Consider a laminar boundary layer on a flat plate with uniform suction velocity Vo as shown in fig. $4.$ Far down the plate $($large x$),$ a fully developed situation may be shown to exist. In this region, starting from general 'boundary layer equations' deduce an expression for $(3)$ velocity distribution and $(6)$ wall shear stress. One of the boundary conditions $($in addition to other conditions as seen from the Fig $4.)$ you can use is: At y$=\backslash$infty ;u$=$U$.$
