Mechanical Engineering > GATE 2017 SET-2 > Boundary Layer Theory
Consider a laminar flow at zero incidence over a flat plate. The shear stress at the wall is denoted by τw. The axial positions x1 and x2 on the plate are measured from the leading edge in the direction of flow. If x2 > x1, then
A
τw|x1 = τw|x2 = 0
B
τw|x1 = τw|x2 ≠ 0
C
τw|x1 > τw|x2
D
τw|x1 < τw|x2

Correct : c
