Subtopic: Steady state heat transfer in conduction, convection and radiation
Question Statement:
The thermal resistance of a composite flat wall consisting of two layers in series is the sum of their individual resistances ($R = \frac{L_1}{k_1 A} + \frac{L_2}{k_2 A}$). Layer 1 has $L_1 = 0.05\text{ m}, k_1 = 0.10\text{ W/(m}\cdot\text{K)}$. Layer 2 has $L_2 = 0.10\text{ m}, k_2 = 0.04\text{ W/(m}\cdot\text{K)}$. For a wall area $A = 1.0\text{ m}^2$, the total thermal conduction resistance in $\text{K/W}$ is ________ (answer in integer).
