4ookla Pa Pump D = 3cm D = 9cm Consider a steady-laminar-incompressible flow between two plates where the one at the top is fixed and the one at the bottom is moving at a speed of (U) at the "x" spatial direction while the velocity profile of the flow between the plates are u(y). If the distance between the plates at the "y" direction is b, derive an expression of the fluid velocity using Continuity and Navier-Stokes equations (Draw a schematics). (30 p)
