The temperature of the two outer surface of a composite slab, consisting of two materials having coefficient of thermal conductivity K and 2K and thickness x and 4x respectively are T2 and T1 ( T2 > T1).
The rate of heat transfer through the slab, in a steady state is [ A (T2 - T1)K / x ] f, with f equal to:
(a) 1
(b) 1/2
(c) 2/3
(d) 1/3
