In the blazing flames, the boiler was heating, and the water in it was boiling.
And I have to say that Liu Jinghong is very divergent in thinking, and he can think of many details.
After the flames burned for three to five minutes, Liu Jinghong opened a bolt on the boiler and explained to Li Zhen:
"I think we can't know whether the water in the boiler is boiling or not, and we can't know when the internal pressure will start to build up in the boiler. So I drilled a small hole in the boiler and made a whistle shape. As long as When the bolt is opened, the small air hole is opened. If there is internal pressure in it and the internal pressure is released from the small hole, the whistle will sound. Then I can know that the cylinder has generated power."
Li Zhen glanced at Liu Jinghong appreciatively and patted him on the shoulder: "It's really beyond my expectation that you can think of this step. Next time, let's make a pressure gauge. Just look at the pressure gauge and you'll be able to I know the value of the internal pressure and the value of the power."
"Pressure gauge?" Liu Jinghong asked, and with a movement of his eyes, he understood. From the literal meaning, he already had some thoughts in his mind.
Liu Jinghong was not the only one who was smart enough to hear the words pressure gauge. Many people at Kyushu Institute of Physics were shocked and began to think deeply.
Except for the people from the Kyushu Institute of Physics, no one else could understand it.
Others did not study steam engines and did not go through this series of academic processes. Their concept of these is extremely vague.
About six minutes later, everyone suddenly closed their mouths.
"what sound?"
But I heard a hissing sound coming from the boiler. But no white smoke came out.
Liu Jinghong clapped his hands and laughed loudly: "The internal energy of the air has begun to appear."
As soon as he finished speaking, the hissing voice suddenly changed into a sharp "sentence" sound. At the same time, wisps of faint white smoke came out of it.
"Power is generated. Quick, turn off the gas lock and save steam power."
A classmate immediately inserted the bolt again, and in an instant, the sharp sound of "every sentence" disappeared.
"Is it okay?"
"As soon as the sound is heard, is it filled with energy and about to start operating?"
"Why hasn't the disk moved yet?"
“…”
The onlookers started to commotion, but the people at Kyushu Institute of Physics all had sneers on their faces.
Finally it was Qin Enze's turn to show off. He walked to the boiler and said loudly: "The mass of the disc exceeds the mass of steam power, so theoretically speaking, steam cannot push the disc to move."
As the words fell, there was a burst of commotion.
"How about playing?"
"Can't push? What's the use?"
"So you just proved that fire can heat water? Hahaha."
"Are you kidding us?"
“…”
Qin Enze laughed loudly: "So, this requires a driving force. This initial driving force is to move the disc with your hands to let the first ray of inertia appear on the disc. Under the influence of inertia, the piston is pushed to perform repeated movements. . Under the inertia and stimulating the steam force, it can keep circulating and rotating."
Everyone looked at each other and explained very professionally, but they couldn't understand.
Qin Enze walked to the Yuanpan and said, "Watch it."
As he spoke, he grabbed the edge of the disk and moved it clockwise.
As soon as he moved it, the disk immediately began to rotate slowly. Everyone at the Kyushu Institute of Physics stared at the research, especially Li Zhen, who was more nervous than anyone else.
Can it be done
When the disc rotates half a turn, the crank connecting rod connecting the center of the circle begins to expand and contract, driving the piston to begin to expand and contract.
At the critical point of half a circle, there suddenly was a small pause.
At this moment, everyone who knew the principle at Jiuzhou Institute of Physics took a breath of air, feeling that this small pause was a matter of life and death. This momentary pause seemed as long as a century.
But the next moment, the pause was no longer there. The disk continues to rotate in a clockwise direction.
But this time, it was pushed out by the piston. But it is the piston that pushes it for the second half of the rotation.
'Dong'
The hearts of everyone at Kyushu Institute of Physics beat wildly with the success of the second half of the circle.
The disk began to rotate for the third half circle, and when it reached the critical point of the fourth half circle, the pause time became shorter.
Keep spinning.
The fifth lap, the sixth lap, the seventh lap.
The speed of its rotation began to become faster and faster. After each revolution, it began to double and increase the speed of rotation.
Lap 20…
Everyone in Kyushu Institute of Physics trembled all over.
Liu Jinghong's eyes were red and he murmured: "Success...succeeded?"
"ah!"
"Success!"
"Hahahaha, it worked!"
“…”
Everyone at Kyushu Institute of Physics hugged each other, jumped to the sky and shouted, success.
The people watching all around opened their mouths in astonishment.
The disk rotates faster and faster, from being stuck in the first half circle to the rapid rotation now. The speed is extremely fast, probably reaching more than a hundred revolutions in a minute, and there is a sound of breaking through the air from the high-speed rotation nearby.
"this… "
"They succeeded!"
"They really succeeded."
"This, what scientific reason is this?"
"Why, why can he turn faster and faster just by turning it half a circle with his hand?"
"It's amazing. Is this a steam engine? What truth is it full of?"
"It really worked!"
“…”
Xu Shenxue took a deep breath and exhaled heavily, looking at the plaque of 'Jiuzhou Institute of Physics' behind Li Zhen, his heart surged.
They actually succeeded.
"Swish, swish, swish" Suddenly, the rotating disk seemed to get stuck.
Li Zhen looked at the speed of the disk's rotation and murmured: "Why does it feel like it's going to stop?"
Fang Hanxian and others had not yet noticed the strange movement of the disc, and laughed wildly: "Does this represent the era when the entire Kyushu switched from manual to steam power? Its success is enough to shake the world."
"Yes, this disc is enough to drive a carriage."
"This heralds the coming of the steam age."
At this time, Qin Enze laughed loudly and walked to Yuanpan, looking proudly at the students in front of him who looked at him enviously: "Under the leadership of Master Li, our Jiuzhou Institute of Physics can proudly announce."
Li Zhen's pupils suddenly shrank, and he saw that the plug with a small air hole on the boiler began to beat at a high frequency, as if it was struggling. And the flywheel rotating at high speed suddenly got stuck. In just an instant, it went from spinning at high speed to braking suddenly.
Li Zhen was shocked. He knew something was wrong. He knew what was wrong.
"Qin Enze, get out of the way!"
When Qin Enze was about to announce something, Li Zhen suddenly roared.
Qin Enze turned around in confusion: "Huh?"
'bang'
A loud bang resounded throughout Fuxing University, and white smoke filled the entire scene.
'Hiss, hiss' The water was poured on the flames, extinguishing the flames and emitting more intense white smoke.
The temperature of the entire site instantly rose several degrees, white smoke filled the entire site, and water vapor filled the entire space.
"ah!"
A heart-wrenching scream came.
