Discussion Forum : Heat Transfer, Refrigeration and Air Conditioning - Section 7 (Q.No. 36)
36.
A furnace is made of a red brick wall of thickness 0.5 m and conductivity 0.7 W/mK. For the same heat loss and temperature drop, this can be replaced by a layer of diatomite earth of conductivity 0.14 W/mK and thickness

k1/x1 = k2/x2,
0.7/0.5 = 0.14/x2,
= 0.07/0.7 = 0.1.
0.7/0.5 = 0.14/x2,
= 0.07/0.7 = 0.1.

For thick place homogeneous wall, heat loss = kA dt/dx or 0.7
