"The hero who troubles the heroes (

At half past ten in the evening, the bell rang all over the laboratory building.

The janitor who was ringing the bell walked to the top floor and found that the lights were still bright and the voices were full of people. A group of students and professors had no intention of resting.

When the principal appeared in the afternoon, Charles arrested him to mobilize everyone, and the students who were arrested later became very motivated.

Charles took a small notebook to shuttle in the laboratories of each team, recording today's research progress, 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 would rush everyone to the restaurant for a late-night snack, then go back to sleep, and come over for breakfast at 7:30 tomorrow morning before continuing.

Finally, I came to the laboratory where the water spray cans were researched. At lunch, the handsome boy Nick Collins, who confidently claimed that he could solve the problem of the circular magic circle soon, was standing in front of the blackboard, holding a pointer to explain to the classmates. The places in the magic circle that need to be modified.

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

I have to say that the level of this classmate Collins is still very good. In less than a day, the energy distribution of the ring magic circle, the transmission system and the work system are distinguished, and he is ready to start working on the wind. That part of the magic circle is modified to work on water.

You must know that the circular magic circle is produced by the demons. It is different from the style of the human magic circle. It is not easy to analyze the meaning of each of them.

As for the strength effect, theoretically speaking, as long as the work part is replaced, the hair dryer can be turned into a water spray.

In fact, Charles just looked at everyone with an encouraging smile, and there are some questions that you won't appreciate without missing a beat.

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

That expression reminded him of his grandfather who passed away. Back then, his grandfather smiled as he watched him talk about the magic circle he invented, and then mercilessly picked out a lot of mistakes.

He asked, "Student Medivh, do you have any insights into this magic circle?"

Charles still smiled like a grandfather and said, "I think what you said is right. It's getting late now. Let's go back to sleep after having something to eat. Let's let Professor Babbage pull the boat."

Then he came over to help Brother Glasses solve the structural calculation problem. At this time, Professor Babbage, who happened to pass 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 perfect place to peep at the girls' bathroom. When a certain yin was thrown out, it flew straight towards the bathroom...

Fortunately, a certain person had practiced wind wing art to escape, or else he would have flown into the bathroom through the ventilation window on the top of the wall.

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

Tarantula, who had lived here before, has moved out. The magazine publisher will take over several warehouses to use as a printing factory. She and the people from the magazine rent a house and office nearby. The landlord is the same as Charles. The old fisherman.

Vichy got Tarantula an academy cleaner's pass, allowing her to enter and leave the academy freely and come back to live here.

However, the first issue of the Publishers Association's magazine is about to be released. She is now at the printing house every day, and she will not be back in a short time.

After finishing today's exercise and taking a shower, Charles decided to walk back to the boys' dormitory tonight. The wind is cool tonight and the stars are shining brightly in the night sky.

Before long, the island will be shrouded in fog on autumn nights, making it impossible to see the stars in the sky at night.

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

Charles flew to the windowsill and saw a man holding a cup of tea, staring intently at the circular magic circle on the blackboard.

"Found a problem?" he asked.

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

Charles noticed the problem in the magic circle just now. This is indeed a small problem that hits newcomers, so he used the hand of a mage, picked up a piece of chalk in the air, and wrote a formula on the empty space of the blackboard:

E?=?mv2

The kinetic energy theorem is also taught in this world, but it is mostly used in the research of bows and catapults, and is rarely used in the research of magic circles.

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

With the exception of a few ice-based and earth-rock magics, the kinetic energy of the magic element is not important, so few people think about it.

And this circular magic circle that blows wind and sprays water is different from the previous magic circles. It relies on elements to do work to drive the medium of wind or water, so the scope to be considered is different from the previous magic circles.

For example, ~lightnovelpub.net~ The magic circle of the hair dryer is to kick out an ordinary football, while the water jet needs to kick out a football filled with water.

If you step down with the same force, the football full of air will fly fast and far, while the football filled with water will naturally not fly that much, and more often it will roll on the ground for a certain distance.

What Collins said just now is to replace the part of the magic circle that works on air with water, but the distribution and output system of magic power has not changed. It hasn't changed at all.

Bishop Lurica encountered this problem in the past. The researcher joked that he thought that the water spray can "spray three meters against the wind", but it turned out that he couldn't even "wet the upper in the wind".

"So it is!" Collins quickly understood the meaning of the kinetic energy formula on the blackboard, "If the magic output in the magic circle remains unchanged, then when work is done on water whose mass is much larger than air, the speed of water movement will become Very slow, right?"

After he finished speaking, he wrote a formula on the blackboard, and calculated that under the theoretical conditions, under the same magic energy, the speed of air with a density of about 1.3kgm3 at the outlet is v?, then the speed of water v?=0.036v ??.

"Theoretically, the magic power output has to be increased almost 28 times to make the water flow to the speed of the wind, isn't it?" He turned his head to look at the window, but there was no one. Charles slipped away after writing the formula.

In the eyes of a certain person, his thinking is correct. Even if there is no negligence found now, after making a model for testing tomorrow, it will be analyzed because of the lack of water spray from the sprinkler.

However, since Collins was vaguely aware of this problem, Yi would not mind turning into an old grandfather and pushing the young man forward, so that he could avoid detours.
