Unformatted text preview: dy. Consider 1- D conduction in the compound plane. (a) Draw an appropriate control volume for compound plane and write the energy balance equation. (b) What is the value of constant heat flux q”? (c) Is radiation significant? Why (not)? (d) Calculate the temperature at the interface of A and B and the bottom surface at steady state. Neglect any contact resistance. 2. A cylindrical rod of diameter D = 25 mm and thermal conductivity of k = 100 W/m.K protrudes normally from a furnace wall that is at Tw , and is covered by an insulation of thickness L1 = 200 mm. A uniform heat flux of 45 kW/m2 escapes through the furna...
