I know it's a joke and all, but fully understanding these would at most put you at an undergrad level. Master and Ph. D are about use this knowledge to research and understand more.
urbanturbine I remember in my hydraulics class, we just threw a stick in the water and timed how long it took it to float downstream. Rubber duck is probably better. More visible.
As a Civil Engineer myself, I wish my professors taught me these with these examples. I would have continued as a Civil Engineer instead of moving to Information Technology.
It is not true, this level rising and slower velocity is from local energy losses. The slope. Of the river is higher in upstream and therefore velocity is higher. Downstream slope is slighter, velocity is reduced. Model is showing constant slope!!
I've always wondered in geo classes that if a simple obstacle really rises the water level that much and effect so far away. This is perhaps the most intuitive resource to understand it. Fantastic video
Love how you guys illustrate how the water will actually behave...so clear and easy to understand. I never thought I would ever need to know this but recently I have been making a table top fountain project and the water flow speed was too slow and that's when I thought of this video and came back to look for you guys.
Jonathan Rabe its the other way around. Mechanical Engineers more likely to have models and prototypes. Civil Engineers only get one chance as every location is unique.
This reminds me a lot of my casting classes. We did a lot of fluid flow simulations to design molds for castings. A man named Dr. John Campbell took some xrays of castings while they were being poured, and found that water is actually a pretty good analog for molten iron. So some of the models people use to demonstrate casting techniques look a whole lot like what you're using there :)
so I've always wanted more of the coastal defence videi that I have watched like 10 times everytime It pops up on my youtube now I am saying we need more of these types of water mechanics videos
Another knowledge explained very briefly.. well done JBA Trust, you showed things that other people might not know that happens in their everyday life.. very good engineering info that would save many people in some developing countries..
Yep but he always gotta fix what others don’t, so as soon as I saw culvert I was like « yeah send more maintenance for those so that post 10 can focus on unclogging others stuff »
Can I just add this is a fantastic video, I'm a white water kayaker and loved the explanations of all the different types of weirs etc. Wish they were building them more with recreational use in mind.
For civil engineers, this is a great way to demonstrate how Water Resources Engineering works! It is hard to believe, otherwise, by just working through formulae.
No ducks were harmed during production of this video. :) - It is very instructive and i am glad for two things - its in british language and you are using centimeters :)
What you call a "stopper" is known as a drowning machine, tom scott has an excellent video about them Also the duck getting stuck in diving is called a delta p event and a grate or screen is far safer then a hole as there is still flow with a hole you're body will block the hole and form a seal making you stuck there and probably die, delta p is horrifying
These videos show up in my recommended, I never search for them, but I have to say, this is very interesting and I love to learn about this kind of water physics.
RU-vid Ai, you have to learn to read my comments, understand them and keep suggesting me such great informative content🙏. This was the best video I've seen in months!!
I have been looking for information on how to represent these structures in a hydraulic model and this has proved to be very useful in helping me understand what I am doing. Please keep up the good work!
I watched this video a few weeks ago, who knew that I’d need to find it again, along with your other videos to showcase fluid dynamics and Bernoulli’s principle!
I remembered seeing this video a couple years ago and could not remember to name of it, I searched for about 20 minutes after remembering that I need to know that title and I was not disappointed
Great! It is in fact the simplest way. The professors did not show me easily when I was in school. It's good that I watched this video. Sorry, my english is so bad
How to: Make a practical learning video Demonstrate practical techniques Teach in an entertaining way Teach while also giving real world examples, their consequences, and what to watch out for My man/woman. I'm a CS major, but this has me both learning and entertained. If I ever do animations or scenery for a game/movie, or if I ever write a story, it's details like these that are so important, and if for some odd reason I completely change majors, this is still super helpful. Thanks guys :D
I can only imagine how much better education would have felt for me if every theoretical problem my teacher presented to me on the blackboard were backed up with equally good models on his desk.
