Consider a compound slab consisting of two different materials having equal thicknesses and thermal conductivities K and 2K, respectively. The equivalent thermal conductivity of the slab is

Multiple Choice Options

A $\frac{2}{3}K$
B $\sqrt{2}K$
C 3K
D $\frac{4}{3}K$

Step-by-Step Verified Solution

In series, equivalent thermal conductivity K e q = 2 K 1 K 2 K 1 + K 2 _ K e q = 2 _ K _ 2 K K + 2 K = 4 3 K
