Question
The composite wall of an oven consists of three materials, two of which are of known
thermal conductivity, kA = 20 W/m – K and kC = 50 W/m – K, and known thickness, LA =
0.30 m and LC = 0.15 m. The third material, B, which is sandwiched between materials
A and C, is of known thickness, LB = 0.15 m, but unknown thermal conductivity kB.
Under steady – state operating conditions, measurements reveal an outer surface
temperature of 600 oC, and an oven air temperature of 800 oC. The inside convection
coefficient h is known to be 25 W/m2 – K. total rate of heat transfer = 550 W/m2.What is the value of kB?
