The figure below shows two parallel, horizontal infinite plates. Between the plates is a

fluid between the plates. The velocities and directions of movement of the plates are shown in the

figure. The pressure gradient in the x direction is zero. The force of gravity is the only field force

acting on the system. Use the Navier$-$Stokes equations to obtain the velocity profile in the

flow between the plates. Consider the flow between the plates to be laminar.
