Steel (AISI 1010) plates of thickness δ = 6 mm and length L = 1 m on a side are conveyed from a heat treatment process and are concurrently cooled by atmospheric air of velocity u[infinity] = 10 m/s and T[infinity] = 20°C in parallel flow over the plates. For an initial plate temperature of Ti = 300°C, what is the rate of heat transfer from the plate? What is the corresponding rate of change of the plate temperature? The velocity of the air is much larger than that of the plate.
