Prandtl boundary layer equations for two-dimensional steady laminar flow of incompressible fluid over a semi-infinite plate are given by uxu+vyu=1dxdp+vy22u,xu+yv=0, with boundary conditions i. Show that u=v=0wheny=0andu=Uwheny. 0u(uxuUdxdU)dy+0uvyu=v0uy22u. ii. Using (i) and boundary conditions, show that the kinetic-energy integral equation is given by dxd(U33)=2v0(yu)2dy
