A rain, at the end of May, washed away the green leaves in the mountains and forests, and the birds flapped their wings and flew high into the sky in the fresh air.
Under that rainbow, the one-ton boiler temporarily escaped the shackles of gravity with a loud bang.
With a loud "bang", the boiler flew over the hill for more than 200 meters and landed in a mountain stream. The rabbits who were drinking water in the distance were startled and fled in all directions.
On the hilltop one kilometer away, a group of soldiers divided into two groups, one going to the place where the boiler was first fired, and the other to the place where the boiler was dropped.
Frederick frowned and was speechless towards these guys.
He just mentioned that he was worried that the boiler would explode due to excessive pressure, and then the group started destructive tests. Ogilvy also made several special pressure gauges.
These pressure gauges are connected to the boiler through long pipes. The pointer on the dial moves with the pressure, and at the same time, a toothpick drives the pointer on the opposite dial.
When the pressure of the boiler disappears or the boiler and the pressure gauge are blown up together, the pointer on the second dial can stay at the position of the maximum pressure of the boiler.
The fifth boiler is being blown up now, and it is planned to blow up 5 more boilers to obtain enough data.
The boiler fried this time is a finished product after design and positioning. The design length is 2.5m, the outer diameter is 1.2m, and the wall thickness is 12mm. It uses slightly strengthened elemental steel and weighs about 1.1 tons. After adding an appropriate amount of water, it weighs about 3.3 tons.
.
Today, the boiler only needs to be installed with instruments, heating magic array and control system to be used, but the air outlet and safety valve are blocked.
"My heart is bleeding." Frederick sighed and said, "These are all gold coins!"
All Might on the side smiled. After all, the money he spent was not his own, so he smiled quite happily.
Frederick continued: "Well, in the future, a steam engine will cost nearly a thousand florins. Who can afford it?"
Ogilvy and others estimated the cost of the steam engine, and the price scared Frederick.
This means that nobles below the baron level cannot expect to buy steam engines.
"It doesn't matter." All Might is knowledgeable, "Others can't afford it, so why can't our Lord Paladin afford it?"
"Your large glass plate is so flat and smooth that even the king sent someone to buy it."
Frederick curled his lips, made a cheap "Holy Scripture" himself, and donated the formula of maltose. The Church of Light gave him the title of Holy Knight and an enchanted saber, and then nothing happened. Seeing his expression, All Might asked curiously: "Are you dissatisfied with the Church of Light?"
Frederick did not deny it.
A strange smile appeared on All Might's face.
"What's wrong?" Frederick was a little surprised to see him smiling like this, "Is there something I don't know about?"
Ogilvy smiled and replied: "You will know when you grow up."
Then he changed the subject: "The church is quite rich. What do you think about letting them buy the tractors you mentioned and rent them to farmers?"
"Not very good." Frederick shook his head, "Nowadays, there are still many farms with a field system. The tractor plows the land of two families at once, and the field ridges in the middle are gone. How to calculate it?"
"Landowners may rent it. Their common land is a large area and it is quite convenient to use."
"If we really want to promote tractors, the land must be redistributed between landlords and tenant farmers, at least so that the land becomes one piece like in my territory."
"When we arrive, the fields in a village may only have four or five plots divided according to crop rotation."
"Others can't afford a steam engine, so we can use it internally."
"How long do you estimate it will take to complete all the work after the boiler experiment is successful?"
Ogilvy made a mental calculation and said, "It will take another month to generate the first machine."
"If we want to mass-produce it, I think it will be next year."
Frederick thought for a while and asked: "Is the current steel production enough?"
Ogilvy is now equivalent to the director of the Industrial Bureau of Weisenland and is very familiar with this matter. He replied: "The smelter will be able to officially start production next month. Enough raw materials and fuel have been reserved. Skilled workers are already in place. Apprentices
Workers learn while working."
"The construction workers building the smelting plant are now moving to Langnar City in the south to build a cement plant there according to your plan."
Frederick nodded slightly and then said: "At present, steam engines are of great use in machine production. Now we can start planning to replace other power sources. In the future, the obsolete magic reciprocators can be sold to the village."<
/p>
Ogilvy was a little depressed, thinking that his magic reciprocator could make more money, but he didn't expect that a more powerful steam engine would appear.
He replied: "The replacement of the two machines is not a big problem. They are essentially reciprocating motions, and there are very few things that need to be changed."
Frederick suddenly said: "The steam engine is ready, we should start to enter the textile industry."
"You arrange for people to find the best weavers in the territory. In the autumn, we will discuss how to use steam engines for spinning and weaving."
All Might immediately agreed.
Frederick took a deep breath of the fresh air on the top of the mountain to relax a little.
As the stalls spread out, more and more things happened.
He had previously told the Grand Duke of Mainz about the Edelweiss Library, and the Grand Duke took the initiative to find a master architect who was now studying the layout of the Pentagon.
The first phase of the army's recruitment has ended, and now the new recruits are undergoing physical training and traditional pike formation training. He hasn't had to go and see it yet.
Wait.
Frederick and Omet chatted about things in the territory for a while, and the student team led by Schmidt came over to report after sorting out today's experimental data.
"Principal, Professor Ogilvy," Schmidt said, holding a piece of paper, "the results are out."
Ogilvy was quite satisfied with Schmidt. When he saw someone making money, he didn't ask the principal for advice. Instead, he looked for work on his own. He was discovered by the principal at a paper mill, and finally got a knighthood by using a double-sided printing machine.
As promised, the work of the steam engine was handed over to him.

After Frederick nodded, Schmidt looked at the data on the paper and said: "When the boiler exploded today, the internal pressure reached about 25 atmospheres. Judging from the status of the boiler and the scene, it was the screws on the top plate that could not withstand the pressure and collapsed.
."
"The explosion was so powerful that the surrounding wooden piles were blown away, chickens and ducks were killed, and the flying roof broke a fox and a tree."
Frederick nodded and said thoughtfully: "The normal working pressure of this boiler is 12 atmospheres, and the maximum pressure is 15 atmospheres. The safety margin of 10 atmospheres is enough."
"Remember to take the boiler back and melt it again. I don't have that much money to make new materials."
Schmidt had a bright smile on his face, as long as he didn't have to pay for it.
Frederick glared at him fiercely, and then asked: "How is the steam engine doing?"
Schmidt's face suddenly darkened, and he said cautiously: "There is still a gap between the sealing ring on the cylinder and the piston. During the water filling test, it was found that water would seep in."
Frederick thought there was nothing he could do about it, so he said: "Let it leak, just control it within the tolerable range."
"Solve the existing problems first, then solve them, okay?"
Schmidt breathed a sigh of relief and said: "Principal, I have two ideas."
"Can a safety valve be controlled by a spring? If it is the current one, it will be fine if it is flat. If it is tilted, its working pressure will be reduced."
"The second is the accessories on the boiler. Can their safety strength be set between the working pressure of the safety valve and the boiler's ultimate pressure, acting as a second safety valve and also an early warning before explosion?"
Frederick thought for a while and said: "You can take care of these by yourself. The next step is up to you. I am very optimistic about you."
There is only so much he can take out. The rest is for these scholars to continue to study and develop through research.
Schmidt immediately shouted happily: "Thank you principal for your cultivation!"
