Question: The space between two concentric spheres is filled with an incompressible fluid at a fixed temperature. The radii of the inner and outer wetted surfaces

The space between two concentric spheres is filled with an incompressible fluid at a fixed temperature. The radii of the inner and outer wetted surfaces are kR and R, respectively. The angular velocity of the inner sphere is Q, and the outer sphere is stationary. Use the Navier-Stokes equation to determine the velocity distribution in the fluid.
