Chapter 161 Don't you want to become a beautiful young lady?
rcf=g is the relative centrifugal force, which is the multiple of gravity acceleration.
If r and g of the motor are known, rpm can be found; conversely, if r and rpm are known, g can also be found.
For example, take the known r radius value on the r scale and the known relative centrifugal force value on the g scale. The intersection point of the extension line between these two points on the rpm scale is rpm.
If the known g value is on the right side of the g scale, the value on the right side of the rpm scale should be read, otherwise, vice versa.
g and rpm can also be converted using the following formula:
The relationship between the centrifugal force g of the motor and the rotational speed r/min:
centrifugal force (f);
Centripetal force causes an object to be attracted, repelled, or otherwise inclined toward a central point.
Centrifugal force can be explained as the tendency of an object to maintain its "limited quantity".
The difference between them is that centripetal force is in an inertial reference frame, while centrifugal force is a force in a non-inertial frame.
Formula:f=mw2r
w: Rotation angular speed (radians/second);
r: distance between the rotating body and the rotation axis (cm);
m: particle mass;
Relative centrifugal force (rcf);
rcf is the multiple of actual centrifugal force converted into gravitational acceleration;
g is the acceleration due to gravity
For the same reason, one revolution is equal to 2π radians, so the angular speed of the rotor is expressed in the number of revolutions per minute (revolutions per minute):
Centrifugation is expressed in r/min.
Separation factor calculation formula:
rcf=fcentrifugal force/fgravity=
Note: rpm should be converted into conversions/second
For example: a motor with a diameter of 1000mm and a speed of 1000 rpm.
The separation factors are:
=560
so......
g=?
When g=1500, any metal can be cut theoretically.
The centrifugal force will not change.
Of course, the premise is that the drill bit is strong enough.
From to:
The result can be obtained:
When the drill bit clamp diameter is 50mm
rpm (speed)=60000.
Liu Chi moved his hands on the keyboard at high speed. It was a very big problem to reach 60,000 rpm, especially for a motor with a diameter of only 200mm.
So Liu Chi decided to cancel the power generation device and use direct current directly.
Make magic changes again.
...
Time is like running water.
‘Ring, ring, ring…’ A burst of phone ringing interrupted Liu Chi who was doing the experiment.
"Hello?"
"Liu Chi, the thing you asked us to help with last time has come to an end." Chen Luguang's voice claiming credit came to Liu Chi's ears from the mobile phone.
"?" Liu Chi couldn't think of what happened last time.
"What?"
"What happened last time?"
"It's about your apprentice Zhou Meng. How come you forgot about it in such a short time?" Chen Luguang asked back.
"I was doing an experiment and I didn't think about it. How's it going? Is there any hope?" Liu Chi came back to his senses and asked with a worried heart.
"There is a plan over at Kongx General Hospital. After discussion/deduction, the success rate reaches 75%."
"Really, that's great. Do I need to prepare anything?" Liu Chi asked happily.
"Zhou Meng is asked to go over and check it in person to confirm whether there is any discrepancy with what is on the case list. If the error is too large, the consultation will be repeated."
"When are you going?" Liu Chi asked anxiously.
"On your own schedule."
"The sooner the better."
"You can go over when you are ready. I will give you a phone number and you can just call her." Chen Luguang said, "I have made it clear to her."
"good."
"1391235xxx, Zhang Miao is the vice president of Kongx General Hospital."
"Okay, I'll contact her later."
"Okay, if you have any questions, please feel free to contact me."
"good!"
"..." After Liu Chi hung up the phone, he thought for a while, finally stopped what he was doing and called Zhou Meng: "Girl, where are you?"
"I'm in my sister-in-law's office." Zhou Meng's clear voice came from the mobile phone.
"Save some time tomorrow and come with me to Kongx General Hospital." Liu Chi said directly.
"Why are you going to Kongx General Hospital?" Zhou Meng asked doubtfully.
"Don't you want to become a beautiful young lady?" Liu Chi said half-jokingly.
"..." After a while, Zhou Meng's trembling voice came out again: "Is it possible?"
"According to your previous case list, the success rate is 75%." Liu Chi comforted: "Don't worry, it should be fine. Brother Chi can't throw money at it. We are not short of money."
