【Daily Question】Chemical Engineering Principles 583: Stagnant Flow (July 10)
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 campaigns will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" – we hope you will give it your active support~~~ Answers to the \"One Question per Day\" questions can be viewed directly; the topic will be closed after 1 day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer: When a fluid flows stably in a circular straight pipe, its velocity distribution follows a _______ shaped curve; the maximum velocity at the center of the pipe is _______ times the average velocity, and the relationship between the friction coefficient λ and Re is ___________. parabola ； 2 times ； λ=64/Re
When a fluid flows stably in a circular straight pipe, its velocity distribution follows a _parabolic__ curve; the maximum velocity at the center of the pipe is __2__ times the average velocity. The relationship between the friction coefficient λ and Re is __λ = 64/Re__ _
When a fluid flows stably in a circular straight pipe, its velocity distribution is in the form of a _parabolic__ curve; the maximum velocity at the center of the pipe is __2 times__ the average velocity. The relationship between the friction coefficient λ and Re is __λ = 64/Re__ _
Parabola 2 = 64/Re
When a fluid flows stably in a circular straight pipe, its velocity distribution is a ___parabolic____ curve; the maximum velocity at the center of the pipe is ____2___ times the average velocity. The relationship between the friction coefficient λ and Re is ____λ=64/Re_______).
When a fluid flows stably in a circular straight pipe, its velocity distribution is parabolic in shape; the maximum velocity at the center of the pipe is _2_ times the average velocity. The relationship between the friction coefficient λ and Re is _λ = 64/Re_.
Parabola, 0.8, 64/Re
Parabola 2 λ = 64/Re
When a fluid flows stably in a circular straight pipe, its velocity distribution follows a _parabolic__ curve; the maximum velocity at the center of the pipe is __2__ times the average velocity. The relationship between the friction coefficient λ and Re is __λ = 64/Re__ _
_Parabola: _2_ times, _λ = 64/Re_.
