The correct relationship among displacement thickness ‘d’ momentum thickness ‘m’ and energy thickness ‘e’ is
What is the momentum thickness for the boundary layer with velocity distribution u/U = y/δ ?
If x is the distance from leading edge, then the boundary layer thickness in laminar flow varies as
If δ_{1} and δ_{2} denote the boundary layer thicknesses at a point distance x from the leading edge on a fiat plate when the Reynolds numbers are 100 and 256 respectively, then the ratio of δ_{1} to δ_{2} will be
If δ_{1} is the thickness of laminar boundary layer at a distance x_{1} from the leading edge of the flat plate, the thickness δ_{2} at x_{2} = 2x_{1} is equal to
