【Daily Question】Chemical Engineering Principles 214: Multi-layer Planar Walls (October 26)

2015-10-26View Original

Thread Content

The Chemical Engineering Theory section is launching a \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, series such as \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering\" will be introduced. We hope for your active support! True or False: In steady-state heat conduction through multiple parallel plane walls, the driving force is the total temperature difference between the inner and outer surfaces; the total thermal resistance is the sum of the reciprocals of the individual thermal resistances. ( ) Wrong

In the steady-state heat conduction of multi-layer planar walls, the driving force is the total temperature difference between the inner and outer wall surfaces; the total thermal resistance is the sum of the reciprocals of the thermal resistances of each layer. ( × ) The reciprocal of the total thermal resistance is the sum of the reciprocals of the thermal resistances of each layer

The correct answer to this question is wrong; I remember having seen this question before.
