There is physics in life, and there are big laws in the juice machine. We know that when you put apples in the plastic tube of a juicer, the apples turn into juice after a while.

Although the juice was quite delicious, I couldn't help but wonder how the rotor could hit the apple underneath.

We know that apples are usually cut into pieces, and some apple pieces must be under the rotor. Even if you cut it very large, after a while, won't the apple pieces get smaller and reach the bottom of the rotor?

So, why did the apple chunks below turn into juice? It turned out that the water below formed an upward vortex due to the rotation of the rotor.

The specifics are that at the beginning, the vortex is downward. Due to the monolithic nature of water, when a vortex is formed under the rotor, a vortex is also formed above the rotor.

Because the rotor height is lower, the water at the bottom is subjected to more force. As a result, the vortex at the bottom is faster.

It forms a recess. The vortex at the bottom does not stop, but keeps turning. So that the recess is always there.

To fill this recess, the vortex from above creates a recess at the top. In this way, we can see the recesses on the top of the juice.

Since we talked about the rotor height, I wondered if the size of the juice particles would be affected when the rotor height became higher.

What happens if the rotor is at the midpoint of the high line? I don't think a rotor in this position can thin all the apple pieces, because the vortex at the bottom doesn't involve the bottom half of the area.

It can be assumed that the water at the bottom is subjected to more pressure than the water above. It is said that in the sea, the deeper the water, the greater the pressure.

According to this, it can be known that the water at the bottom carries excessive pressure. As a result, the lower half can form less area than the upper half.

And what doesn't form a vortex is the bottom area. Due to various forces, some of the apple particles will eventually fall into the bottom area.

Since the rotor is at the midpoint of the high line, the vortex cannot reach the bottom area. As a result, the end result is that the particles at the bottom are not finer.

Since the key to the juicer is the area underneath the vortex, the height of the rotor is very low.

This means that if Yin wants the rotor to make the apple thinner, he can't let the rotor be too high.

Where is it not too high? I'll give a rough ratio, which is 1/4 of the high line.

。 I don't know if you have thought about a question, that is, why is the rotor not full? Actually, the question is quite simple.

That is, there has to be a gap. Why? If it is full, then the rotor rotation is purely rotational.

That doesn't work at all. Only the void allows water to come in through the void. Then he was thrown out again.

The one thrown out is divided into two parts, one of which affects the water above and the other that affects the water below.

Then, the conditions are created for the generation of upper and lower vortices. However, the vortex above continues to rotate by inertia.

Once you hold a chopstick and stand in the vortex above, the vortex will slow down. This is because the formation of eddy currents is related to the rotation of the rotor.

While the rotor is still rotating, the vortex above will not stop rotating. Life is a big thing, and it's all about the details.

Sometimes we need to see them for what they are.
