engineering recuitment GATE ME 2023-24 Test Series Heat Transfer Conduction Fourier Law and Thermal Conductivity
A composite slab has two layers of different materials having thermal conductivities k ad 2k. If each layer has the same thickness, the equivalent thermal conductivity of the slab is
1
3k
2
\(\frac{k}{2}\)
3
\(\frac{3}{2k}\)
4
\(\frac{4k}{3}\)
