DFCCIL_CE _Quiz 10

Find the energy thickness for velocity distribution in the boundary layer given by u/U = y²/δ², where u is the velocity at a distance y from the plate and u = U at y = δ where δ = boundary layer thickness.

The slope of HGL will be

For laminar flow through a pipe, the discharge varies?
