Are the whirlpools all clockwise How are the whirlpools formed Why are they all clockwise

Basically everyone knows the statement that the vortex is north and south is reversed, but I have read an article "Top Ten Scientific Misinformation in the World" that the north and south of the vortex are conditional, and the container is to be inverted in a conical shape or some regular volume, and the flow of matter is not considered. That is to say: if your container is irregular, the water flowing down does not necessarily mean that the north is going in the south.

And if your current volume is injected differently, the result will be different. If anyone is interested, they can give it a try. The north-south reversal of the vortex is the rotation of the earth, and the force is not large, and only when the above two conditions are canceled or weakened, the north-south reverse of the vortex will appear.

The northern hemisphere is clockwise, the southern hemisphere is reversed, referring to natural formation, but with the help of human beings it can become the opposite.

If it is a small container, such as a sink or bathtub, the direction of the vortex mainly depends on the direction of rotation of the liquid in the container itself, when the liquid is concentrated in the middle drainage hole, due to the conservation of rotational momentum, its direction is determined by its own direction of rotation.

If it is a large area, such as the atmosphere, etc., the formation of vortices is affected by the rotation of the earth, clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.

If the liquid itself is stationary, it is almost impossible to produce vortices, and this idea can be verified experimentally.

Remembered on a certain famous **; Top 10 misconceptions.

That depends, so it should be you. No.

It's not clockwise in the Northern Hemisphere, it's counterclockwise in the Southern Hemisphere.

Southern Hemisphere clockwise. The Northern Hemisphere is counterclockwise and is deflected towards the equator.

The whirlpools I make in the bucket can be clockwise or counterclockwise.

Yes. Because the movement of the earth is constant.

The role of the geostrophic deflection force The geostrophic code contains the causes of the rotational deflection force, and the following is an analysis of the northern hemisphere Since the angular velocity of each latitude is the same, when flying from north to south, the circle in the south is large, so the linear velocity is large, so a small linear velocity in the north is slower than the linear velocity in the south, so it deviates to the right due to inertia. It's the same with going north, from a fast place to a slow place, the speed is 'ahead', and the direction of progress is also deviated to the right. Fly along the latitude to the east and west, at this time, because the direction of gravity points to the center of the earth, and the direction of the latitude circle points to the center of the circle is not the center of the earth, you can think about it, so because of this angle, the centripetal force can not completely cancel out the centrifugal force that you rotate around the center of the circle of the parallel, so a synthesis, it will also deviate to the right.

So the vortex formed is clockwise, and if it is in the southern hemisphere, the situation is just the opposite, so the vortex is counterclockwise, and the equator is not affected by the geostrophic deflection force, because the center of the earth is exactly the center of the circle of the latitudinal circle, and the two coincide, and the gravity can cancel out the outward force. The higher the latitude, the greater the geostrophic deflection force.

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.

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, and the linear velocity of the Earth's rotation becomes smaller (the linear velocity is maximum at the equator), and the object keeps its linear velocity unchanged due to inertia, so it is biased to the east, 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.

Because the water starts to flow in different directions, the walls in the pool are tilted at different angles, and as soon as the water flows, a whirlpool will be 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.

Whirlpools are everywhere, and it can be said that where there are differences, there is the possibility of whirlpools. A vortex is a spiral confluence formed by two or more strands of energy with different directions, flow velocities, temperatures, etc., when they come into contact with each other, and are entangled with each other. The confluence forms an inlet and an exit in and out in the direction of the axis of the vortex plane.

At the inlet, the confluence is inhaled.

At the outlet, the confluence is ejected. The entrance is the equivalent of a so-called black hole; The exit is equivalent to the so-called "cosmic big **". Among the two or more strands of energy that form a vortex, the energy with fast velocity and high temperature is positive, and conversely, the energy with slow flow rate and low temperature is negative. This is actually the so-called yin-yang fish.

In the whirlpool, when viewed from the outside of the whirlpool, the inlet is negative and the outlet is positive; From the inside of the whirlpool, the entrance is positive and the exit is negative. This is why the Liangshan Zheng Yin and Yang Fish also has a pair of Yin and Yang eyes.

There are many reasons for the formation of vortices in fluids, such as viscosity, external non-conservative forces, etc., there are also many factors that affect the direction of rotation, external forces, different positions of the wall, and so on.

But there is a common type of vortex on the earth (most obvious in the atmosphere and oceans), which is produced by the Coriolis force (Coriolis force) caused by the rotation of the earth, and because of this force, the motion of the northern hemisphere of the earth will deflect to the right, and the motion on the southern hemisphere will deflect to the left, so the vortex in the northern hemisphere is counterclockwise, and the vortex in the southern hemisphere is clockwise.

However, this Coriolis force is only one reason, in fact, the flow of any fluid is very complex, external disturbances (natural wind, temperature differences, vibrations) may cause the direction of the vortex to be different, and even if the external interference disappears, the fluid may maintain the original direction of rotation due to the action of inertia, without being affected by the Coriolis force.

The effect of the geostrophic deflection force The cause of the geostrophic deflection force, the following is an analysis of the northern hemisphere Since the angular velocity of each latitude is the same, when flying from north to south, the circle in the south is large, so the linear velocity is large, so a small linear velocity in the north is slower than the linear velocity in the south, so it deviates to the right due to inertia. It's the same with going north, from a fast place to a slow place, the speed is 'ahead', and the direction of progress is also deviated to the right. Fly along the latitude to the east and west, at this time, because the direction of gravity points to the center of the earth, and the direction of the latitude circle points to the center of the circle is not the center of the earth, you can think about it, so because of this angle, the centripetal force can not completely cancel out the centrifugal force that you rotate around the center of the circle of the parallel, so a synthesis, it will also deviate to the right.

So the vortex formed is clockwise, and if it is in the southern hemisphere, it is just the opposite, so the vortex is counterclockwise, and the equator is not subject to geostrophic deflection precisely because the center of the earth is exactly the center of the circle of rotation of the latitudinal circle, and the two coincide, and gravity can cancel out the outward force. The higher the latitude, the greater the geostrophic deflection force.

Does the water vortex rotate clockwise? Why?

The water meets the low-lying places to form a spiral-shaped water vortex.

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

It should be a problem with the structure of your sink, and other people's homes may not be like this. It can't be the reason for the rotation of the earth, because relatively speaking: that force is very weak.

It is easy for the debate to show respect in the ocean. What's more, even in the ocean, the Northern Hemisphere should be counterclockwise!
