After heat treatment, the 2-cm thick metal plates (k = 180
W/m·K, ρ = 2800 kg/m3, and cp = 880 J/kg·K) are conveyed through a
cooling chamber with a length of 10 m. The plates enter the cooling
chamber at an initial temperature of 500°C. The cooling chamber
maintains a temperature of 10°C, and the convection heat transfer
coefficient is given as a function of the air velocity blowing over
the plates h = 33V0.8, where...
