Question $5$: Consider a steady, incompressible $($ $=$ constant$),$ laminar boundary layer flow over a surface with free$-$stream velocity U$($x$),$ which may vary with the distance from the leading edge, x$.$ Assuming negligible body forces and constant fluid viscosity: $($a$)$ Show that the pressure in the boundary layer will be: $()=0+2(02()2)$ where P$0$ and U$0$ are the velocity and pressure at x$=0.$ List the assumptions you made in showing the result.
