Fully developing flow
As a fluid enters a pipe and progresses further down, does the shear stress at the wall reduce whilst the boundary layer increases and viscous forces take over?
Yes. The shear stress is proportional to the gradient of velocity (in the direction normal to the wall) and since the gradient is larger in the developing region, the shear stress will also be larger here as well.
