Why does the water of the water nest turn, and it is clockwise

Here are the other brothers, I hope it will be helpful to you:

In the 40s of the 20th century, the scientist Kapiro noticed that the vortex formed at the leak always rotated in a fixed direction when he poured sewage into the sink after each experiment, and this phenomenon attracted his attention. So he deliberately stirred his fingers in the opposite direction when the water flowed, but the vortex returned to its original direction of rotation after the hand left. Does this have anything to do with the shape of the drain?

So he made many different shapes of leaks, but the results were always the same. Puzzled by this, he traveled all over the world to do the same experiment, and to his great amazement, the direction of the current vortex in the southern hemisphere was exactly opposite to that in the northern hemisphere, counterclockwise in the northern hemisphere and clockwise in the southern hemisphere, almost half of both cases near the equator. Capiro was overjoyed, and he finally found the conclusion that the direction of the original vortex was related to its position on Earth.

This phenomenon was later known as the Capilo phenomenon.

In fact, the Capilo phenomenon is caused by a so-called Coriolis force caused by inertia during the rotation of the Earth. In the Northern Hemisphere, this deflection force is to the right, causing the water to form a counterclockwise vortex as it flows downward. In the Southern Hemisphere, it is just the opposite clockwise.

Another form of Capillo phenomenon in nature is tornadoes. Whether it is landspouts and seaspouts produced in the vast plains or the vast oceans, it is found that in the Northern Hemisphere their direction of rotation is mostly counterclockwise. The Foucault pendulum in the Beijing Planetarium rotates clockwise every 37 hours and 15 minutes, which is also the result of the Coriolis force.

The Coriolis force is an important force that is easily overlooked by the average person. For example, the pressure on the right track is greater when the train travels rapidly from south to north in the northern hemisphere, and the east bank of the river from south to north is more heavily scoured, all of which can be explained by the Coriolis force, and the influence of the Coriolis force should also be taken into account in the launch of long-range missiles, weather forecasting, navigation, and the design of bubble levels in aviation.

Due to the geostrophic deflection force, you can also use a rope to hang a heavy object and make it swing from east to west, after which it will swing from north to south.

Because the Earth is rotating, the vortex formed by the water in the tank rotates in the opposite direction in the Southern Hemisphere and in the Northern Hemisphere, and the Brocade pendulum can prove that the Earth is rotating.

Because the earth is rotating. And you're in the Northern Hemisphere, and if you're in the Southern Hemisphere, pull counterclockwise.

Because of the geostrophic deflection force, the motion of an object in the Northern Hemisphere is subject to a rightward deflection force, and vice versa in the Southern Hemisphere.

The situation you said is that when the water is still at the beginning, this is the case, but if it is pouring water, that is, the water is moving at the beginning, it is not necessarily, I don't believe you try.

Subject to geostrophic deflection force. The Northern Hemisphere is losing positive.

It can be both clockwise and counterclockwise, as the Earth is affected by the geostrophic deflection force. The water in the Northern Hemisphere experiences a force to the right, so it is turning clockwise. Whereas, the Southern Hemisphere experiences a force to the left, so it is counterclockwise.

Due to the geostrophic deflection force, when the object moves perpendicular to the earth's latitude on the earth's surface, because the earth's rotation linear speed changes with latitude, due to inertia, the object will have a tendency to maintain the direction of motion of the original speed relative to the ground, which is called geostrophic deflection force.

In the Northern Hemisphere, the object moves from south to north, the linear velocity of the Earth's rotation becomes smaller (the linear velocity is the largest at the equator), and the object is biased to the east due to inertia to keep the linear velocity unchanged, and the relative direction of motion is to the right.

When moving from north to south, the linear velocity of the Earth's rotation increases, so it is biased to the west, and the relative direction of motion is also to the right. Therefore, when the object in the northern hemisphere moves, it is uniformly subjected to the rightward geostrophic deflection force. In the same way, objects are uniformly subjected to a leftward geostrophic deflection force when moving in the southern hemisphere.

Due to the different directions in which the water begins to flow, the walls in the pool are tilted at different angles, and as soon as the water flows, a whirlpool is formed. As soon as the water rotates, the centrifugal force kicks in, and even in opposition to the Coriolis force, it accumulates with the deflection effect, forming a vortex that coincides with the initial direction of rotation.

Some people say that it is caused by the spin of the earth, but I personally think it is very small.

Mainly caused by the structure of the pool, the pool is generally similar to the shape of the funnel on the top and down, the leakage is a certain cone, when the drain valve is manually opened, the place where the water must be opened first will flow first, and the other parts will flow later, this imbalance produces swirl.

