The space between two very long parallel plates separated by a distance

The space between two very long parallel plates separated by a distance of h is filled with a fluid. The fluid is heated in such a way that its viscosity decreases linearly from oat the lower surface to o/2 at the upper surface. The upper plate moves steadily at a velocity Uo relative to the lower one and the pressure everywhere is constant. Determine the velocity profile and the shear stress distribution. (Ans. In 1 ) 2h In 2 In 2 2h Uo V
