【Daily Question】Chemical Engineering Principles 112: Viscosity (July 17)
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 ! Participation earns 2 wealth points, with an additional 3 wealth points for correct answers~~~ Fill-in-the-blank question: The physical meaning of viscosity is the ___________ that drives a fluid to develop a unit velocity gradient.
