Question
The temperature drop through layer furnace wall is 900oc. Each layer is of equal area of cross - section. Which of the following action(s)will result in lowering the temperature θ of the interface ?


Options
A.By increasing the thermal conductivity of outer layer.
B.By increasing the thermal conductivity of inner layer.
C.By increasing thickness of outer layer.
D.By increasing thickness of inner layer.
Solution
By increasing thickness of inner layer.Rate of heat flow
Now, we can see that θ can be decreased by increasing thermal conductivity of outer layer (K0) and thickness of inner layer (li).
