The last edit to this post was made by Zaihui Kangqiao on 2015-12-5 at 14:25. 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 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\" activity can be viewed directly, and the thread will be closed after 1 day ! You receive 3 wealth points for simply participating, and an additional 3 wealth points if you answer correctly. Multiple-choice question: When water flows in a circular straight pipe at a constant velocity, if the diameter of the pipe is doubled, the friction loss will be ( ) of the original value. A. 1/4 B. 1/2 C. 2 times A
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes (A. 1/4) of the original value.
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes A. 1/4 of the original value
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes (A) times the original value.
A、Quarter---------------------------------
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes (A) times the original value. A. 1/4 B. 1/2 C. 2 times
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes (A) times the original value. A. 1/4 B. 1/2 C. 2 times
I believe the correct answer to this question is A.
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes (A. 1/4) of the original value.
When water flows in a circular straight pipe with steady flow velocity, if the diameter of the pipe is doubled, the friction loss becomes (A) times the original value. A. 1/4 B. 1/2 C. 2 times
A, well, it’s a formula; let me think
