Consider a large aluminum plate of 10.0cm thickness. It was originally at 200C and then suddenly dipped into an oil bath. The oil bath is maintained at 70C it produces convective cooling of the plate with heat transfer coefficient of 8600W/m2 C. Calqulate the temperature at the depth of 2.0cm from the plate's surface when the heat loss from the plate is 23.7MJ per unit area. Physical properties available for aluminum: Density =2700kg/m3 Heat capacity =0.9kJ/kg.K Thermal conductivity =215W/m.K
