According to previous calculations, the initial velocity of the water flow is almost 20 meters per second.
The water flow speed * the cross-section S of the water discharge hole is the water injection speed. 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 completely destroy a window, and the water discharge speed is 2.4 cubic meters per second, and the time it takes for the water to fill to the ceiling will be
12002.4=500 seconds
Almost just enough to meet the needs?
It will actually take longer than this. Because as the water level rises, the pressure decreases and the water injection rate will gradually decrease. But it will definitely not exceed 600 seconds.
The maximum speed of water level rise will be 2.4100=0.024, which is 24 millimeters per second. It will only gradually slow down after that.
They should be able to climb the last half meter up the passage. At this time, from the time they entered the channel until the water level completely swallowed up all the space, at least there was
50024=20.8 seconds!
In other words, they have more than 20 seconds or even 30 seconds to solve the broken ceiling light, climb into the passage, and finally open the iron door by solving the Rubik's Cube.
This was unacceptably nervous for Li Huo, but it was not a problem for Meng Fei who had turned on micro management.
"I'm in the water with you. I push Ansheng out of the water first and let him climb up first."
"Why am I the first to go?"
An Sheng asked in an uneasy tone as he listened in the room.
"Because even though a big hole has been broken into the ceiling light, it is still blocking the door. You need to clear all the obstacles."
Simply put, use his steel frame to clear out any shards of glass that get in the way.
"All right."
"Then An Sheng pulled me up, and finally pulled you up, Director Li.
"I will spend 10 seconds solving the Rubik's Cube. Assume that the iron door will open in 5 seconds. Then we have the last 5-10 seconds to leave the passage!
"Do you understand it?"
Li Huo gritted his teeth and said, "I understand."
He really wanted to say that according to normal human understanding, this plan was simply seeking death.
First, let the water surge to the point where it is many meters above your head, and then in the final closed space, in the last few seconds, play blind revolving door in the darkness!
A normal person wouldn't even be able to hold a Rubik's Cube in that situation, right?
"Mr. An, what about you, are you clear?"
Ansheng has been in a state of manic endurance since he pressed his fingers against the window glass and couldn't leave.
Now the two people finally discussed a way to get rid of this "stop valve" job, and he was satisfied enough.
"Very good! Let's do it!"
"I'll count down, and when it reaches 0, take action and destroy the window glass."
"no problem!"
"three.
"two.
"one.
"Do it!"
An Sheng activated his superpower, held the tip of his teeth, and made an X on the window glass. To him, it felt like slicing a steak with a table knife.
The extremely tough PC material cannot resist cutting. The 2,400 kilograms of pressure brought by the 20 meters of water broke through the slit and pushed open the broken window like broken cardboard.
A water dragon nearly ten meters long roared out with the fishy smell of sea water. The sound of water and wind roar mixed together, like a ghost crying!
Unfortunately there was no light, it was darkness. The water rose rapidly in the darkness, and the water flowed violently in the villa like a giant slime monster.
Even Ansheng, who was made of steel and iron, was hit by the raging water and pushed directly into the living room, hitting the wall.
His reinforced iron frame and the wall made of armored steel collided, causing a loud bang and a scream, but both remained intact.
Although the current is strong, it will not hit Meng Fei. Because Meng Fei had foreseen it, he stayed at the table in the living room.
The villa was like a large bathtub that was constantly filled with water and quickly turned into a bathhouse. When the water level reached his waist, Meng Fei obviously felt frivolous.
It's a pity that it's not lukewarm water. It makes people feel cold from their feet to their head all at once.
At this moment, he can actually swim.
Essentially, he can't swim. But when micromanipulation is turned on, the world becomes a complex fluid dynamics model.
The solution of fluid mechanics is not as simple as rigid body mechanics. But his brain turned on fluid simulation, and coupled with precise muscle control, he made efficient treading and paddling movements. This keeps his head above the water.
Li Huo had been behind him, trying to grab his waist and lift him up, but unexpectedly found that this guy was also a good swimmer.
"You obviously know how to swim!"
"No, this is the instinct inspired by my 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 won't be able to stay fixed on the table. How will we determine the location of the passage later?"
"This is simple."
Although Meng Fei could not 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 a corner, when the ceiling is still one meter above our heads, we can reach the center of the room by swimming 7 meters from the center line of the angle between the two walls to the middle of the house.
"Of course we may deviate in the dark, but there are three of us. As long as any one of us can find the right position and shout, the others can swim over by following the sound."
"Swim 7 meters... I'm not that accurate!"
"This is also very simple, and you have plenty of time now. You can swim around the room, and it will become clear after you get familiar with it a few times."
"There is some truth in that."
The water was rough only for the first time. When the seawater fills the room almost halfway, at least the upper water surface becomes quite quiet.
Of course, the water flow at the "bottom" is still injected at a flow rate of more than two tons of water per second, which can be said to be a turbulent undercurrent. But while they stayed on the water, it was still a peaceful pool, but they couldn't sink it to death.
An Sheng and Li Huo both took the opportunity to practice swimming in the living room. They first groped their way to one corner, then swam in the dark to the opposite corner in the other direction.
Meng Fei also pretended to practice several times and was very successful.
After micro-control is turned on, even if he can't see his eyes, he can estimate his position just by feeling the water flow on his skin and the sound of water waves hitting the wall during swimming.
As time goes by, the water level continues to rise, and the space becomes smaller and smaller. Although they couldn't see it at all, everyone could feel the increasingly narrow and claustrophobic feeling.
Meng Fei counted down the time in his mind and could roughly estimate the depth of the water level.
"Okay! Start now!"
