Chapter 272 Water Diversion Project (4)
Xia Tian explained all the principles, and all the bamboo tubes have been connected. The next thing to do is to test the feasibility of water diversion.
The principle used here, as some viewers in the live broadcast room said before, is the siphon principle, that is, atmospheric pressure, which achieves the effect of water diversion through air pressure difference.
The most important thing to realize the siphon principle is to create an air pressure difference, that is, to make a communicating vessel.
"This is not difficult. Just make an arc with this thin bamboo and then connect them." Xia Tian took out a piece of bamboo tube that she had prepared early in the morning.
This is a hollow bamboo tube that is only half the thickness of a water pipe, about one meter long, and very flexible, making it perfect for use as a key connecting vessel.
"The next steps are up to you." She handed the pipe to Si Ye and demonstrated how to bend it. "Bend it like this, then secure it with a rope. I'll handle the rest of the connection; you just need to secure it."
Si Ye obeyed, controlling the force just right, just on the verge of breaking, and twisted the bamboo into the shape the girl wanted.
It is curved in the middle, straight at both ends, and one end is long and the other short.
There happened to be some processed ramie fibers floating in the nearby river. He used a bracket to carve grooves on the bamboo, and tied three circles forward and backward, a total of three times, and finally made a "U"-shaped connecting vessel.
While Si Ye was processing the bamboo tube, Xia Tian was making the key parts connecting the bamboo tube and the communicating vessel.
In fact, it is not a complicated object. It is just a thick tube wrapped around a thin tube. This part is used to buffer the diameter difference between the two.
In order to strengthen the fixation, she not only used fire, but also smashed it with stones. In short, she used every possible means to achieve the finished product.
In the final water filling test, no leakage was found and the sealing was verified to be passed.
After connecting the connecting tube and the water pipe, most of the water pipe laying project is completed.
"Now, how can we divert the water?" Si Ye listened to Xia Tian's words and put the connected water pipe into the water, but did not feel any water flowing in the pipe.
He wondered if he'd missed a step, but seeing the girl's accomplished look, he became puzzled. "Could it be that if we just go back and wait, will the water just flow away on its own?"
"Of course there is no water now, but we really need to go back now." Xia Tian turned around and went home.
Si Ye followed closely behind.
What's the suspense behind this? Could it be that the water diversion failed, so all the shots are cut, and they're planning on using special effects?
[The previous one is so uneducated! There was air in the water when you put the connecting tube into the water. You have to pump out the air from the other end of the pipe!]
[This is a common principle. It's not soil cultivation, so it can be done even without special effects.]
[That's right, if you're interested, you can try it out at home! Once again, I admire Xia Xia for being so smart!!!]
Xia Tian returned to the cave along the laid pipeline.
As the barrage said, now we have to proceed to the most critical step of water diversion - emptying the air in the pipe.
At present, the water pipe has been sealed as a whole. In order to create an air pressure difference with atmospheric pressure, the air inside must be pumped out to create a vacuum state inside.
In this way, the pressure in the communicating vessel on the other side is unbalanced, and the river water can be pressed here by atmospheric pressure, thus achieving the purpose of water diversion.
