Refractory bricks are used as linings for furnaces, and they generally have low thermal conductivity to minimize heat loss through the furnace walls. Consider a thick furnace wall lining with refractory bricks (k = 1.0 W/m·K and a = 5.08 * 10-7 m2/s), where initially the wall has a uniform temperature of 15°C. If the wall surface is subjected to uniform heat flux of 20 kW/m2, determine the temperature at the depth of 10 cm from the surface after an hour of heating time.

Question
Refractory bricks are used as linings for furnaces, and
they generally have low thermal conductivity to minimize
heat loss through the furnace walls. Consider a thick furnace
wall lining with refractory bricks (k = 1.0 W/m·K and a =
5.08 * 10-7 m2/s), where initially the wall has a uniform temperature
of 15°C. If the wall surface is subjected to uniform
heat flux of 20 kW/m2, determine the temperature at the depth
of 10 cm from the surface after an hour of heating time.