"Okay, that's it. Take advantage of the time you have today to take care of all the things you have to do these days. Although you will go check it out tomorrow, the time may not be short."
"Brother has been out recently for something and may not be back in a short time."
"Brother, where are you going?"
"For the above project, we will do some technical research. We will leave after Brother Chi has finished handling the matters at hand. It is more urgent over there."
"Uh huh huh!"
"That's it, I'll contact Kongx General Hospital first."
"..."
Liu Chi hung up Zhou Meng's phone and dialed Zhang Miao's number.
"Hello!" After the bell rang seven or eight times, a middle-aged woman's slightly old voice came into Liu Chi's ears.
"Hello, are you Academician Zhang Miaozhang from Kongx General Hospital?" Liu Chi asked.
"I'm Zhang Miao?"
"Hello, I'm Zhou Meng's brother." Liu Chi explained simply, "Just now my friend told me that the marks on her face can be cured by your hospital, and he asked me to contact you.
"
"Hello, hello, our experts have discussed Zhou Meng's case many times. Based on the case information you provided, we are still very confident that it can be cured." Zhang Miao became enthusiastic instantly.
"That's great, thank you." Liu Chi thanked him.
Isn’t it strange that there are so many people?
Anyway, no matter what happens, thank you first!
There won’t be any missing pieces of meat.
"You're welcome, the possibility of cure is very high, but because the case file you provided is not our hospital's own file, it is best for her to come to our hospital in person for a comprehensive examination to decide which method to choose.
Methods of treatment.”
"I know. My friend just told me, is it convenient tomorrow? If it is convenient, I will take Zhou Meng over for examination tomorrow." Liu Chi said a little anxiously.
"Okay, you can go directly to Kongx General Hospital. Just call me when you arrive. The address is Diaoyutai, West, Haidian District. Do you know how to get there?"
"I know, then I'll go there tomorrow morning and arrive at your place around 10 o'clock."
"Okay, no problem...you can contact me then."
"Thank you, Dean Zhang."
"..."
After Liu Chi hung up the phone and confirmed that he had nothing to explain, he continued to modify the motor.
After get off work in the afternoon, Liu Chi told Ye Yuxin about taking Zhou Meng to Kongx General Hospital tomorrow.
The next day, Liu Chi took the two of them straight to Kongx General Hospital.
Nine fifty.
Liu Chi met Vice President Zhang Miao.
She is a middle-aged woman about 1.8 meters tall, wearing white clothes, and looking rich.
"Hello, Dean Zhang, I am Liu Chi." Liu Chi shook hands with Zhang Miao with a smile on his face.
"Hello, Mr. Liu." Zhang Miao took a breath when she saw Liu Chi was so young. She glanced at the license plate and then looked at the other two cars. Which boss is this relative of?
Do you want to be so high-profile?
Aren’t you afraid that netizens will take pictures of you online and spray you to death?
But it doesn’t seem right when I think about it.
If it was a relative of a big boss, it would be impossible for the higher-ups to intervene directly, and it would also be impossible to drive a car with this license plate.
You can't drive a car like this just when you want to.
"This is my daughter-in-law Ye Yuxin, and this is Zhou Meng." Liu Chi introduced.
"Hello, Dean Zhang." Zhou Meng said obediently.
"Hello." Ye Yuxin nodded with a smile.
"You're welcome. There are a lot of people here. Let's talk in my office." Zhang Miao was not an inexperienced person. She put aside her doubts, quickly calmed down, and took the three of them back to her office.
"..."
"Mr. Liu, regarding Zhou Meng's condition, if it is not too different from the files you provided, we are very confident that it can be cured." Zhang Miao asked the three of them to sit down and poured a glass of water for each of them.
"Then I'll trouble you, Dean Zhang." Liu Chi said after taking a sip of water.
"I will now ask the attending doctor Li Yuhong to come over and ask her to take Zhou Meng for a re-examination first to determine what treatment method to use."
"Thanks."
Zhang Miao picked up the phone on the table and said a few words.
Five minutes later.
A slender female doctor, nearly 1.7 meters tall, wearing a large mask and dressed in white, walked into Zhang Miao's office.
"Dean Zhang, are you looking for me?"
