Consider a steady two dimensional zero-pressure gradient laminar flow of air over a flat plate as
shown below. The free stream conditions are U∞=100 ms-1 ρx=1.2 kgm-3, pα=1 atm and
μ∞=1.8×10-5 kgm-1s-1. The ratio of displacement thickness to momentum thickness of the
boundary layer at a distance of 2 m from the leading edge is
A
7.53
B
2.59
C
2.91
D
0.39

Correct : b
