A thought experiment for you: 1. Fill the container with iron dust. 2. Carry out the same experiment as shown in this video. 3. Assume that the iron dust somehow became a sold chunk of iron, but maintained the shape. At this point, the iron chunk is in complete contact with the slanted faces. The bottom surface is in contact with the weighing machine. 4. Repeat step 2. Do you see any difference? 5. How do these two measurements differ from the case involving water (multiply the reading with water with the relative density of iron)? Did "internal grip" affect your observation?

@aj_mcnamara 19 күн бұрын

Well, the comparison to a solid object is a mistake in the first place as it confuses weight with pressure. The larger water body would still weigh more, just as a solid object would. To make a comparison for solid objects under pressure, you'd have to compare them under a compressive load. It would far less easy to intuitively show in a short, but more accurate.

Then how about Bernoulli's equation? The equation represents when the fluid matters flow through the smaller place, its pressure and velocity increases. And of course, the mass(amount) of the fluid is also great factor of this equation. But this video says there is no any difference on the pressure when the same type of fluid is in the different shaped-structures. Can someone explain me why?

@domenicolanza130 3 ай бұрын

The Bernoulli's equation is for fluid dynamics. Stevino's law(the one used here, that says dP/dz=-rho) is for fluid static. Here we're analyzing fluid static, so when we have equilibrium

@SHLee14 3 ай бұрын

@@domenicolanza130 Hi there. I still can't understand the difference between hydrostatic and hydrodynamics. A fluid at rest also has the property of falling down because it is affected by gravity, just like a flowing fluid. So the difference between the two is related to a container of fluid? (The downside of container in the video is certainly blocked I think)

@domenicolanza130 3 ай бұрын

@@SHLee14 hi, the two equation are approximations(e.g. incompressible fluid) for different situations. It is important to distinguish the two cases in the derivation because certain terms disappear. If you want to analyze a situation like the one in the video, where everything is still/fixed/static, we are in hydrostatic, and we can explain why everything is static (from the Stevino-law). If a fluid is moving, you can use the Bernoulli's equation. It's true that the Fluid could move, but as you stated, the gravity force is balanced by some reaction of the container, so the situation is static. In general, you should always consider movement (like when in dynamic you consider an acceleration), and in fact, if you use the Bernoulli's equation here, with v=0, you obtain the Stevino-law. But here the fact that v=0 is assumed since that you can see that the Fluid is static. Hope this clarifies a little bit.

Fascinating, so no matter how deep you go in the ocean, as long as it's the same distance, I'm assuming the amount of pressure would stay relatively consistent?

@MarkusAldawn 3 ай бұрын

I strongly suspect the answer is "no," but if you were to add very tall towers of water to either side of the central column and close them up in glass so the water can't flow out, would the pressure in the middle column still be low since the water added is to the sides? I suspect this has to do with the fact that the water pressure wants to equalise, which may be why the example presented in the video takes place- there is X amount of water pressure to distribute, and by distributing it more thinly, the water adds the same amount of pressure downwards as it provides outlets for the pressure. So it... evens out? Not sure I understand the deeper level of this example, but it certainly seems obvious now that I've heard it.

@AXKfUN9m 3 ай бұрын

It's crazy how many people don't believe it despite being easily reproducible. To make the video clearer, the weight of the side liquid is acting on the walls of the containers, so if the measurements aren't done inside the liquid but outside there'd be more pressure on the left one. Another point is that 'liquid above it' is referring to the vertical distance from the point being measured to the surface.

@harvey854 3 ай бұрын

Here's how I like to think about it. Imagine if you replaced the water in the video with two blocks of steel in the same shape, and removed the containers. Then obviously the left one would exert more force, because the metal on the sides is stuck to the column and pulls down on it. But in the case of water, the stuff on the sides is not attached and does not pull down. That's why the pressures are the same

@penguinkeyss 3 ай бұрын

It's the same as the ocean, you don't feel all of the ocean water's pressure because you're in the ocean, you just feel what's above you. And that is a really good way to think about things, if you don't know immediately, try to exaggerate it massively or make it really really small and see what would make the most sense.

Crazy how we can decrease the water pressure at the bottom of a container by increasing the amount of water in it. This is because the pressure at the bottom of the container is directly proportional to the height of the water column above it. So, by increasing the water volume, you distribute the pressure more evenly throughout the container, reducing the pressure at the bottom.