"Director Li, this is Zhou Meng. Please take her for a comprehensive examination first." Zhang Miao pointed at Zhou Meng and said.
"Okay." When Li Yuhong saw the three people in front of him, a trace of surprise flashed in his eyes, and he nodded: "Your name is Zhou Meng, right."
"Yes!" Zhou Meng nodded honestly, his eyes drifting to Li Yuhong involuntarily.
"Director Li, I'm sorry to trouble you." Liu Chi stood up hurriedly and said very politely.
"It doesn't matter, a doctor has a parent's heart. It's really a little weird for such a cute little girl to have a pimple on her face. Don't worry, we will definitely find a way to cure it." Li Yuhong looked at the well-behaved Zhou Meng and squinted her eyes.
Smiled.
"Thank you, Director Li."
"I'll take Zhou Meng for a checkup first. It may take a long time, about four or five hours. If there's anything you can do first, and then pick Zhou Meng up." Li Yuhong explained.
"OK."
After Zhou Meng was taken away, Liu Chi chatted with Li Miao for a few minutes, then left, preparing to go out for a walk and come back when the time comes.
It's impossible to wait here for four/five hours.
Moreover, people are also busy with things, but they don’t have time to spend time with themselves.
...
Some office.
"Dean, regarding Zhou Meng's case, I have arranged for Director Li Yuhong to preside over the treatment and try our best to cure it," Zhang Miao said.
"Is it worth it? Using such a huge resource?" an old man next to him asked a little dissatisfied.
"Academician Chen, this matter was directly assigned by the higher-ups. In fact, not only our hospital has obtained the case files, but also USTC, Union Medical College, Yanjing Medical University...all hospitals above the top three have obtained it." Zhang Miao turned around and said,
Explained to the boss.
"What???" The old man was stunned. Zhang Miao was a little surprised. He opened his mouth and said nothing in the end.
"I don't know who Liu Chi is, but his identity is definitely extraordinary. He just came in three cars, and his car license plate number is Jingv0002x, and the other two cars are
"If I guessed correctly, it should have been fired by the bodyguard."
"..." A sound of inhalation sounded in the conference room.
"The background is hard?"
"Probably not."
"Okay, don't discuss it anymore. This is a task assigned by the superiors. We must go all out and cure the patient at all costs." At this time, Dean Wang Han, who had been silent, directly interrupted everyone's discussion.
"Dean?"
"..." Several people in the conference room turned their doubtful eyes to Wang Han.
Wang Han looked around and stared at himself one by one. It seemed that he couldn't do it without explaining clearly, so he said: "That girl is only 18 years old. She is a PhD student in computer science at Xqiao University and has just received her diploma. Moreover, her family members are all
She immigrated, but she retained her nationality."
"She's only 18?"
"You are a Ph.D. student in computer science at XQiao University at the age of 18?" The old man was a little dumbfounded: "You have graduated? Such a genius?"
"Yes, she just got her diploma and came back right away, which shows her patriotism. This alone is enough for us to try our best to cure her."
"Are you sure?"
"Sure!"
"Then I have no objection." The old man put away his previous thoughts.
Wang Han glanced at the old man and finally said: "You are not from the science and technology industry, so you don't know the influence of Liu Chi. Because of the need for confidentiality, you don't need to know it for the time being. If I want to use metaphors, his importance is higher than mine."
."
"You also heard the license plate that Dean Zhang mentioned just now. This is the security specification given above. It is his importance to the scientific and technological world, not his background."
"Understood." After hearing Zhang Han's words, there were two people who were dissatisfied, and they were instantly wiped out.
"..."
Five hours later, Liu Chi returned to Kongx General Hospital on time.
"Dean Zhang, how are you?" Liu Chi looked at Zhang Miao holding the inspection report and glanced at Zhou Meng who was happy. He had a clue in his heart and asked.
"It's not a big difference, and it's better than we imagined. The successful cure rate is very high." Zhang Miao glanced at Zhou Meng, and finally said to Liu Chi.
"Really?" Liu Chi's face flashed with joy.
"Um!"
"That's great, girl, have you seen it? Don't worry now, you can tie your hair up in the future." Liu Chi happily said to Zhou Meng.
"Uh-huh!" Zhou Meng's eyes began to mist.
