Air flows over a flat plate (L = 10m) with zero incidence and constant pressure gradient over the surface.
Kinematic viscosity of air is 15 centistokes and mass density is 1.2 kg/m3. If Blassius constant is 5 and the velocity profile is linear in laminar boundary layer, what is the free stream velocity of air, in m/sec?
Boundary layer thickness is limited to 7.33mm.1
