@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)

G'day Destin, very interesting video. I'm no physics expert but I reckon you also need to consider centrifugal force experienced by the water drops impacting the angle in which those move forward. That's why you see a beautiful curve with a small nudge on the curved in sprinkler (as it cancels the part of velocity of water coming out)

Hey great vid but the explanation of why it happens lacks something imho. The reason why it looks like the water moves forward is because it actually does! Angular velocity at the tip of the sprinkler is higher than in any other point of it (center has 0), so as the water sprinkles to the center its position is always forward than the position of the sprinkler arms (because they have lower angular velocity)

I just started watching your channel, so I've gone back to watch all of your older videos. Sorry if someone already mentioned this, but you left out the centrifugal force on the water while coming out of the spout. If you spun the sprinkler hard enough, no water would come out because the centrifugal force would be stronger than the pressure, but anything in between causes the weird motion.

Isn't this just another way of thinking about/visualizing the rolling shutter phenomenon? Or maybe it is simply an issue of needing to be really specific about frame of reference when having these discussions. The direction of the stream ends up being very different than the direction of a single water molecule.

O-O and I was right =D The water would make that curve shape as the water should still be moving as fast as the nozzle of the pipe in the direction it left it, however since this time it's being shot inwards towards the centre of rotation the distance the water has to travel in accordance to the nozzle of the pipe it is being shot out, to stay straight and align itself with the pipe, the water's speed in which it must be moving ( not the speed it's being catapulted out but the speed caused by the centripetal force) must slow down, however in this case air resistance is not enough to slow it down for that to happen which is why the water overtakes the nozzle until it exists the circumference of the circle the spinning device encompasses ( and traces with the pipe nozzles ) where the water starts to then lag behind the spinning of the device which if you let the water fall for longer, will actually allow the water to start resembling the 'trailing' observed when it was ejected outwards away from the centre of rotation as it basically is at the point it exits the circumference >W

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.

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) - -= (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.

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

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?
