Consider a compound slab consisting of two different material having equal thickness and thermal conductivities `K` and `2K` respectively. The equivalent thermal conductivity of the slab is

A

`sqrt(2K)`

B

3K

C

`4/3`K

D

`2/3` K

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(eq)=(2K_1K_2)/(K_1+K_2)=(2K xx 2K)/(3K)=4/3 K`
