Other ideas cannot be verified due to immature conditions or lack of props.
However, the attempt of water jet technique can still be considered.
Guan Lang returned to the apartment and persuaded his cousin who was about to carry an umbrella to go to school.
It's raining so hard that if you hold an umbrella and go to class in the rain, you'll probably be soaked before you even get to school.
I sent her downstairs and hailed a taxi.
After seeing his little cousin off, he went back upstairs to inquire about the principles of industrial water jets.
He originally thought that water jets only need high enough water pressure, but after checking, he found out that garnet, emery and other abrasives were mixed into the water to assist cutting.
The principle of this high-pressure water jet cutting technology is to first let ordinary water pass through an ultra-high-pressure pump, and then pressurize the water to 400 MPa. In order to maintain the stability of the high-pressure water flow, an accumulator is required to stabilize the pressure. Finally,
Passing through a very small nozzle, with a diameter of about 100 to 100 meters, an unparalleled water arrow can be ejected at a speed of one kilometer per second.
After reading the principle, he knew that he might have thought too much.
If he wants to use Tai Chi to recreate a series of industrial water jet processes, the difficulty is obviously not something he can achieve at this stage.
The minimum accuracy cannot be satisfied. Its current accuracy is about 1mm, which is far from the required caliber.
Moreover, the conditions for creating ultra-high water pressure are not met.
Taking the surface area of a water droplet as an example of 1 square millimeter, if you want to create a pressure of one megapascal, you need to apply a force of 0.1kg in this tiny area of a square millimeter. A pressure of 400 megapascals requires about 40 kilograms of force.
His maximum Tai Chi strength is about 110 kilograms, which is quite satisfying.
But he was completely unable to evenly concentrate the force on such a small area at the same time.
The difficulty is too high, and it doesn't feel like a magical operation that he can achieve at this stage.
The area of one square millimeter is so small that the nail cap of your index finger is almost a hundred times this area.
The accuracy of his manipulation of Tai Chi force can be maintained at about one millimeter, but that does not mean that he can condense all the power into such a small range.
Although the imagination is beautiful, the reality is cruel.
The water flow of kilometers per second is really a water-cutting knife. The small white wire with three times the speed of sound can cut almost all materials at super speed, including glass, steel, stone, reinforced concrete, titanium, chromium and various composite materials. Only diamonds can be cut.
Materials with ultra-high hardness can serve as sharp edges.
He tried it in his bathroom.
First, part of the force is used to hold a ball of water in the air, and then a pipe environment is simulated to transport water. Most of the force is condensed at the end to squeeze the water droplets as much as possible to create water pressure.
It turns out that it is really impossible to realize, and it can only be used for performances at this stage.
There are several problems.
First, the pressure is not concentrated enough, and the fastest initial speed of the water droplets is only thirty or forty meters per second, which is very different from the water jet of kilometers per second.
The speed of the water droplets weakened very quickly after being ejected, and the water pressure transformed by his Tai Chi force was extremely unstable, which also caused the water flow he pressed out to be intermittent and unable to form a high-speed moving water column.
Maybe it will be possible in the future, but now it's still too reluctant given his situation.
It requires more stable control, mental strength and stronger Tai Chi power.
Guan Lang ended his exploration of new moves.
It’s not that there is nothing to gain. Perhaps when the mental power is upgraded to a higher level or the acquired internal power is purified into the innate true energy, the Tai Chi power will be revolutionaryly improved. By then, the realization of ultra-high pressure water jets will have a realistic basis.
Guan Lang has continued to take online classes as usual.
He has almost finished the advanced courses he bought.
Apart from the shortcoming of having no practical work experience, he felt that he was already qualified to teach others.
The rain outside the window is still increasing.
He walked to the bare balcony and looked at the rain layer in the sky that was so black that it looked like it could squeeze out ink.
It was clearly noon, but it seemed like it was dark night.
It's been raining for several hours, has it stopped?
Isn't this going to be waterlogged?
Guan Lang was a little worried about whether the backward drainage system in the nearby old city could hold up.
It should be the heaviest rainstorm today or even in recent years, right?
Guan Lang glanced at the ground of the community downstairs, and saw that the road had turned into a raging river.
Beverage bottles, flyers, clothes and other bits and pieces of garbage are floating on the water.
On the main road in the distance, cars were driving through the "river".
His gaze was cast into the distance, which was the direction of the yard.
It seems that his little eggplants, little tomatoes, and little Xi'an are in danger.
Such heavy rain.
Are you going to take Wu Yazhen home?
Guan Lang turned on his phone.
Wu Yazhen has already sent a WeChat message.
She told him not to worry. She had suspended classes today, but now she had to stay in the school classroom. Considering the safety of the students, the school informed the students to wait in the classroom until the rain subsided before they could leave.
However, if the parents of the students arrive at school and want to pick them up, the teacher will let the students leave. However, if you want to go home alone, you cannot.
Guan Lang asked if he wanted him to take him home.
But my little cousin doesn’t seem to have this need.
On the contrary, I feel a little at ease and contented.
Because of the weather, I can still ask questions to the teacher at any time during self-study in school, which is much more convenient.
Other students were chatting, playing on their mobile phones, or waiting for their parents to pick her up. No one came to snatch her private tutoring time.
Guan Lang thought about it and sent a reply asking him to pick him up and send him a WeChat message at any time.
It's not safe to travel with such strong ground water.
The main reason is that we don’t know what kind of garbage is mixed in the water. If the legs and feet are scratched by sharp metal fragments or glass shards, and then soaked in the turbid and dirty water, they may be infected with germs.
He has rough skin and thick flesh and is not afraid of it, but Wu Yazhen has thin skin and tender flesh which is still a bit risky.
On Douyin, various videos of rainstorms in Moments have gone viral.
Tiannan looks like it has turned into a Venetian water city.
There are also many people who use various large bathtubs as boats to shoot videos, and some people carry fishing rods and catch fish in the water on the road. It is obviously a natural disaster, but there are always people on the Internet who are making it lively.
After another two or three hours, he saw that the rain was still not letting up.
Although he did not receive Wu Yazhen's WeChat message, he thought that something was wrong with the rain and felt that it would be better to bring her back as soon as possible.
Although the school should have properly arranged the students' safety if they stay in school, it is indeed better to go home.
And there should be few safer places than staying by his side, right?
After sending a WeChat message to discuss with Wu Yazhen, he took out his rain boots and rain pants from the warehouse, and hurried out carrying his rain gear.
