below. They drive at a speed of 10 metres per second, and the board is 3 metres long and 1.5 metres high. Determine the boundary layer thickness on the surface of the board. b) In the given scenario, calculate the shear force on the board's laminar boundary layer section. c) Determine the shear force on the board's turbulent boundary layer section in the case above. Briefly explain the comparison of the result with Q1 b). Given: (p = 1.225kg/m³,µ = 1.5x10-5kgm¯¹s-¹)
