Question
A pizza oven has an interior temperature of 250◦C and the outside ambient kitchen temperature is 25◦C. The oven is made of brick 20 cm thick of thermal conductivity kb = 1 W/m/K. It is covered with an insulating material 1 cm thick of conductivity ki = 0.05 W/m/K. The heat transfer coefficient at the insulation surface is h = 15 W/m2/K, while the heat transfer coefficient at the inner surface of the oven has a very large value. Assume a planar (slab) geometry. Determine
(a The heat flux from the oven
(b If the heat flux is to be reduced to 400 W/m2, what additional thickness of insulation will be required?