"Okay, you're an adult now, do you want to cry? My sister-in-law is going to laugh at you soon." Liu Chi made up for it with a knife, causing Zhou Meng's face to turn red and make him want to hit him in embarrassment.
"Sister-in-law, look at Brother Chi bullying me again."
"I'll help you take care of him later." Ye Yuxin stroked Zhou Meng's black hair: "Take good care of him, and later my sister-in-law will take you to play."
"Thank you sister-in-law!"
"Dean Zhang, when do you think it's appropriate to start treatment? Is there anything we need to cooperate with?" Liu Chi glanced at the two women who were whispering, and finally moved his eyes to Zhang Miao.
"There is no need to prepare anything. As long as you are ready, you can start the treatment. Do you have anything to deal with? After all, the treatment time will not be short."
"..." Liu Chi turned to Zhou Meng and said, "What about you, girl? Do you have any questions?"
"No." Zhou Meng nodded.
"By the way, Dean Zhang, how long will this treatment take?"
"It depends on the subsequent recovery, but a conservative estimate is that the hospitalization time is about 15 days, and there should be about a month of recovery period after that. You need to come to the hospital for regular check-ups." Zhang Miao thought for a while and said.
"Zhou Meng, please discuss this with your parents tonight."
"Dean Zhang, what about the expenses?" Ye Yuxin, who had been silent, spoke up.
"The cost is expected to be quite high. You must be mentally prepared for this."
"?" Liu Chi turned his head and looked at Zhang Miao.
"It should be more than 500,000."
"So many?" Zhou Meng shrank his neck.
"It's okay." Ye Yuxin looked at Zhou Meng and said, "Your brother and sister-in-law are here, so you can just treat me with peace of mind."
"Um."
Liu Chi communicated with Zhang Miao for half an hour and decided to bring Zhou Meng to start treatment the day after tomorrow, leaving Zhou Meng to deal with some personal matters tomorrow.
After confirming that there was no problem, Liu Chi left with Ye Yuxin and Zhou Meng.
At night, Zhou Meng hid in bed, picked up his cell phone, and called his mother Jiang Xueyue in Europe!
"Mother!"
"Daughter, do you miss your mother?" Jiang Xueyue asked with concern: "Are you used to it in China? Have you ever been wronged?"
"No, Brother Chi and sister-in-law are very kind to me." Zhou Meng rolled over and hummed a few times.
"That's good. Last time your dad said you were living directly at Liu Chi's house. Is it convenient?" Jiang Xueyue asked.
"It's convenient, Brother Chi's parents recognize me as their daughter." Zhou Meng raised his neck and said arrogantly.
"That's good, just get used to it." Jiang Xueyue changed her subject and said, "Are you running out of money?"
"Is there any?"
"real?"
"Yeah." Zhou Meng nodded and said, "Mom, let me tell you something."
"What's up?"
"Brother Chi helped me find a relationship and said that the scar on my face can be cured. I will have it treated the day after tomorrow. Then I may not be able to call you and dad for a long time."
"Can it really be cured?" Jiang Xueyue frowned.
"Really, Brother Chi took me for a checkup today and he said that there is a high chance that it can be cured, more than 70%."
"Which hospital?"
"Empty x General Hospital." Zhou Meng said a little show off.
"Really? Does Liu Chi have any connections?"
"real."
"The cost should be very expensive, right?" Jiang Xueyue added: "As long as your face can be cured, you don't have to worry about the cost of medical treatment. Your parents will find a way."
"Brother Chi has already taken care of the medical expenses."
"How is this possible? Don't worry, my parents will find a way. Originally, I wanted to wait for another year, when my parents have earned enough money, and then let you be treated in Europe. I didn't expect that you have gone back to China now.
"
"About 500,000, don't worry, this amount of money is nothing to Brother Chi." After Zhou Meng finished speaking, he added: "Besides, I am his apprentice and sister. I will be there when I am cured."
I’m working at Brother Chi’s company.”
"Only 500,000?" Jiang Xueyue was surprised. She was stunned for a while before asking: "Really? It's only 500,000. You didn't lie to your mother."
"Well, that's what Dean Zhang said in front of Brother Chi, saying it was about 500,000." Zhou Meng said with certainty.
