Consider one-dimensional conduction in a composite flat wall. The external surfaces are exposed to a fluid at 25 °C with a heat transfer coefficient of 100 W/m²K. In the intermediate wall B, there is uniform heat generation, while no generation occurs on walls A and C. The interface temperatures are T1 = 260 °C and T2 = 210 °C. Assuming negligible contact resistance at the interfaces, determine the volumetric heat generation and the thermal conductivity of wall B. kA= 25 W(m*K) LA= 30 mm kC= 50 W(m*K) LB= 30 mm                                         LC = 20 mm

Question

Consider one-dimensional conduction in a composite flat wall. The external surfaces are exposed to a fluid at 25 °C with a heat transfer coefficient of 100 W/m²K. In the intermediate wall B, there is uniform heat generation, while no generation occurs on walls A and C. The interface temperatures are T1 = 260 °C and T2 = 210 °C. Assuming negligible contact resistance at the interfaces, determine the volumetric heat generation and the thermal conductivity of wall B.

kA= 25 W(m*K) LA= 30 mm

kC= 50 W(m*K) LB= 30 mm
