The shear stress distribution for a fluid flowing in between the parallel plates, both at rest, is                        

If x is the distance from leading edge, then the boundary layer thickness in laminar flow varies as                        

Stanton diagram is a                        

The depth 'd' below the free surface at which the point velocity is equal to the average velocity of flow for a uniform laminar flow with a free surface, will be
where D is the depth of flow.                        

The boundary layer thickness in turbulent flow varies as
where x is the distance from leading edge.                        

The distance y from pipe boundary, at which the point velocity is equal to average velocity for turbulent flow, is
where R is radius of pipe.
