Steel plates (AISI 1010) with a thickness of 6 mm and sides with a length L = 0.49 m, are transported at the exit of a heat treatment process and simultaneously cooled by atmospheric air with a speed u∞ = 5.24 m/s and T ∞ = 23.3°C in parallel flow over the plates. For an initial plate temperature of Ti = 327°C, what is the heat transfer rate in W leaving the plate? Considering that the air velocity is much greater than the plate velocity, what is the corresponding temperature change rate for that instant in K/s
