1.4 The space between two very long parallel plates separated by a distance of h is filled with a fluid.

1.4 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 Limearly from at the lower surface to p/2 at the upper surface. The upper plate moves steadily at a velocity Uo relative to the lower one and the pressune everywhere is constant. Determine the velocity profile and the shear strese distribution
