Consider concentric annulus with inner radius i r and outer radius o r . There is no axial flow. The outer surface is fixed and the inner surface rotates with constant angular velocity. The annulus space is occupied by a Non-Newtonian fluid [ ( )n dV dr     ]. Develop an equation for friction coefficient, mean velocity
