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. To =? hi =? Ti kB =? Air Toor h KA kgkc kB LA Under steady-state operating conditions, measurements reveal an outer surface temperature of Ts,o=20C, an inner surface temperature of Ts,i=600C. What is the value of kB? The flow is from A to C. LB complete integration and solution pls 5,0 Lc
