A thin, flat plate that is 0.2 m × 0.2 m on a side is orientedparallel to an atmospheric airstream having a velocity of 40 m/s.The air is at a temperature of ∞T∞= 20ºC, while the plate ismaintained at Ts= 120ºC. The air flows over the top and bottomsurfaces of the plate, and measurement of the drag force reveals avalue of 0.075 N. What is the rate of heat transfer from both sidesof the plate to the air?
