A series of composite wall of a furnace consists of 20cm of firebrick, 15cm of a  high temperature insulating material, 12cm of ordinary brick, and lastly, 8mm of  asbestos cement board. The inside of the furnace wall is 100C. Determine the heat  transfer through the wall per m². Firebrick k=1.4W/m-K High temperature insulation k = 0.22 W/m-K Ordinary brick k = 0.90 W/m-K Asbestos k = 0.39 W/m-K
