An incompressible, viscous fluid is shownbetween horizontal, infinite parallel plates. The plates move in opposite directions with constant velocities U1and U2. The flow is laminar. The pressure gradient in the x-direction is zero, and the only body force is due to the fluid weight. Under steady-flow condition:(a)Solve the system of mass conservation equation and x-component of Navier-Stokes equationsto obtain a differential equation forthe velocity component, u.(b)State the proper boundary conditions, and solve for the velocity distribution, u(y).(c)Derivean expression for the volume flow rate, Q, based on the unit width of the flow(width
