Problem #1: A composite wall is constructed from 2 cm stainless steel (k = 10 W/m.K), 5 cm c corkboard (k = 0.1 W/m.K) and 1cm of plastic (k = 0.01 W/m.K). 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 100 C and the plastic surface is at 20 C. d) What are the temperatures on each side of the corkboard under these conditions?

Important instruction: This question uses the last three-digit value (L3D) of individual student matrix number. For example, if the matrix number is CD180264 then the L3D value is 264 (since the last three digits is 264).
