After a group of people left, Yang Qian relaxed and said with a smile, "Who is that? So stupid that you dare to drink dilute sulfuric acid?"
"I feel like ancient people were really like curious babies. They wanted to try everything and find everything novel. That thing was a battery that drove some small machines. I told them not to move, but they even secretly took a sip."
Yang Gan smiled and said, "It must be from the Mo family."
Zhang Yumeng was surprised and said, "Damn it, how did you know?"
"Nonsense, the Mo family likes weird things like this."
Zhang Yumeng shook his head and said, "Farewell to the Mo family. Shuihu just came to ask me that building a dam requires transporting stone bars and wood. Due to geographical factors, something similar to a crane is needed."
Yang Qian asked doubtfully, "This means that you can give him the whole machine, but not the one with pulleys?"
"He despises the inefficiency."
"Fuck, you bitch, you're not satisfied at all. If you hide it and don't retaliate next time, I'll let him play on his own."
Zhang Yumeng laughed and said, "Forget it. He is so old and can really build the canal. How great his contribution is."
Yang Qian did not answer directly, "Do you have any idea about the machine?"
Zhang Yumeng immediately cleared away the things on the desk, opened a neat design drawing, and pointed at it.
"This is a 55K motor designed by me. It should be able to help."
Yang Gan stood up, touched his chin, and thought, "You have made motors before, and there are many in Zhuangzi."
Zhang Yumeng rolled his eyes, "He wants something with a lot of power. I usually build 5K. Even if the table saw motor in the shipyard dies, it will only be around 11K."
Yang Gan nodded.
Zhang Yumeng was surprised and said, "So you understand too."
Suddenly, Yang Gan smiled like an aunt, "Hahahaha, what does that K mean?"
...
A drop of cold sweat fell from Zhang Yumeng's temples, and he bared his teeth and claws in an instant.
"Awesome~~~I don't understand, but I pretend to know it."
"I have almost no knowledge in these areas~~~but I know how many milliamps the power bank has."
Zhang Yumeng grinned, Yang Qian was very professional, loved history, and was proficient in cold weapons, but when it came to industries he didn't understand, he had almost no common sense.
Yang Gan took a helpless sip of wine, sat down and asked humbly.
"You can explain, I don't know much about power, electricity, etc. For example, how many kilograms of force can 55K produce?"
Zhang Yumeng stretched out a thin finger and said, "A kilowatt is a unit of power, and a kilogram is a unit of mass. They are different physical quantities and cannot be directly converted into each other. In other words, there is no way to know how many kilograms 1 kilowatt =."
"Then what are you talking about? If you don't convert it into something I can understand, how can you do it?"
"Can it be converted into equivalent units? Wait."
Zhang Yumeng took out his mobile phone and pressed it several times.
"Conversion of watts and horsepower: 1 metric horsepower = 75 kilograms of force·m/second = 735 watts."
Yang Gan looked confused, "What does this mean?"
"Oh, why are you so stupid? A horse can lift 75 kilograms of water by 1 meter per second, that is, 1 horsepower = 75 kilograms of force m/second."
"55k=74.779189 metric horsepower, which is 75 horsepower."
"5625kg·m/s(kg·/)"
"In other words, once the motor is in operation, it can lift 5.6 tons of objects at a speed of one meter per second."
Yang Qian couldn't help but open his mouth, "Fuck, fuck, you are so awesome? Can you do it?"
"It's not a big deal, the 55K motor is just a small thing. I used to buy it from Pinxixi for only ten thousand dollars, and it's not very big."
Yang Qian immediately grabbed her shoulders and said, "This thing must be produced."
"Go away."
Zhang Yumeng pushed Yang Qian and rubbed his shoulders in displeasure.
He said, "You pinched me."
"Isn't it just a 55K motor? What's the big deal?"
"Please, why didn't you make such an awesome thing earlier? As long as this thing is made."
"My warships, cargo ships in the canal, and three-bow crossbows can all be automated."
Zhang Yumeng opened her lips lightly, looked at Yang Qian blankly, and then said after a while, "Your imagination is really good, but I don't know if you can do it."
"It will definitely work. I believe you. It will be absolutely fine."
Zhang Yumeng said helplessly, "Okay, give me the data."
"The drawing force of the three-bow crossbow is between 2.5 tons and 3 tons."
"Actually, I don't know much about this, but I think this thing only costs 5K."
The corners of Yang Qian's mouth twitched fiercely, "Are you kidding me?"
"It's enough, because I'm not good at it, but after using the formula to convert it, it's no problem. The main thing is that I'm not engaged in industry. Besides, in my previous life, I could just buy any motor. Who could make it myself?"
Seeing Yang Qian's suspicious look, Zhang Yumeng suddenly became furious.
"Don't believe me? Come on, I'll write out the formula and show it to you."
Yang Qian immediately waved his hand, "Yes, yes, you are the best. Don't write it. I can't understand it even if you write it."
Yang Qian really didn't want to read it. The string of English words and unknown symbols made him blind.
"Then if you pull something from the dam, it's 55K to lift something?"
