(a) Show the thermal circuit representing the steady-state heat transfer situation. Be sure to label all elements, nodes, and heat rates. Leave in symbolic form.
(b) Assume the following conditions: = 20 , = 50 W/ and = 30 . Calculate the heat flux that is required to maintain the bonded surface at = 60
(c) Compute and plot the required heat flux as a function of the film thickness for mm.
(d) If the film is not transparent and all of the radiant heat flux is absorbed at its upper surface, determine
