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
Correct : b