Zhang Yumeng nodded and said, "That's enough, considering that the stone bars are relatively heavy."
"What about my treasure ship?"
Zhang Yumeng let out a long sigh, "First of all, we need to know how much the boat weighs?"
"This~~~"
Yang Qian couldn't tell. After all, he had never weighed himself before. He tried his best to recall the information and said.
"Probably between 800 and 1,000 tons."
"How fast are you going?"
"Nonsense, of course you can go as fast as you can, even the speed of light."
"Haha, don't you think you are cute? I'll give you three hundred nautical miles, and you won't be afraid of the hull disintegrating.":
Suddenly, Yang Qian was stunned, and his whole body felt frightened.
"You'd better go faster if it's safe. There are thousands of roads, and safety comes first."
"You know the truth."
Zhang Yumeng quickly calculated the formula on the white paper, and it didn't take long.
With a "click" sound, he put down the charcoal pencil.
"Okay, it's not too difficult. A ship of 800 to 1,000 tons will probably cost 90K, and the craftsmanship will be much more complicated."
Yang Qian couldn't help but wonder, "Is 90K okay? This is a ship of hundreds of tons."
Zhang Yumeng glanced at him and said speechlessly, "It needs two units connected in series, with about 246 horsepower. It should be able to drive it."
"There's just another problem."
Zhang Yumeng scratched his head, feeling a little unable to keep up with Yang Qian's rhythm.
Yang Gan was obviously very happy when he got the answer. "If you have any questions, just tell me, mother-in-law. With the manpower and material resources here, I can search them."
"Do you know how much power these models of motors consume?"
Yang Qian was stunned for a moment. He really had never thought about such a problem and might have noticed something.
Yang Gan hurriedly asked, "Our battery is as big as a vaulting horse, isn't it enough?"
Zhang Yumeng sneered, "You really don't understand circuits. Isn't it written on the motor? A 5 kilowatt motor consumes 5 kilowatts per hour."
"Huh? What then?"
Zhang Yumeng's eyes widened, "What then?"
Yang Gan said blankly, "Fifty million? Don't we have five thousand watts?"
Zhang Yumeng held her head with a headache, "I'm convinced. Five kilowatts is five kilowatt-hours of electricity, and it consumes five kilowatt-hours of electricity per hour."
"Snapped!"
Yang Qian clapped his hands and said disdainfully, "Why are you so expressive?"
Damn, if you had told me earlier, wouldn’t I have known everything? How noble and noble K is, it turns out it’s just degrees. "
Zhang Yumeng almost died of anger. After taking a few deep breaths, he said.
"Our batteries are very large and heavy, but if you want me to tell you how many kilowatt-hours of electricity they contain, I don't know."
"Isn't this what you did?"
Yang Qian felt very strange. There was still an explanation for something he made that he didn’t know?
Zhang Yumeng said, "Nonsense, there is no measuring instrument, how can we measure it? Can you measure it with your hands?"
Yang Gan said helplessly, "What should I do? I'm not interested in this thing at all."
"Although the materials are different, it can be compared. A general electric car battery will probably not be used for one kilowatt hour of electricity."
Yang Gan opened his mouth and his eyes showed an expression of disbelief.
"Impossible. My previous battery car could drive more than 30 kilometers. How can I cheat on one kilowatt-hour of electricity?"
Yang Qian categorically didn’t believe it. Are you kidding me? One kilowatt hour of electricity only costs 50 cents, okay? How long can it last?
Zhang Yumeng said slowly, "Do you need me to explain it to you and make a formula?"
"Stop, stop, you win, then I'm curious how much battery it takes to fully charge the phone?"
"About 0.025 kilowatt-hours of electricity."
Yang Qian couldn't believe her ears, but Zhang Yumeng said she had a nose and eyes, and this was also her strength, so there was no reason to lie to herself.
"So, how much power do our batteries have?"
"It is estimated to be no more than thirty kilowatts, which is about thirty degrees of electricity."
Yang Qian was pleasantly surprised and said, "That's not bad."
Zhang Yumeng smiled and said, "Hey, a five-kilowatt motor can be used for six hours, a 55-kilowatt motor can't even be used for an hour, and a 90-kilowatt motor can only be used for one hour even if three are tied together. I think you are laughing. It’s a little too early.”
In an instant, Yang Qian's smile condensed.
Yang Qian calculated carefully and realized that this was wrong. It was not worth it. He hurriedly asked, "What should I do?"
Zhang Yumeng spread his hands, "I'm not a god, how do I know? It seems now that our signal transceiver consumes really low power. Of course, if the distance is far, the power consumption will go up."
Neither of them spoke, and the atmosphere became quiet. Suddenly Yang Qian seemed to have thought of something, and he became extremely excited.
"Zhang Yumeng, I know a solution that will definitely surprise you."
Zhang Yumeng raised his eyebrows and played with machines with Yang Gan. Isn't this bullying? His level is only at the level of a four-wheel drive car.
The simple transmission is already very impressive, as for the mechanical aspect.
Zhang Yumeng sneered, "I would like to experience it."
