Fluid Mechanics

19.

In case of turbulent flow of fluid through a circular pipe, the

mean flow velocity is about 0.5 times the maximum velocity.

velocity profile becomes flatter and flatter with increasing Reynolds number.

point of maximum instability exists at a distance of 2r/3 from the pipe wall (r = pipe radius).

skin friction drag, shear stresses, random orientation of fluid particles and slope of velocity profile at the wall are more.
