A steady and incompressible fluid flows over a flat surface. Fluid dynamic viscosity is = 1.01 x 10- Pas, and density p = 1000 kg/m (1) Find the boundary layer thickness at x=0.2 m from Blasius' exact solution. Free stream velocity U 1 m/s. (5') = (2) Find the boundary layer thickness & as a function of x for the laminar boundary layer if the velocity profile in laminar boundary layer can be assumed as = 2 7 = 2 /5 - (3) U S And S 0 when x = 0. (30') (3) Find the boundary layer thickness at x=0.2 m from the equation derived from (2). Free stream velocity U = 1 m/s. (5')
