Chapter 456 When the sea engulfs all space

Chapter 456 When the sea engulfs all space

According to previous calculations, the initial velocity of the water flow is almost 20 m/s.

The water velocity * the cross-section S of the discharge hole is the water injection velocity.so:
S*20=2
S = 0.1 square meters

The area of ​​a window in a small room is not large, 30cm * 40cm, almost 0.12 square meters.

In other words, let AXA destroy a window completely, and the water rate is 2.4 cubic meters per second, and the time to fill the water to the ceiling will be
1200 / 2.4 = 500 seconds

Almost just enough to meet the needs?
In practice it will take longer than this.Because as the water level rises and the pressure decreases, the water injection rate will gradually decrease.But it must not exceed 600 seconds.

And the maximum speed at which the water level will rise will be 2.4 / 100 = 0.024, which is 24 millimeters per second.It will only gradually slow down after that.

For the last half meter, they should be able to climb up the passage.At this time, from when they entered the passage to the water level completely engulfed all the space, at least there is still
500 / 24 = 20.8 seconds!
In other words, they have more than 20 seconds or even 30 seconds to solve the broken overhead light, climb into the passage, and finally open the reduction cube to open the iron door.

This was unacceptably nervous for Li Huo, but it was not a problem for Meng Fei who had turned on the micro control.

"I'm in the water with you, push Ansheng out of the water first, and let him climb up first."

"Why am I the first one?"

An Sheng was listening in the room, asking in an uneasy tone.

"Because although the dome light was broken with a big hole, it still blocks the door. You need to clear all the obstacles."

Simply put, use his steel frame to clean up any glass shards that get in the way.

"Ok."

"Then An Sheng pulled me up, and finally pulled you, Director Li.

"I'll take 10 seconds to solve the Rubik's Cube. Assume the iron door will open in 5 seconds. Then we have the last 5-10 seconds to get out of the tunnel!

"Do you understand it?"

Li Huo bit the bullet and said, "Understood."

He really wants to say that this plan is completely courting death according to the understanding of normal human beings.

Let the water rush up to the point where it is many meters above your head, and then in the last closed space, in the last few seconds, play a blind turn to open the door in the darkness!
Normal people can't even hold the Rubik's Cube firmly in that situation, right?
"Mr. An, what about you, are you clear?"

An Sheng has been in manic endurance ever since he pressed his fingers against the window glass and was unable to leave.

Now those two finally discussed a way to let him get rid of this "stop leak valve" work, and he was satisfied enough.

"Very good! Let's do it!"

"I'm counting down, and when it reaches 0, you can do it and destroy that window glass."

"no problem!"

"three.

"two.

"one.

"Go!"

An Sheng activated his ability, held the tip of his teeth, and scratched a fork on the window glass.For him, the feeling is not much different from holding a knife to cut a steak.

The extremely tough PC material cannot resist cutting. The pressure of 20 kilograms brought by the water depth of [-] meters broke through the slit, pushing the broken window open like broken cardboard.

A nearly ten-meter-long water dragon roared out with the smell of sea water. The sound of water and wind roared together, like a ghost crying god!

Unfortunately, there is no light, it is dark.In the darkness, the water level rose rapidly, and the seawater flowed violently in the villa like a huge slime monster.

Even An Sheng, who had a steel and iron frame, was slapped by the turbulent water, pushed directly into the living room, and hit the wall.

His steel frame and walls of armored steel collided with a bang and a scream, but both remained unharmed.

Although the current is very strong, it will not rush to Meng Fei.Because Meng Fei had foreseen it, he stayed on the table in the living room.

The villa is like a large bathtub constantly filled with water, which soon becomes a bathhouse.When the water level covered his waist, Meng Fei obviously felt frivolous.

It's a pity that it's not warm water, which makes people feel cold from feet to head.

At this moment, he can actually swim.

Essentially, he can't swim.But when micromanagement is turned on, the world becomes a complex fluid dynamics model.

The solution of fluid mechanics is not as simple as that of rigid body mechanics.But his brain turned on the fluid simulations, coupled with precise control of his muscles, and he made effective treads and strokes.This keeps his head above the water at all times.

Li Huo has been behind him trying to grab his waist to lift him up, but unexpectedly found that this guy himself can swim well.

"You can obviously swim!"

"No, I'm an instinct inspired by the brain under crisis."

"..."
It was rare for Li Huo to talk nonsense with him, and he discovered a more serious problem.

"You seem to have forgotten one thing! It's pitch black here, and when the water level rises, we can't stay fixed on the table. How will we determine the location of the passage?"

"It's simple."

Although Meng Fei couldn't see anything, he could clearly see the structure of the entire room in his mind.

"The living room is square, with a side length of 10 meters, so the diagonal is 14.14 meters long, and half of the diagonal is about 7 meters.

"If we stay at one corner, when the ceiling is one meter above the head, keep the center line of the angle between the two walls and swim 7 meters to the middle of the house to reach the center of the room.

"Of course we may deviate in the dark, but there are three of us, as long as any one can find the correct position and shout, the others can follow the sound and swim over."

"Swim 7 meters... I'm not so accurate!"

"This is also very simple, and there is plenty of time now. You can swim around the room, and it will become clear after you get used to it a few times."

"That makes sense."

The rough water is only for the first time.When sea water filled the room almost halfway, at least the water surface on the upper level became quite quiet.

Of course, the "underwater" water flow is still injected at a flow rate of more than two tons of water per second, so it can be said that the undercurrent is turbulent.But when they stayed on the surface, it was still a peaceful pool, but they couldn't sink into it.

Both An Sheng and Li Huo took the opportunity to practice swimming in the living room.They first groped to one corner by themselves, and then swam in the dark to the opposite corner in the other direction.

Meng Fei also pretended to practice a few times and was very successful.

After the micro-manipulation is turned on, even if his eyes are invisible, he can estimate his position just by the skin's feeling of the water flow and the sound of the water waves hitting the wall during swimming.

Time passed, the water level continued to rise, and the space gradually narrowed.It's impossible to see at all, but everyone can feel the feeling of growing claustrophobia.

Meng Fei counted down the time in his mind, and he could roughly estimate the depth of the water level.

"Okay! Start now!"
