Consider a flat plate, with a sharp leading edge, placed in a uniform flow of speed U. The direction of the free-stream flow is aligned with the plate. Assume that the flow is steady, incompressible and laminar. The thickness of the boundary layer at a fixed stream-wise location L from the leading edge of the plate is δ. Which one of the following correctly describes the variation of δ with U?
A
δ ∝ U
B
δ ∝ U3/2
C
δ ∝ U1/2
D
δ ∝ U-1/2

Correct : c
