Question #64765
The inside of a baking oven is at a temperature of 177degrees celcius. The wall of an oven is made up of 4mm thick stainless steel of thermal conductivity 15.5W/mk. Determine the heat conduction heat loss per unit area from the oven if outside temperature is at 27degrees celcius above room temperature
Expert's answer
The heat conduction heat loss per unit area from the oven is
Q=kA ΔT/Δx
Q/A=k ΔT/Δx=15.5 (177-27)/0.004=581250 W/m^2 .
Answer: 581250 W/m^2 .
