Physics · Transmission of Heat
A composite slab consists of two materials having coefficients of thermal conductivity K and 2K, and thicknesses x and 4x respectively. The temperatures of the two outer surfaces of the composite slab are T2 and T1 (where T2 > T1). The rate of heat transfer through the slab in a steady state is given by [A(T2-T1)Kx] × f, where 'f' is equal to:
