Consider the flow of warm water (t =350 k) over a cool, flat surface. a) how will the thicknesses of the velocity and thermal boundary layers compare if the flow is laminar? (that is, which is larger, the velocity or thermal boundary layer? ) why? the flow is turbulent? why? why? b) how will the thicknesses of the velocity and thermal boundary layers compare if c) which flow would likely lead to a larger rate of heat transfer: laminar or turbulent?