It seems advantageous to swirl this way, as it increases the flow rate, reduces the discharge time, and increases the water's ability to carry magazines.

It can be clockwise or counterclockwise, because, when the water valve is opened, one part is opened first, so the water on the side that is opened first will naturally flow down first, and then the other parts will flow down, so this is not certain.

Because the earth is affected by the geostrophic deflection force. The water in the Northern Hemisphere experiences a force to the right, so it is turning clockwise. Whereas, the Southern Hemisphere experiences a force to the left, so it is counterclockwise.

Because of the eccentric force caused by the rotation of the earth, and because there is a southern hemisphere and a northern hemisphere, the direction of the vortex is different.

Not necessarily, it is a mistake to say that the rotation is different in the northern and southern hemispheres.

It can be both clockwise and counterclockwise.

Because the earth is affected by the geostrophic deflection force.

Pseudoscientific answers are recommended! Litter.

Resurrection nail slimy u hahaha.

The whirlpool formed by the current rotates counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. When we use a washbasin or toilet bowl to drain water, the water usually flows out of the drain hole in a whirlpool.

In fact, it is not only the whirlpool, the right bank of the river is much more washed by the current than the left bank; The winds blowing from north to south on the earth always turn to the east wind; The rotation of tornadoes is due to the influence of geostrophic deflection forces. Physics calls this force the Coriolis force.

It can be both clockwise and counterclockwise. His reasons:

The Coriolis effect is true when explaining fluids that move on a large scale, such as ocean currents and atmospheric circulation. But using the Coriolis effect to explain water vortices is a big mistake.

This vortex is related to the rotation of the Earth. The Earth is constantly rotating from west to east, and the United States is in the Northern Hemisphere, which causes the bath water to rotate in a counterclockwise direction. In the Southern Hemisphere, it rotates clockwise, and at the equator it does not form a vortex! Hope it helps you.

When a flush toilet flushes, the flow of water creates a whirlpool that flows down the drain hole. It has been theorized that in the Northern Hemisphere, the water vortex is clockwise; In the Southern Hemisphere, it rotates counterclockwise. And the reason for this phenomenon is due to the rotation of the earth.

In fact, the role of the Earth's rotation is very weak, so it is difficult to influence the direction of water flow. You can easily verify this in some washrooms, whether counterclockwise or clockwise, and the direction of the swirl depends on the structure of the sink, not the northern and southern hemispheres.

Counterclockwise in the Southern Hemisphere and clockwise in the Northern Hemisphere. This is caused by the rotation of the Earth, which forms a geostrophic deflection force that affects the direction of the flow of water. For example, the flow of the Yangtze River is affected by geostrophic deflection forces, and the channel of the Yangtze River at its estuary is constantly drifting southward, and in the north it is constantly accumulating to form an estuary delta.

However, the geostrophic deflection force is indeed weak, and the changes in the Yangtze River estuary are caused by many years. Therefore, in theory, the flow of water in the toilet bowl is affected by the structure of the sink.

Earth's gravitational pull. And the earth is rotating and revolutionizing.

You know how the earth turns, right? In the Northern Hemisphere and the Southern Hemisphere, the flow of water is different! Knowing how the earth turns will know the answer.

Whirlpools are mostly formed because of sudden changes in the speed and direction of the current. For example, in a sharp bend in a river, because the water still flows in a straight line, but the river bank forces the water to bend, when the inner water is squeezed back due to the pressure on the outside, part of the water will come back to fill the dehydrated area, forming a whirlpool. In addition, whirlpools can also occur near bridge piles or large boulders emerging from the water.

When it goes around behind the obstacles, because the river here flows slowly, the current will hit the river that is blocking its flow, and when it turns around, there will be a whirlpool. This phenomenon has nothing to do with the nature of water and is entirely due to the rotational motion of the Earth. The Earth is a slightly flattened sphere that rotates from west to east at a rate of one rotation every 24 hours.

The circumference near the equator is much longer than the circumference near the north and south poles, but they must also complete their rotation in twenty-four hours; It follows that the speed of rotation is not the same in all parts of the earth. In the Northern Hemisphere, where we live, the further south we get closer to the equator, the faster the rotation; Conversely, the northerly the location, the slower the speed. All objects on the Earth's surface are affected by the Earth's rotation.

When the earth rotates, it produces geostrophic deflection forces, and when an object moves, it is also affected by geostrophic deflection forces. Water is fluid and the motion is subject to very little friction. It will rotate due to the influence of the geostrophic deflection disorientation. Left in the Northern Hemisphere and right in the Southern Hemisphere. Seek adoption.

It is caused by the rotation of the earth.

Didn't say what is the left and what is the right direction of reference?
