【Daily Question】Chemical Engineering Principles 156: Pipeline Friction (August 29)
Thread Content
This post was last edited by “Back to Cambridge” on September 22, 2015, at 10:26. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Engineering Thermodynamics”, and “Chemical Process Technology” will be introduced. We hope for your active support! 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~~~ Fill-in-the-blank question: When using a centrifugal pump to transfer fluid between two open containers, if the liquid levels in both containers are kept constant, reducing the valve opening in the delivery pipeline will cause the total resistance in the pipeline to ___________. unchanged
When the valve of the delivery pipeline is closed, the total resistance of the pipeline will __remain unchanged__.
When transferring fluid between two open containers using a centrifugal pump, and if the liquid levels in both containers are kept constant, reducing the valve opening in the transfer pipeline will cause the total resistance in the pipeline to ___________. Grow larger
When transferring fluid between two open containers using a centrifugal pump, and if the liquid levels in both containers are kept constant, reducing the valve opening in the transfer pipeline will cause the total resistance in the pipeline to _____decrease______.
When transferring fluid between two open containers using a centrifugal pump, and if the liquid levels in both containers are kept constant, then when the valve in the delivery pipeline is closed, the total resistance in the pipeline will ____ remain unchanged _______.
Uh. Could it be that the total resistance of the pipeline mentioned does not include that valve? .
When transferring fluid between two open containers using a centrifugal pump, and if the liquid levels in both containers are kept constant, then when the valve in the delivery pipeline is closed, the total resistance in the pipeline will ____ remain unchanged _______.
When transferring fluid between two open containers using a centrifugal pump, and if the liquid levels in both containers are kept constant, reducing the valve opening in the delivery pipeline will cause the total resistance in the pipeline to ___________ decrease
Unchanged! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
When transferring fluid between two open containers using a centrifugal pump, and if the liquid levels in both containers are kept constant, reducing the valve opening in the transfer pipeline will increase the total resistance in that pipeline.
