List of top Fluid Mechanics and Mechanical Operations Questions on Flow through pipeline systems

Consider the steady, uni-directional, fully-developed, pressure-driven laminar flow of an incompressible Newtonian fluid through a circular pipe of inner radius 5.0 cm. The magnitude of shear stress at the inner wall of the pipe is 0.1 N m\(^{-2}\). At a radial distance of 1.0 cm from the pipe axis, the magnitude of the shear stress, in N m\(^{-2}\), rounded off to 3 decimal places, is ____.
