Steady-state Heat Conduction in Planar Walls: Summary
The answers to the ConcepTests are given below and will open in a separate window.
Key points from this module:
- The temperature gradient at an insulated wall is zero (i.e., dT/dx = 0).
- The temperature gradient within a uniform wall without heat generation at steady-state is linear (i.e., dT/dx = constant)
- For walls connected in series without heat generation and at steady state, the rate of heat transfer is the same through each wall.
- For two walls in series, for steady state conduction through the walls.
- Contact resistance where two wall join results in a temperature drop between the walls.
