Answer» The temperature of the two outer surfaces of a composite slab, consisting of two materials having coefficients of thermal conductivities $K$ and $2 K$ , and thickness $x$ and $4 x$ respectively are $T_{2}$ and $T_{1} (T_{2} > T_{1})$ as shown in figure. The cross-sectional area of the slab is $A$ . The rate of heat transfer through the slab in steady state is $[\frac{A (T_{2} - T_{1}) K}{f x}]$ , where $f$ is equal to
