Acomposite wall consists of a 10-cm-thick layer of building brick of thermal conductivity k = 0.7 w/(m • °c) and 3-cm-thick plaster of thermal conductivity k = 0.5 w/(m • °c). an insulating material of thermal conductivity k = 0.08 is to be added to reduce the heat transfer through the wall by 70 percent. determine the thickness of the insulating layer.
