... The shear stress is proportional to the rate of change of velocity, also called du the velocity gradient. We can write this as: τ ∝ dy So near the surface, the shear stress is high, while on moving further into the stream the shear stress gets smaller. ...

Fluid Friction in Pipes
... In Chemical engineering process operations , fluids are typically conveyed through pipelines, in which viscous action. Such friction is normally overcome either by means of the pressure generated by a pump or by the fluid falling under gravity from a higher to a lower elevation. In both cases it ...
