"Everyone, I brought Charles here!"

Enrico hurriedly walked into an engineering laboratory. Several students in the room cheered after hearing the monitor's voice, but the cheers quickly subsided when Charles followed.

Someone whispered to Enrico: "We're looking for Medivh, not McGarden."

Charles wears gold-rimmed glasses today, and he dresses differently than when he was Medivh. He doesn't look the same person when he wore black-rimmed glasses in the past.

He had a good hearing and didn't care, he just smiled and said to the boy: "Your name is Pichichi, I heard Medivh say you, you have only three Mozu princess wedding dress figures for sale. "

Pichiki scratched his head a little embarrassedly, then said hello to Charles.

Charles greeted everyone warmly, and he asked Enrico: "What are you doing today? Medivh left this island to hide from the limelight. It will take a while to come back. I think I can also help."

He saw a lot of mechanical graphics drawn on the blackboard in the laboratory, as well as a lot of calculation formulas, as if designing something related to water.

Enrico said to him: "That's right, our class received a project, and Party A commissioned us to produce a machine that can pump mud and water."

"Party A's territory has a huge rotten swamp. He intends to pump the mud up to the silt fields, and at the same time transform the swamp into a lake."

Charles nodded. There are swamps of various sizes in many places in the south, and how to use them is a problem.

He asked, "Tell me how the swamp was transformed? What other specific requirements does Party A have?"

Enrique cleared his throat and introduced to Charles seriously: "The plan for transforming the swamp was designed by the Slime Frontier Corps. The first step is to flush the silt in the swamp into mud with water flow. A special spray canister is specially designed, which can flush the silt away with the water in the swamp in a short time."

Charles nodded again. Last year, after the Shield Bridge College produced the water jet, many students devoted themselves to the research on the application of the water jet.

Some students put a lot of water spray cans on a shelf that can go deep into the water, and then put this set on a boat, so a waterway dredging boat became a waterway dredging boat, and this boat can also be a guest fire boat, and the sales are good.

Ooh, the experts of the Slime Frontier Group also used this idea when they managed the swamp.

It's just that the water in the port area is flowing, and the washed out sediment will be carried away by the flowing water.

But the water flow speed in the swamp is negligible, and the mud washed out can only stop there and settle down again, so we have to find a way to get rid of it. Moreover, these muds are still rich in nutrients, and they are not bad for silting fields.

Charles said: "So, you've had problems delivering the mud, and found that the efficiency of the sprinkler can be severely degraded when used in the mud."

Piqiqi then said, "Yes, it's fine to rush thin mud in the swamp, but when you want to pump it up, it's a big problem, and you can't work hard at all."

Charles said to him: "This is impossible, because the water spray can only drive water, and the efficiency will be reduced when there are a lot of impurities in the water."

"So, we have to change our thinking. We can't just limit ourselves to the water spray cans. We have to use another method to extract the mud."

Enrico added: "We are also facing a problem. Party A hopes that the equipment for pumping mud can be used to pump water to irrigate farmland in the future."

"Our initial plan is to build a large pond on the high ground beside the swamp, and the mud and future water can be pumped in and can flow through the ditch to the silt field two kilometers away."

"So, Party A requires that the operating cost of this equipment should be low, and it should be well maintained. It is best not to use magic power."

After listening to Charles, he thought about it, the father of Party A is really busy, but it is not impossible to solve it.

It's just that everyone's thinking about the water pump is limited to the water spray can, so it will not get out of this dead end for a while.

Enrico wrapped his arms around Charles' neck and said, "You must find a way for me to see this project before I can get married."

Charles asked him, "Why, is Party A your future father-in-law?"

A boy beside him said sourly, "That piece of land belongs to Grace's family, and it is the Neytini family that is going to run that place."

Charles looked at Enrico in surprise and exclaimed: "Good guy, you pulled the fathers of both girlfriends together?"

Enrico said embarrassedly: "That... Grace's father said that when I clean up the rotten swamp, I will allow us to get married at any time. Neytini's father said that the income from operating the land is Neytini's of."

Charles reached out and tucked the guy's head under his arm, then rubbed his red hair hard.

The lover's family manages the land for his wife's family, he doesn't even dare to think about it.

After rubbing the guy's head angrily, Charles said, "I have a way, but I'm going to dinner now, and I have to go to the opera tonight..."

