Fully-developed steady laminar flow is driven between two parallel plates by a pressure gradient in the x-direction. The upper plate at y=H/2 is stationary and the lower plate at y=-H/2 moves to the right with velocity Uwall.  Assume that v=0 and w=0 everywhere in the flow field and that the flow is fully-developed and steady.  Neglect body forces. To solve this problem, you will use the x-momentum equation.  For the flow described above, mark ALL boundary conditions that are used to find the x-direction velocity profile.
