Mechanical Engineering > GATE 2017 SET-1 > Boundary Layer Theory
The velocity profile inside the boundary layer for flow over a flat plate is given as u/U = sin(πy / 2δ), where U is the free stream velocity and δ is the local boundary layer thickness. If δ* is the local displacement thickness, the value of δ*/δ is
A
2/π
B
1 - 2/π
C
1 + 2/π
D
0
