Chapter 452 Hardcore Solving
"Li Ju, your ability is forbidden, right? As long as you forbid him to use the ability first!"

Thousands of years ago, Li Shibai possessed two abilities.But now Li Huo has only one ability registered, and that is "forbidden".

Meng Fei suspected that these abilities, like his system skills, were continuously upgraded and increased.It's like one bug triggers another.It's just that Li Huo didn't understand it for the time being.

"good idea!"

When Li Huo expressed his opinion, An Sheng's mouth was covered in blood and flesh, he muttered and couldn't speak, with a look of despair on his face.

"It is forbidden to use the ability to strengthen the physical body!"

When An Sheng's teeth were pulled out together with red blood and nerve fibers, Meng Fei couldn't "repair" him immediately.

Because his "restoration" is a process similar to going back in time by using negative entropy.If "restored," it causes the extracted tooth to return to its original position.

Fortunately, An Sheng is the executioner, and his body already has a certain recovery ability, but it is slower than Meng Fei's "repair".
"Use your abilities, pinch this tooth with your fingers, and rub it here, just like drilling a hole. The area should not be too large."

To be on the safe side, Meng Fei decided to start from a small scale.

"Bah! No...problem!"

An Sheng spat out the blood from his mouth.

His answer was a little vague.After all, his lips were swollen like a sausage just now, but now they are visibly shrinking and recovering.

The An family's "reinforced iron frame" started up again, and Meng Fei felt as if there were many invisible forces in the void squeezing An Sheng as the center.

Under the squeeze, his two fingers became like iron pliers, clamping the tooth, like an indestructible hardware processing robot.

The tips of his teeth quickly scratched the surface of the PC glass, which was many times stronger than Li Huo's operation, as if digging out jelly with an ear pick.

The PC glass is visibly pierced by the naked eye.

But they failed to penetrate the void beyond the game plane, or smell the fresh air outside.Instead, a very thin stream of water spurted out!

"I'll wipe it! It's actually water outside!"

An Sheng had sharp eyes and quick hands, and decisively blocked the leak with his fingers.

"To be precise, it's sea water."

Li Huo dipped his finger on the back of An Sheng's wet hand and smelled it. He could smell the salty smell of the ocean.

"No wonder why it's so dark outside, because it's at the bottom of the sea!"

An Sheng felt that his heart was swallowed by the deep black seabed.

If the outside is the bottom of the sea, how is it possible to escape?Wouldn't opening the windows mean drowning in sea water?

"The sea outside is not necessarily the bottom of the sea. Although it is very dark, even if it is a shallow sea, if it is really after eight o'clock in the evening outside, then the water will be very dark."

Li Huo said.

"You mean we just smash the cans, tear down the window and swim out? What if it's deep outside? We don't have oxygen cylinders."

This is unarmed diving, direct diving without any equipment, the highest record in human history is 113 meters.

But this is the pros.As ordinary people, they recommend that unarmed diving should not exceed a depth of 10 meters.Otherwise, it is easy to turn into courting death with bare hands.

The executioner, An Sheng, was physically strong and resilient, but no matter how he recovered, he couldn't change the oxygen.The lack of oxygen in the brain will cause him to fall into a coma, and the ability will also burp.The same goes for Meng Fei.

"So, while we're in the ocean, it's not necessarily the deep ocean. What we're trying to determine now is the depth of the ocean we're in."

Li Huo continued to publish very scientific opinions.

"If the depth is less than 5 meters, maybe we can escape through the window. If the depth is greater than 10 meters, in such a dark situation that we can't even figure out the direction of the sea surface, we have to reconsider."

"It's dark outside now, how do you know how deep we are here?"

An Sheng asked.

"This can be calculated."

Li Huo thought for a while and said.

"There is a certain relationship between water pressure and depth. As long as we know the water pressure, we can deduce the depth we are in."

"I've figured it out."

Meng Fei followed Li Huo's words.

He lay down on the ground and noticed the position of the water marks, and turned on the micro-management.After the micro-manipulation is turned on, he can accurately judge the position of the object, and the calculation becomes extremely fast.

In less than a second, he had calculated everything he wanted.But it would be boring if he didn't slow down to tell the actual process.

Except for Ai Ting and Suzaku, no one knew about his micromanipulation ability.So he still had to pretend to do some calculations and give a brief description to the two people present.

As for whether they could understand it, that was none of his business.

This jet of water is so powerful that it shoots directly into the living room from the small room. Based on his "micro-manipulation" gaze, the farthest reaches the floor 6 meters away.

This is the known condition.Now the solution target is the depth of the water level where the small hole is located.

According to the calculation formula of liquid pressure, the pressure F that the small hole can generate is the pressure * cross-sectional area of ​​the small hole.Assume that the cross section is S, and the water pressure at the water depth H is the density of water 1000*gravity acceleration g*water depth H.so:
F = 1000 * gHS, obtaining equation (1).

Let the length of the small hole be dL, then the volume of water in the small hole is dL*S.And it is known that the density of water is 1000, then the mass m of water in the small hole is:
m = 1000*dL*S.

According to the law of kinetic energy, the water in the small hole accelerates the distance of dL under the action of pressure F, and the kinetic energy obtained will be one-half times the mass times the square of the velocity v, and the equation is as follows:

F*dL =(1/2)*m*(v^2).

m has been determined to be 1000 * dL * S, so the equation is:

F*dL =(1/2)*1000*dL*S*(v^2), obtaining equation (2).

Substituting equation (1) into equation (2) yields:

1000 * gHS * dL =(1/2)* 1000 * S *dL*(v^2)
Eliminate the 1000* S * dL that exists on both sides, and finally get:
v^2 = 2gH
In other words, the height H is directly related to the initial velocity of the ejected water.If the velocity v of the water flowing out of the small hole is known, the depth of the water level where the small hole is located can be directly calculated:
H =(v^2)/(2g)
Among them, g is the acceleration of gravity 9.8, so the only unknown quantity that needs to be calculated is the initial velocity of water flow v!

The speed of the water flow is horizontal, and it hits the ground after shooting 6 meters away.Roughly estimate the loss of 30% of the air resistance distance, no resistance can shoot 9 meters away.

How long did it take for the distance of 9 meters?Time is the time it takes for a drop of water to fall from a small hole to the floor. This is a free fall motion. How to solve it?

In free fall, the height h is equal to one-half the acceleration due to gravity g times the square of the time t.so:
h =(1/2)*g*(t^2)
It is known that h is the vertical height between the small hole and the floor. After Meng Fei's "micro-manipulation" visual measurement, it is about 1 meter, and the acceleration of gravity is 9.8, so the time t is:
(t^2) = 1 * 2/9.8
t is about the square root of 0.2, which is about 0.45 seconds.

The horizontal velocity v of the water flow is shot 0.45 meters away in 9 seconds, so this velocity can also be calculated very simply!
