Question

A stream of air at 1 atm and 90 \deg F flows at a velocity of 140 ft/s along a 3 ft long flat plate. The surface of the plate is maintained at 450 \deg F. For a plate 1 ft wide calculate: a. The heat loss in the section of the plate where there is laminar flow. b. The heat loss in the section of the plate where there is turbulent flow. c. The total heat loss in the entire plate. Assume that laminar flow occurs at Rez<300,000 and turbulent flow occurs at Re>300,000.
