The Reynolds number, Re is defined as UαL/ν where L is the length scale for a flow, Uα is its reference velocity and ν is the coefficient of kinematic viscosity. In the laminar boundary layer approximation, comparison of the dimensions of the convection term and the viscous term u ∂u/∂x ν∂2u/∂x2 leads to the following relation between the boundary layer thickness δ and Re:
Correct : b
