10-2.Transmission of Heat
normal
The temperature drop through each layer of a two layer furnace wall is shown in figure. Assume that the external temperature $T_1$ and $T_3$ are maintained constant and $T_1 > T_3$. If the thickness of the layers $x_1$ and $x_2$ are the same, which of the following statements are correct.
A
$k_1 > k_2$
B
$k_1 < k_2$
C
$k_1 = k_2$ but heat flow through material $(1)$ is larger then through $(2)$
D
$k_1 = k_2$ but heat flow through material $(1)$ is less than that through $(2)$
Solution
$\frac{d Q}{d t}=K A \frac{d \theta}{d x 0}$
$\frac{d \theta}{d x}=$ slope of graph $\alpha \frac{1}{K}$
