Problem
A 12 mm composite panel is formed by stacking three layers in contact over the same cross-sectional area: 2 mm of copper (thermal conductivity 400 W m⁻¹ K⁻¹), 4 mm of plastic (thermal conductivity 0.30 W m⁻¹ K⁻¹), and 6 mm of glass (thermal conductivity 1.1 W m⁻¹ K⁻¹). Calculate the effective thermal conductivity of the entire 12 mm panel, assuming one-dimensional steady-state conduction. Give your answer in W m⁻¹ K⁻¹.
