The flat plate, 1 m in length and 1 m in width, is placed parallel to the air stream at 27ºC, 1 atm. The air free stream velocity is 3 m/s and only one side of the plate is exposed to the air stream. Radiation from sun is absorbed at the plate surface at the constant rate of 300 W/m2. What will be the average surface temperature of the plate?
