@Kaiman_0076 3 месяца назад

So for your water draining question, I notice it's giving a little more priority to directly above the drain than to the sides of it

@PromptedHawk 3 месяца назад

That probably has to do with boundary layer stuff, but if you look closely towards the end of the draining (easier to see without the echo effect) you can spot that it still forms a little whirlpool, that might have something to do with what we see. On further thought, we see a larger amount of beads moving above the drain and staying there while the whirlpool forms, so it seems that it's in fact giving a little _less_ priority to the water directly above the drain. On further further thought, I may have completely misinterpreted your comment, actually. In the video, Steve says he was asked if water drains from the top down or something like that, and I was thinking of that question as well while replying.

@Irondragon1945 3 месяца назад

Here's a fluid dynamics question i had for years and never found a proper answer for, i dont think there's any videos on it either There's the thing you can do with bottles or jars to clean them, you partially fill them with water, then close them and shake. The question now is, how much water do you need to put in for the best cleaning effect? If it's too little, then the water doesnt have enough weight for a proper "impact", and if its too full then you cant build up enough speed for it to clean. What's the optimal volume for the best cleaning effect, and does it depend on the shape of the container? What other ways are there to increase the efficiency of that method? Of all youtube channels i watch I cant imagine any other being more suitable for this kind of question.

@bepamungkas 3 месяца назад

> What other ways are there to increase the efficiency of that method? if the bottle are long and have bigger base vs top: tilt ~30 to 45 degrees (depends on bottle shape) and rather than shaking it you spin it around and make use of both centrifugal force and leverage. since most gunk and residue are collected at the base of the bottle, which now are further away from center of rotation, the centrifugal force applied to them got amplified. It work best if the bottom of the bottle is concave instead of flat It will be harder to do with jar because their base vs top ratio are almost 1:1. You can close it, wrap the neck with strong rope, let it dangle and then spin it till the rope and jar is angled (similar to how centrifuge works in chemistry). But this usually not as efficient since your knot will likely be off-center of the jar center of mass and center of rotation.

@bepamungkas 3 месяца назад

Wait, i just remembered simpler method I usually use with smaller jars. fill 1/4 with water, close it, position perpendicular to floor in front of us (with both hand grabbing the top and bottom part) then do circular motion to induce centrifugal force. It's actually work better with less water since too much water will cause it to just slosh around. You can "aim" at certain part by tilting either hand.

@aidenaune7008 3 месяца назад

its about optimizing pressure and force. the more water there is, the more that the air inside cushions it before it hits the bottom. this is because the water more easily forms a seal and prevents the air from moving out of the way. with less water, no seal will form, but the water will still be pushed to the side by the air, causing it to slide more than impact. the optimal amount of water is proportional not to the size of the container, but to the square area of the plane perpendicular to the direction of motion of the water. the container can have a ridiculous volume, but so long as the axes you are not shaking through are small, then so will be the amount of water you can use. testing it myself, it seems to be about 3 inches of water.

6:30 In my perception, a 3d drain drags particles with increasing force related to the decrease in distance. Since angles are important in force transmissions and each particle has to push through a relative resistance a funnel shaped movement results, combining itself with the "coriolis principle" Ito a vortex (when disturbance is low enough) Hope this makes sense, since I am no professional! I just always loved to play with water, like creating vortexes with my hands or just watching it's reactions of flow to certain factors. :3

Can you use those beads to do small explosion, like a very small firework or something that won't do a great deal above the water but might show some of the expansion and contraction that happens. If you could get (I think they are called) pistol shrimp to do there thing with those beads I would love to see it. O, idea, maybe you could see something sort of like the pistol shrimp snap with water hammer in a glass coke bottle if the bottle doesn't break.
