【Daily Question】Principles of Chemical Engineering 091: Heat Transfer Coefficient K (June 26)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope for your active support! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly by replying, and this thread will be closed after 1 day ! You get 2 wealth points for participating, and an additional 3 wealth points for answering correctly~~~ Multiple-choice question: Which of the following statements about the heat transfer coefficient K is incorrect? A. In the heat transfer process, the overall heat transfer coefficient K is actually an average value ； B. The overall heat transfer coefficient K varies depending on the chosen heat transfer surface ； C. The overall heat transfer coefficient K can be used to indicate the intensity of the heat transfer process, and it is independent of the physical properties of the hot and cold fluids ； D. To increase the K value, it is necessary to start by reducing the maximum thermal resistance ； C
Why is it independent of the physical properties of hot and cold fluids?
C. The overall heat transfer coefficient K can be used to indicate the intensity of the heat transfer process, and it is independent of the physical properties of the hot and cold fluids；
