【Daily Question】Fundamentals of Chemical Engineering 078: Multi-layer Heat Conduction (June 12)
Thread Content
The last edit to this post was made by Zaihui Kangqiao on 2015-10-29 at 14:23. The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series such as \"Principles of Chemical Engineering,\" \"Mass Transfer and Separation,\" \"Thermodynamics in Chemical Engineering,\" and \"Chemical Process Engineering\" will also be introduced. We hope for your active support! Answers to the questions in the \"One Question per Day\" activity can be viewed directly, and the thread will be closed after 1 day ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ True or False: In multi-layer heat conduction, the driving force is the sum of the driving forces of each layer, and the resistance is also the sum of the resistances of each layer. Wrong
In multi-layer heat conduction, the driving force is the sum of the driving forces of each layer, and the resistance is also the sum of the resistances of each layer. (Correct)
In the principles of chemical engineering, it is stated that: \"The total driving force for heat conduction through multiple parallel walls is the sum of the temperature differences across each layer, that is, the total temperature difference; the total thermal resistance is the sum of the thermal resistances of each layer.\" ”It seems the answer to this true/false question should be “true”.
In multi-layer heat conduction, the driving force is the sum of the driving forces of each layer, and the resistance is also the sum of the resistances of each layer. (right)
Correct~~~~~~~~~~~
In multi-layer heat conduction, the driving force is the sum of the driving forces of each layer, and the resistance is also the sum of the resistances of each layer. Error
In multi-layer heat conduction, the driving force is the sum of the driving forces of each layer, and the resistance is also the sum of the resistances of each layer. Answer: Correct
In multi-layer heat conduction, the driving force is the sum of the driving forces of each layer, and the resistance is also the sum of the resistances of each layer. (Correct)
Correct. The driving force refers to the sum of the temperature differences across the layers. Resistance refers to the sum of thermal resistances.
