Chapter 6, Problem 6.49(choose chapter or problem)
A thin, flat plate that is 0.2 m?0.2 m on a side withrough top and bottom surfaces is placed in a wind tun-nel so that its surfaces are parallel to an atmosphericairstream having a velocity of 30 m/s. The air is at atemperature of T??20C while the plate is maintainedat Ts?80C. The plate is rotated 45about its centerpoint, as shown in the schematic. Airflows over the topand bottom surfaces of the plate, and measurement ofthe heat transfer rate is 2000 W. What is the drag forceon the plate?
