The thermal conductivity of a sheet of rigid, extruded insulation is reported to be k = 0.029 W/m. K. The measured temperature difference across a 20-mm-thick sheet of the material is T₁ - T₂ = 10°C. (a) What is the heat flux through a 2 m x 2 m sheet of the insulation? b) What is the rate of heat transfer through the sheet of insulation?
