Heat and Mass Transfer A composite slab has two layers of different materials with thermal conductivities k₁ and k₂. If each layer has the same thickness, then the equivalent thermal conductivity of the slab will be k₁ k₂ (k₁ + k₂)/ k₁ k₂ 2 k₁ k₂/ (k₁ + k₂) (k₁ + k₂) k₁ k₂ (k₁ + k₂)/ k₁ k₂ 2 k₁ k₂/ (k₁ + k₂) (k₁ + k₂) ANSWER DOWNLOAD EXAMIANS APP
