So if you have a turbulent flow is the profile of the flow before the "entrance length" just some developing profile. Neither turbulent or uniform? I thought only parabolic profiles could be called fully developed.

At 30:00, the value of the Reynolds number is less than 2100 not more than 4000, which makes it a LAMINAR flow instead of turbulent flow....
@arham_mtl5 жыл бұрын
In the video the value of Re at @30:00 is 6369.44, which is greater than 4000. (i think you are confusing the " , " by a " . " ) Side note: Reynold's number is the ratio of inertial forces to viscous forces. When Re is small, viscous forces supress the inertial forces. When Re is greater, inertial forces are more than viscous forces, and thus the chaos. Reynold experimentally came up with the expression of Reynold's number. In doing so, he assumed some of the factors that affect laminar to turbulent transition to be insignificant. Some of those factors are surface roughness, pipe vibrations and fluctuations in upstream. These parameters are carefully manipulated in fluid mechanics labs to even get laminar flow at Re=1000. Also this 2100- 4000 transition range is only accurate for Circular pipe flow.

This would have been a most useful lecture if Prof. Biddle wasn't changing the results, (reversing them), after his explanations, (for example, @24.00, is the flow at the end of the entrance region now laminar or turbulent)! The use of prepared slides could have eliminated much of the time he spent copying equations from his lecture notes onto the blackboard. Obviously, John Biddle knows this subject; but, he could do better with some audio-visual aids. Also, why not record a lecture without a class of students to interrupt him, to walk past him, and to make distracting noises? Too busy to make a really good video lecture? I was intrigued, at first, by a lecturer who wasn't regurgitating the textbook's lesson, then was disappointed; with this classroom's distractive behaviours, I certainly would have dropped out of this course; and, I won't bother with the other "tutorials" in this series, (which could have been better staged and edited).