Enrico hurriedly grabbed Charles, who was about to leave, and shouted to Alvin, who was watching the play, "Quick, come to the lounge to get something to eat for the master!"

Charles was indeed hungry, and Alvin quickly brought a pot of tea and finger biscuits in a bamboo basket, which he immediately brought to his stomach.

"I have a way to make a machine that meets the requirements of Party A." Charles said while eating, "It's actually very simple, I will draw the principle of the core components and everyone will understand."

With his stomach padded, he drew on the blackboard.

"This is called a check valve. It is already in the glue injection machine. You may not have noticed it, but the structure of this valve is a little different." Charles pointed to the diagram and introduced, "The principle is that there is an iron plate in the pipeline, and the iron The upper left corner of the plate is the rotating shaft. When the liquid enters from the left, it knocks off the iron plate and passes through, but when the liquid enters from the right, pushes the iron plate to block the channel, and the liquid cannot pass through. The principle is clear to everyone, the details are yourself Optimize it."

Then he drew a schematic diagram.

┌┘?└-╥───┘?└┐

│???╠══════╪?

└┐?┌╨---──┐?┌┘

Charles pointed to the schematic diagram of the reciprocating pump and said: "This is a reciprocating pump. Its four ports are installed with check valves as indicated by the arrows. When the piston in the middle moves to the left, the upper left port will flow out and the lower right port will enter water, moving to the right. When the water comes out of the upper right port, the water enters the lower left port.”

"This kind of pump has a simple structure and can be matched with a variety of power sources. It is no problem to pump water and mud. Considering the large amount of debris and wear when pumping mud, I recommend using a detachable inner sleeve for easy maintenance."

"Of course, I recommend setting a filter in front of the water pump. Next, I will tell you the principle of a filter..."

"This kind of filter looks like this. There is an inclined filter screen inside. The filtered debris will be flushed into the storage room of the branch pipe next to it, and it can be cleaned regularly."

"My method is roughly like this. We discuss and discuss it, and if it feels feasible, we can optimize the design. Whether Enrico can marry a wife is up to you."

After Charles finished speaking, his stomach growled again. The biscuits just now were not very hungry, and no one stopped him from running now.

It's just that he met Professor Erbach as soon as he went out. The old principal just watched this guy introduce a bunch of things quietly outside the door.

When the headmaster saw that he was hungry, he took him to the Golden Seagull Bar outside the gate of the academy.

"It's nice to be young." Professor Erbach said with a smile, "I first took Enrico as your accessory into the academy, but I didn't expect others to be good enough to carry some responsibilities."

Charles was eating a prawn pizza when he heard a slight overtone and asked, "Principal, are you saying that I am a better person and can carry heavier burdens?"

Professor Erbach nodded and said, "It's easy to talk to smart people. I'm planning to go on a shore excursion next year. Please help me when I'm away."

"No problem." Charles nodded in agreement.

It's not surprising that the principal goes out on a public trip. Master Wolfe met Charles when he took Diana out for a walk.

They go out every few years, an important means of obtaining useful information in this age of poor information flow.

Professor Erbach asked again: "Do you have any plans to travel in the near future?"

Charles shook his head and said, "Next year is the opening year of Alice College, and I don't plan to leave."

"And after visiting the carnival these days, I have a new feeling."

Professor Erbach asked curiously, "What do you think?"

Charles sighed and said, "I found that the way humans have taken in the study of magic is somewhat wrong, emphasizing application over theory."

"I bought a lot of patents a while ago. When I was negotiating, I asked Beech to ask the inventor's ideas. As a result, many people said that they came out with trial and error on the original basis."

"This may be related to my study experience in the elves. UU reading www.uukanshu.com elves have been exploring the theoretical level and guiding the development of magic."

"So I plan to settle down and do research next year to see if the knowledge systems of the two sides can be integrated."

Having said this, he sighed in his heart. At this time, Elizabeth kept telling herself to live and grow in secret, and as a result, one big event after another made him unable to stop.

Professor Erbach nodded and praised with satisfaction. He said: "It's rare for you to have such a mind. I am very optimistic about your research. Before I leave, I will leave a letter to the professors and ask them to help you."

Charles hesitated for a moment, and finally said to the principal with a determined look: "Well, I have an idea."

"I plan to follow Queen Victoria's path to go to the Demon Race to see how they study magic."

Professor Erbach's hand shook, the wine glass fell on the table, and the golden ale spilled on the table.
