The Troublesome Hero Among the Heroes

At ten thirty in the evening, the bell rang throughout the laboratory building.

The janitor who was ringing the bell walked to the top floor, and found that the place was still brightly lit, and there was a lot of people, and a group of students and professors did not intend to rest.

In the afternoon, Principal showed up. Charles arrested him to mobilize everyone. The students who were arrested later became energetic.

Charles took a small notebook and shuttled through the laboratories of each team, recording the progress of today's research, as well as tomorrow's plans and areas that need help and coordination.

He doesn't want everyone to stay up late. Practice has proved that a good rest can improve the efficiency of scientific research.

After recording the situation of a group, he drove everyone to the restaurant for supper, then went back to bed, and came over for breakfast at 7:30 tomorrow morning before continuing.

Finally, I came to the laboratory where the water spray canister was studied. At lunch, he was full of confidence and declared that he would soon solve the ring magic array problem. Nick Collins, the handsome boy, was standing in front of the blackboard, holding A pointer explains to the students what needs to be modified in the magic array.

Charles didn't bother them, and stood by and listened quietly.

I have to say that the level of this Collins classmate is still quite good. In less than a day, he distinguished the energy distribution and transmission system of the ring magic array and the work system. And prepare to start to modify the part of the magic array that works on the wind to work on the water.

Be aware that the ring magic array is produced by the demon race, which is different from the human magic array. It is necessary to analyze the meaning of each part of it is not simple.

As for the strength effect, theoretically speaking, as long as the work part is replaced, the hair dryer can become a water jet.

Actually, Charles just looked at everyone with a smile of encouragement. There are some problems that you won’t realize if you don’t miss it once.

Collins's explanation is over. He has seen Charles watching from the side, but the expression is a bit unpleasant.

The expression reminded him of the grandfather who passed away. Grandfather smiled like this when he watched the magic array he invented, and then ruthlessly singled out a lot of mistakes.

He asked: "Student Medivh, do you have any insights on this magic array?"

Charles still smiled like a great grandfather, and said, "I think you said That’s right, it’s getting late, everyone eat something and go back to sleep, at worst, let’s ask Professor Babbage to pull the boat."

Then come and help the glasses brother solve the structural calculation problem. At this time, Professor Babbage, who was passing by the door, grabbed the guy with the claws of a giant dragon and threw it out of the window.

The roof of this laboratory building is a great place to peep into the girl’s bathroom. When a certain yin was thrown out, he moved towards the bathroom and flew towards...

Fortunately, you are someone In order to escape, I have practiced wind wing, otherwise I would fly into the bathroom from the ventilation window on the top of the wall.

Charles who escaped a disaster did not dare to go back, so he went straight back to the gym and went back to the dormitory to take a bath and sleep after finishing tonight's exercise.

Tarantula, who lived here before, has moved out. The magazine publisher Chamber of Commerce has taken several warehouses as a printing plant. She and the people from the magazine rented a house in the vicinity. When it comes to housing and office, the landlord is Old Brother who is familiar with Charles fishing.

Vichy got Tarantula a pass for an Academy cleaner, allowing her to enter and exit the Academy freely and come back to live here.

However, the first issue of the Chamber of Commerce magazine is ready to be published. She is now staying at the printing factory every day and will not be back for a short time.

After completing today’s exercise and taking a shower, Charles decided to walk back to the boys’ dormitory tonight. The wind was quite cool tonight, and the night sky was brilliant.

In a little while, the island will be shrouded in fog in the autumn night, and you will not be able to see the stars in the sky at night.

Passing by the laboratory building, there is a room on the top floor with a light on.

Charles flew to the window sill and saw a man holding a cup of tea, looking intently at the circular magic array on the blackboard.

"Did you find a problem?" he asked.

Collins did not turn his head and replied: "I always feel that something is wrong. My intuition tells me that the water outlet speed may not meet the requirements, but I didn't find the wrong place."

Charles just now I noticed the problem in the magic array. This is indeed a small problem that hits newcomers, so I used magehand, picked up a piece of chalk, and wrote a formula in the empty space of the blackboard:

Eₖ=½mv²

This world also teaches the kinetic energy theorem, but it is mostly used in the research of crossbows and catapults, and is rarely used in the research of magic arrays.

In the past, magic arrays emitted formed magic elements, not matter in the traditional sense. The relationship between magic power and element movement speed was calculated by another formula.

Except for several ice attributes and earth-rock magic, the kinetic energy of magic elements is not important, so few people think about it.

And this ring-shaped magic array with blowing and spraying water is different from the previous magic array. It relies on the work of the elements to drive the medium of wind or water, so the scope to be considered is not the same as the previous magic array. Same.

For example, the magic array of the hair dryer is to kick out an ordinary football, while the water spray is to kick out a football filled with water.

Go down with the same strength and the football filled with air flies fast and far, but the football filled with water will naturally not fly so much. In more cases, it will roll on the ground for a certain distance.

What Collins just said was just replacing the part of the magic array that works on air with work on water, but the distribution and output system of magic power has not changed. This is like just filling a football with water. But the strength of that kicking leg hasn't changed at all.

This problem was encountered in Lilika Bishop that year. The researcher joked that he thought that the water spray tube could "spray three meters against the wind", but it turned out that even the "downwind wet upper" could not be achieved.

"so that's how it is!" Collins quickly understood the meaning of the kinetic energy formula on the blackboard, "If the magic power output in the magic array does not change, it will be When doing work, the speed of water will become very slow, right?"

After he finished speaking, he wrote a formula on the blackboard and calculated that under the same magic power energy , The velocity of air with a density of approximately 1.3kgm³ at the outlet is v₁, then the velocity of water v₂=0.036v₁ㅤ.

"Theoretically, the magic power output must be increased by almost 28 times to make the water flow reach the speed of the wind, isn't it?" He turned his head and looked towards the window, but there was no one, Charles is writing After finishing the formula, I slipped away.

In the eyes of someone you, his thinking is correct. Even if no negligence is found now, the model will be made tomorrow for testing, and it will be analyzed due to the lack of water spray from the spray canister.

But now that Collins is vaguely aware of this problem, Yun X doesn't mind turning into a great grandfather and pushing the youngster forward to save him from detours.
