【Daily Question】Chemical Engineering Principles 142: Centrifugal Pumps (August 15)

2015-08-15View Original

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 to the post, and the topic will be closed after 1 day ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ True or False: If centrifugal pumps of the same model and at the same rotational speed are used for performance testing in a pipeline with high resistance and one with low resistance, the resulting performance curves of the pumps will be different ( ). The maximum flow rate of their actual supply pipelines also varies (). Wrong, right

When centrifugal pumps of the same model and at the same speed are used for performance testing in a pipeline with high resistance and one with low resistance, respectively, the resulting performance curves for those pumps will be different (×). The maximum flow rate of their actual supply pipelines also varies (√).

The first is “the same”, the second is “different”.

The performance curve of the pump detected is different (error), and the maximum flow rate in its actual supply pipeline is also different (correct).

If centrifugal pumps of the same model and at the same speed are used for performance testing in a pipeline with high resistance and one with low resistance, respectively, the performance curves obtained for these pumps will be different (incorrect). The maximum flow rate of their actual supply pipelines also varies (correct).
