A 1-in. thick, 10 ft long flat plate has its outside surface maintained at 240℉. Air at 60℉ and atmospheric pressure is forced past this plate with a velocity of 40 fps. Determine the heat flux from the plate to the air if the flow of air is parallel to the plate. [Hint: Use the laminar scenario for flows in transition.]
