Which statement is correct about velocity boundary layer in external flow (select all that apply): O it has a larger thickness for fluids with larger kinematic viscosity It is a region at which the velocity in the y-direction is affected by the presence of the surface It is a region at which the velocity in the x-direction is affected by the presence of the surface It has a larger thickness for flows with higher velocity It is growing with increase of x until it reaches to a constant thickness
