A kiln used to make ceramics has a wall composed of firebrick. The heat conduction coefficient for firebrick is 1.04 W/m·K, the exterior wall temperature is 100°C, the room temperature is 25°C, the emissivity of firebrick is 0.8, and the firebrick thickness is 20 cm. If the convective heat coefficient of the outside air is h=15 W/m2-K, what is the temperature of the interior wall of the kiln?

Question

1. please write clean and as much detail as you can

2. please draw the FBD since I am not understanding the temperature placement on this question

3. to make your job easier the following formula apply :

Q_cond=Q_conv+Q_radi

KA(T_i-T_o )/L=hA(T_s-T_∞ )+ε σ A(T_s^4-T_∞^4 )

Qcond = Qconv + Qradi КАТ - То) i = hA(T, – T) + E o A(T – T%) S L
Transcribed Image Text:Qcond = Qconv + Qradi КАТ - То) i = hA(T, – T) + E o A(T – T%) S L
