Consider incompressible, steady, fully-developed laminar flow between infinite parallel, horizontal plates. The upper plate moves to the right at 3mm/s. There is no pressure variation in the x direction, but there is a constant body force, pB = 800 N/m^3. The clearance gap between the plates is h=0.1 mm and the liquid viscosity is 0.02 Pa.s.
Evaluate the velocity profile if y=0 at the stationary lower plate. Draw the velocity and shear stress profiles. Compute the volume flow rate past a vertical section
