Chapter Eighty-Seven: The Belauf Formula
The words of the stout officer with thick eyebrows and big eyes were both a threat and a warning, and the employees of the Endeavor Factory behind Meng Jianye were suddenly psychologically abrupt, and at this time, several technicians from the acceptance team of G City also went down to the engine room, and they all shook their heads when they saw the noise-reducing shell outside the engine.
A few of them who didn't keep the door open even whispered.
"Dare to put a mask on the engine, do you still want to have a foreign affairs turmoil?"
"Alas, I didn't agree with the choice of a small shipyard in G City at the beginning, but now it's okay, I know it's unprofessional when I look at this posture. ”
"Who's to say it's not, how much of the province's economy can two 100-ton inland river cruise ships pull? In the end, a foreign affairs turmoil is all in vain. ”
"After this time, I have to write a letter to the provincial and municipal leaders to talk about this matter......
……
Similar words can be said to be endless, and the faces of the employees of the Endeavor Factory sank when they heard it, but they couldn't refute it, because they were also unsure about the upcoming reception task.
"Xiaoye, why don't you promise them first and dismantle the shell first?"
Zhen Jia, who came with Meng Jianye this time, saw this situation, and his already nervous expression became even less confident, so he came to Meng Jianye's side and whispered a suggestion.
Meng Jianye actually didn't want to make trouble, as long as the boat drove out well, and he drove back with all the tails, he would have completed the task, as for whether the two naval technical officers in front of him and the group of technicians behind him dismantled or destroyed the ship, it had nothing to do with him.
Because of this, after listening to Zhen Jia's words, he couldn't help but hesitate, but just when he was thinking about whether he would just push the boat so smoothly, the short, stout officer with thick eyebrows and big eyes was very dissatisfied with Meng Jianye's slow response, so he simply put aside the employees of Endeavor Factory and waved at the people of the G City Acceptance Team behind: "They don't do it, let's come, they dare to bear it if something happens, we can't afford it!"
As soon as these words came out, several people from the acceptance team of G City, who had long been eager to try, rushed over, and originally wondered if Meng Jianye, who was going to get off the donkey, saw this posture and stopped doing it at that time.
He was a donkey in his last life, so he can talk about it and discuss anything, but if he does it, then let's try it hard, in this life, his identity has changed, his appearance has changed, but the character of this fucking person has not changed at all.
So he rushed directly to the stout officer with an arrow step, and shouted in a low voice: "Did I let you dismantle it?"
"If you have any opinions, the leaders of the GD Military Region are also in G City, you go to sue me, but now, in order to receive the mission, you must obey my orders!" The short, stout officer with thick eyebrows and big eyes was also anxious, and his domineering momentum was directly revealed.
"What if I don't obey?" Meng Jianye didn't eat this set at the root, and the short officer with thick eyebrows and big eyes didn't talk nonsense: "Then you just stay aside!"
Saying that, he stretched out his hand to pull Meng Jianye to the side, but he didn't expect that his hand was held up by Meng Jianye as soon as he stretched out, and after moving twice, he found that he didn't do anything to Meng Jianye, so he glanced at Peng Jun next to him, and prepared the two of them to work together to add Meng Jianye, just as the two were about to start, a low shout suddenly came from outside the cabin: "Huang Jianguo, Peng Jun, what are you doing?"
As soon as these words came out, everyone looked at the cabin door, and saw a handsome middle-aged man with a comb of three or seven points, gray sideburns, gold-rimmed glasses, and an elegant temperament, standing at the door, staring at them with an angry face.
Seeing this, the people of Endeavor Factory were a little dazed, and said in their hearts where did Cheng Biting Jin come out, what did he do here?
In particular, Huang Jianguo, who was arranging with Meng Jianye, shouted loudly as if he had seen a savior: "Professor Qin, you came just in time, I was afraid that the engine would not be able to dissipate heat, so I was ready to dismantle this cover, but the people of Endeavor Factory did not cooperate, you are a ship expert, should you dismantle this cover?"
The person who came was none other than the leader of the cruise ship maintenance and support group, Qin Wen and Professor Qin, when they learned their identity, the employees of the Endeavor Factory were like frosted eggplants, one by one, there was no way, Professor Qin is not only an authoritative expert, but also the leader of the acceptance team of G City, who has ever seen their own leaders not to their own people?
Even Meng Jianye, who had a donkey's temper just now, couldn't help but be deflated, you must know that according to the instructions of his superiors, he, the technician of the construction factory, must also be led by Professor Qin, although they are all leaders, but it is a world of difference between being close and distanced, so Meng Jianye also thought about it, as long as Professor Qin is not too excessive, he will accept the organizational arrangement.
Qin Wentong obviously didn't take the focused gaze around him to heart, but walked straight to Meng Jianye, looked up and down, and then asked in a calm tone: "You are Comrade Meng Jianye of Endeavor Factory." ”
"Yes, I am Meng Jianye!"
"How did you determine your engine vents?" Before Meng Jianye could finish speaking, Professor Qin held his glasses and carefully looked at the two noise-reducing shells in front of him and the waist-thick metal pipes extending on them, and suddenly asked.
Meng Jianye's head was still thinking about how to compliment his temporary leader, but he didn't expect this idea to jump so fast, and he was a little uncomfortable all of a sudden.
Seeing that Meng Jianye's face became wonderful, Huang Jianguo and Peng Jun, two technical officers, couldn't help but snicker, people's authority is authority, a simple question can make people reveal their true form, what is called reason to go all over the world, this is it.
"What? It can't be that you guys patted your heads and came up with it, right?" At this moment, Professor Qin's elegant face also became stiff, and what he was most angry about was that kind of design and decision for no reason, which not only harmed others but also harmed himself, so seeing that Meng Jianye's face was a little ugly, Qin Wentong, who was particularly principled and a good teacher, wanted to attack.
"Using the Belauf formula, the circumference of the cross-section of the channel is multiplied by the length of the channel, divided by the cross-sectional area of the channel, and then multiplied by 1.1 times the material attraction function!"
Just when Professor Qin's face sank, and he was about to open his mouth to give Meng Jianye a lesson in ship theory, Meng Jianye suddenly said a series of strange mathematical formulas, Professor Qin's gloomy face suddenly froze when he heard this, and then a pair of thick eyebrows wrinkled together: "Don't Lauf formula? If I'm not mistaken, this formula calculates engine noise." ”
"You're right, so I'm just using him to derive, because the noise of the engine can be determined with an acoustic detector, and the sound absorption function of the material is also fixed, and the rest is just to determine the product of the circumference of the appropriate cross-section and the length of the channel, and the area of the cross-sectional section of the channel can be obtained by using the conversion formula of noise and power, and the air supply of this cross-sectional area is enough for the engine to ventilate and cool. ”
