A viscous, incompressible fluid is placed in the gap between to parallel plates of infinite length. If the lower plate is stationary, and the top plate moves with constant speed, U, determine the shear stress, and velocity distribution in the fluid between the two plates.1-25.In adopting a flux-gradient law, a simple relation is established between the movement of fluid particles and the gradient of an associated flow field. What is the fundamental hypothesis for a flux-gradient law to be at rue description of fluid motion? Is it possible to express the volume lux in a viscous fluid in terms of the gradient of some scalar field?
