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?

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a bur…
