A$2.$ Consider a steady, two$-$dimensional, laminar, constant properties, fully developed flow

between two parallel plates separated by a distance $"$b$",$ flowing with an average velocity

$U_m.$ The two dimensions are x $($along the direction of the plate$)$ and its perpendicular

direction $y($along the direction between the plates$).$ If the pressure is independent of $y$ and

the body forces are neglected, obtain an expression for the velocity distribution.
