Problem 11: Laminar flow between horizontal parallel plates Derive the equation giving the velocity distribution at steady state for laminar flow of a constant density fluid with constant viscosity flow between two flat and parallel plates. The velocity profile desired is at a point far from the inlet or outlet of the channel. The two plates will be considered to be fixed and of infinite width, with the flow driven by the pressure gradient in the x-direction. top plate bottom plate flow in x direction.
