Question details
This is Mechanical Engineering Heat Transfer chapter 2/3. Thank you!

Answer the following questions: a. Draw the thermal circuit that represents the turncoat, labelling each resistance in the circuit. b. Compute the thickness of the thermal liner needed to protect the firefighter from receiving burns under these conditions. Problem 4 (Heat Sandwich 2: Electric Boogaloo) Consider again our sandwiched heater from Problem 2: Electric heater, q: P.Ck Fluid Fluid T., h -L +L We wish to re-do this analysis using thermal resistors. a. Draw the thermal circuit representing this entire problem (not just half of it!). Make sure to include the convection resistances on both sides of the plates. Assume the heater has no appreciable resistance for itself and there is no contact resistance. b. Use the thermal circuit to compute the temperature at the electric heater (i.e. x-). How does this temperature compare to what you computed in Problem 2 using the heat equation?
