The velocity profile in a laminar boundary layer is sometimes expressed in the formula u =ao+a₁ + a₂ +a3 U₁ where u₁ is the velocity outside the boundary layer and 8 is the boundary layer thickness. Evaluate the coefficients ao to a4 for the case when the pressure gradient along the surface is zero. +2 -a4 (b) Assuming a velocity profile u/u₁-2(y/8) - (y/8)² obtain an expression for the mass and momentum fluxes within the boundary layer and hence determine the displacement and momentum thickness.
