Consider two concentric cylinders of infinite length and incompressible flow of a liquid with constant viscosity through the annulus formed by the cylinders. The flow is maintained by an axial pressure gradient. Neglecting body force and assuming fully-developed condition, develop the expressions for steady-state velocity profile through the annulus, shear stress at both the surfaces and stream function. Also find the radial location of the maximum flow velocity.
