Air at standard pressure flows across a flat plate at 3m/s. the temperature surface is 50â°c and the surrounding temperature is 20â°c. consider a point 1m away from the leading edge of the plate. see table a-15 in appendix 1 for properties of air. a. determine the reynold's number and prandtl number for this flow. b. determine the flow boundary layer thickness. c. determine the thermal boundary layer thickness for this flow. d. find the local nusselt number. e. based on this nusselt number, what is the local convective heat flux from the plate to the air?
