@d@r$h@n CF force is acting on the pipes, not the water, since the water isn't in a centrifuge. As you'll notice, it's travelling the centrepetal path hence why you see the centrifugal illusion. (Ie the water shoots to the middle therefore passing the middle and passes the outer circumference... not because it's spinning)

Ofc Steve was right. He had already tried the home-made sprinkler before you arrived to UK. Steve might be smart but clumsy as well. he could at least had changed his clothes to a summer outfit and flip flops to prevent soaking his jeans and shoes. who wants to walk around with clothes all soaked?

I think the confusion between Steve and Destin is that Destin is thinking about "streamlines" (instantaneous particle velocity field) and Steve is talking about 'streaklines" (the...well its hard to describe...the path created by a bunch of 'streamlines" as the location of the source changes in time).

This is one of the better videos I have seen in a while. First off, it travels in a straight line was my takeaway. But the bigger takeaway is, we only become stupid when we shut our brain down. Not turn it off, but more so when we block the acceptance of information.

Hi Destin, I have a question about this video. You sometimes said something along the lines of "we're looking at the snapshot". So now to my question how is the snapshot different from "the not snapshot" both physically and logically?

Audio-books, sure. But please stop promoting the use of them behind the wheel. When listening to audio-books, you cannot compare it to background music on the radio. You're not going to listen to an audio-book that doesn't matter to you. So the topic matters and you want to listen. Even a phone conversation, where you can interrupt, stop talking or ask the other person to repeat what they said, has been proven over and over again to be a genuine and massive distraction that effectively causes accidents by the millions each year. So you must understand that listening to an audio-book, that keeps on talking and will make you miss something if you are not listening properly, definitely takes a way a huge portion, and most likely your main focus, off the road. My life got destroyed by somebody who was driving while his focus was impeded. Please, don't create more distractions, don't create more killers... Thank you.

Important to note that centrifugal force on the water exiting the nozzle creates negative/zero pressure in the first scenario and positive pressure in the second scenario. This changes how much of the rotational energy is delivered to the water droplet as either radial or tangential velocity.

another variation I want to try is what happens when the jet is pointed opposite the "bend" in the stream. I am sure a force diagram would predict it.
Robert ONeill
Robert ONeill Před 12 dny
I wonder what would happen when the rotational speed increased. My theory (without force diagraming) is it will bend further outward.

Mindblowing. I'm curious what other shapes would do. What would happen if you fork those 4 pipes pointing inward, the end of the pipe would look like this: -< One stream would go with the rotation and the other would go against the rotation. I think the following shapes would also produce funky results. My suggested experiments would be: -( (an splitter with inward bend) -< (a splitter + straight bend), -= (another straight bend with possibly different results), -C (an extreme inward bend) and one where the forks bend "outward", Υ

W=V/R Tangential velocity of the spout and the droplet is the same, since the droplet is intertial after leaving the spout, but in the outwards case droplet's radius in increasing, so angular velocity is decreasing, causing jets to "lag" behind. In inwards case it is the opposite.

Aryak Sathye
Aryak Sathye Před 29 dny
I mean since the water particles at any instant are rotating around the center but also moving radially, they will experience a tangential force making them appear to either lag or lead the spinning water spouts

Tyler Ivey

I feel like an opportunity was missed by not drawing a circle around the final model. Once the water exits the drawn circle, because only one direction of force changes, it repeats the original shape of force direction that causes the lagging effect in the first model. Wouldn't there be a speed where the final model's water jet hits a tangent on the circle and does repeat the same force direction?

OK with the nozzles facing inwards (meaning the exiting water from the nozzle is parallel to the surface of rotation), is there a rotational speed or a nozzle design or configurations( i. e. bending, twisting the tubes) where no water flow is possible for a given water preasure?

I would really have liked to see what would happen if the jets were slightly angled, just enough for them to provide their own spin, like the sprinkler, and see if they'd come out appearing to go backward, and then curve around to appear to be traveling foreward, relative to the sprinkler heads.

I just wanted to say, I rewatched this a year later, and after having gotten into a whole lot of disagreements with people in the past year, I think I need to relearn whatever you said in 9.51. I'd like to have that kind of humility. I'd like to think I'm the most astute of critical thinkers out there but sometimes by the time I get to it I'm all shut down and only too ready to disagree. I'm only too ready to call that out in someone else esp if they disagreed with me but, I think I should also take time to pause each time I disagree too. Not just on physics, especially on politics. Maybe the freedom of speech isn't the freedom to say whatever the f*** I want, but the responsibility for me to listen when someone else speaks. Esp if I disagree.

amitamit 997
amitamit 997 Před měsícem
To everyone else who is confused: in both cases the vector was to the direction of rotation, so how do the water in the first case "lag behind" and in the second it seems like they move faster than the rotation? That is because in the second case they got their speed from the outer edge of the rotation, and because they move closer to the center (that moves slower than the outer circle) they "pass" it.

First Sprinkler: Once the water leaves the spout there is no Coreolis force to accelerate it tangentially that’s why it lags behind the sprinkler arms as it moves radially outward. Each particle has the same tangential velocity as it had when it left the nozzle. The drops would have to accelerate tangentially (via Coreolis force) to keep up with the arm as the drops move away from the centre of rotation. Once the drops leave the nozzles they travel in straight lines. Second sprinkler. This is the exact opposite of the first case. The flow appears to lead the arms because the water has the tangential velocity that it had when it left the nozzle. There is no Coreolis force to slow the water’s tangential velocity to match the arms. Since the tangential velocity at the nozzle is bigger than nearer the axis the water leads the arms.
