A heated 6-mm-thick Pyroceram plate (rho = 2600 kg/m3, cp = 808 J/kg·K, k = 3.98 W/m·K, and α = 1.89 × 10–6 m2/s) is being cooled in a room with air temperature of 25°C and convection heat transfer coefficient of 13.3 W/m2·K. The heated Pyroceram plate had an initial temperature of 503°C, and is allowed to cool for 286 seconds. The mass of the Pyroceram plate is 7 kg. Determine the heat transfer from the Pyroceram plate during the cooling process. (Given: λ1 = 0.0998, A1 = 1.0017)
