【Daily Question】Chemical Engineering Principles 154: Overall Heat Transfer Coefficient (August 27)
Thread Content
This post was last edited by “Back to Cambridge” on September 22, 2015, at 10:28. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity to help everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! For the “Question of the Day” activity, answers can be viewed directly in the replies; however, the thread will be closed after one day ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ True or False: The overall heat transfer coefficient K can be used to indicate the intensity of the heat transfer process, and it is independent of the properties of the cold and hot fluids. Wrong
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 cold and hot fluids. This is correct; K is only related to the thermal resistance of the heat exchange tubes, the diameter of those tubes, and their thermal conductivity
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 cold and hot fluids. (Wrong)
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 cold and hot fluids. (Mistake)
True or False: 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 cold and hot fluids. Error
Wrong. It is closely related to fluid properties, flow patterns, and disturbances.

True or False: 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 cold and hot fluids. ( Wrong )
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 cold and hot fluids. (Correct)
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 cold and hot fluids. (×)
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 cold and hot fluids. Yes
