Problem \#1: A composite wall is constructed from 2cm stainless steel (k=10W/m.K),5cm of corkboard (k=0.1W/m.K) and 1cm of plastic (k=0.01W/mK). a) Draw the thermal circuit for the steady state conduction through the wall. b) Evaluate the individual thermal resistance of each material layer. c) Determine the heat flux of the surface of steel is maintained at 100C and the plastic surface is at 20C. d) What are the temperatures on each sidee of the corkboard under these conditions
