Air at 70°f flows parallel to a smooth, thin, flat plate at 16.5 ft/s. the plate is 10.6 ft long. determine whether the boundary layer on the plate is most likely laminar, turbulent, or somewhere in between (transitional). calculate the boundary layer thickness at the end of the plate where the boundary layer is laminar everywhere and where the boundary layer is turbulent everywhere (obtained from the one-seventh-power law). the kinematic viscosity of air at 70ºf is ν
