Lord of Industrialization

Looking forward to, looking forward to, the news of the steam engine came.

Frederick finished his meditation, immediately changed his clothes, and headed to the Lakeside Blacksmith near Weisenberg University in a carriage with All Might.

As soon as we got off the carriage, the sound of "click, click, click" came from the lake, where many people had gathered to watch the fun.

Schmidt led a group of people to carefully observe and record the operation of the steam engine. Someone was assembling the machine next to him. After Frederick came over, the group of people immediately greeted the principal.

"How is the situation?" Frederick asked Schmidt directly after waving to them.

Now the steam engine is working, the piston is reciprocating rapidly in the cylinder, the connecting rod drives the crankshaft, and the crankshaft drives the flywheel to rotate rapidly.

All Might stepped aside and left the opportunity to the students.

Schmidt said excitedly: "Report to the principal that this machine has been running continuously for a day, and there are no major problems at the moment!"

Frederick nodded with satisfaction, and then asked: "What's the small problem?"

Schmidt scratched his head in embarrassment and said: "The main reason is that some connections in the steam path are leaking, and the accuracy of the threads and screw connections is still a bit poor."

Frederick said: "It doesn't matter. It's not your fault. Just improve slowly in the future."

There is really no one else to blame for this, it was Frederick himself who did it.

In order to reduce the size of the steam engine, he increased the boiler air pressure, which suddenly reached the level of his hometown in at least the mid-to-late 19th century. However, the processing technology and the level of workers have not kept up, so it is not surprising that some problems occurred.

Schmidt pointed to the most handsomely dressed guy in the crowd and said: "In order to solve the air leakage problem, we asked BASF to help."

BASF knew that today was Schmidt’s stage, so he kept hiding behind and pretending to be transparent.

But now that Schmidt has chosen him, he naturally appears.

"Hello principal, I see you look good, yo, you have grown taller recently."

BASF greeted Frederick with a smile as soon as he appeared.

Frederick looked this guy up and down and said with a smile: "When other people get married, their wives' belly gets bigger. Why, your belly got bigger first?"

The surrounding students all knew BASF, and they burst into laughter and were very envious at the same time.

BASF's face was full of happiness and he answered with a smile: "My wife recently bought a cookbook and her cooking skills have improved rapidly."

Then he got down to business: "I came to study the air leakage problem on the steam engine half a month ago. The main reason is that the gap is too large, and high-pressure steam can easily leak out from inside."

"I provide a kind of slime glue, which can be applied to the threads like glue and then tightened. The gaps will be filled. After solidification, it can block the steam. When it needs to be dismantled, it can be burned outside with wood first. soft."

Frederick nodded, this method was good, but he still said: "Check the glue condition more often to avoid damage after working for a long time."

BASF immediately promised to keep an eye on this place personally.

Frederick walked over to the steam engine and observed it carefully.

This steam engine is installed on a steel frame. There are four steel wheels under the steel frame. The structure is the same as that of a carriage. The wheels with hooks can rotate left and right for easy towing.

The boiler is also a little different. There is an extra shell on the outside, which is transparent from the front and back. Schmidt said it is used for heat insulation to prevent people from getting burned.

The cylinder is at the head position and installed on the side of the boiler, and the structure is quite compact.

Then Frederick discovered a new device, which was a football-thick steel pipe installed on the other side of the boiler. One end of the pipe was connected to the boiler, and the other end was connected to the high water tank.

"Is this filled with water?" asked Frederick.

"The principal is wise!" Schmidt immediately replied, "This is a water filling cylinder. You can add water when the boiler is running."

"It has magic muscles inside that can force water into the boiler."

"There is a spring check valve on the pipe to ensure that the steam in the boiler cannot come out and water can enter."

Frederick nodded. Although this was not the best solution, as the cost and weight were much higher, it was acceptable for now.

However, this is just for now, and naturally such a water injector cannot be used when it is actually produced and sold.

Frederick stood there for a long time, frowning slightly, recalling Bernoulli's equation, which he had learned when he was studying hydraulics in his previous life.

Bernoulli's equation is

p+ρv+ρgh=C

In the formula, p is the pressure at a certain point in the fluid, v is the flow rate of the fluid at that point, ρ is the density of the fluid, g is the acceleration due to gravity, h is the height of the point, and C is a constant.

In a continuous system it can be expressed as

p+ρv+ρgh=p+ρv+ρgh

In other words, the greater the flow velocity, the smaller the pressure; the smaller the flow velocity, the greater the pressure.

When water is injected, water vapor enters the water injector. Because of the high flow rate and low pressure, the water near the steam port is sucked away by it, and the water is entrained by the steam and enters the water suction nozzle.

Water and steam are mixed in the mixing nozzle behind the water suction nozzle. At this time, most of the water vapor turns into condensed water. The mixed water obtains the kinetic energy of the steam. At the same time, the diameter of this section of the pipe gradually shrinks like a bell mouth, and the water flow speed increases, and then Enter the water jet at high speed.

The diameter of the water injection nozzle is also like a bell mouth. The diameter of the pipe becomes larger and larger, the speed of the mixed water decreases, the pressure increases, and finally the check valve is pushed open and enters the boiler.

Schmidt saw the principal deep in thought, already waiting at the side with a notebook and charcoal pen.

As soon as Frederick raised his hand, two things were immediately presented.

Now he only wrote down the relationship between flow velocity and pressure. Many years later, Bernoulli's principle was renamed Wesson's fluid principle in this world.

Such a water injector has a simple structure but a complex design. When used, the pressure in the boiler must not be too high. All things considered, it is good.

Later, people tried to understand why Frederick could understand this principle at that age. The more accepted theory is that he understood the relationship between pipe diameter and flow rate from spraying water when gargling, and saw the wind lifting his skirt. After laying out the tablecloth, I understood the relationship between speed and pressure. The last article describing little Frederick’s ability to observe life and think became a must-memorize text for primary school students.

Frederick still didn't understand what was going to happen next. After drawing the schematic diagram of the water injector, he thought it was time to find graphite to make a pen. Charcoal pens were always difficult to use.

Schmidt took the notebook with both hands as if it were the most precious treasure in the world and promised to start studying it tomorrow.

Frederick's prestige among the scholars at Weissenburg University was gradually established in this way.

He continued to study the instruments next to the boiler. The pressure gauge, thermometer and water level gauge showed normal.

The water level gauge uses the same technology as the pea gun to display whether there are bullets in the barrel. It relies on the floating ball in the boiler to connect the magic circuits at different locations, and then the corresponding external crystals glow.

The most important thing is that this steam engine uses a set of control cores originally used for golem puppets, which Ogilvy calls the "Magic Brain". Through it, the boiler pressure, outlet pressure, water addition, etc. of the entire machine can be comprehensively controlled. The operation allows an ordinary farmer to control the machine by pulling the joystick after simple learning.

Because the function is simple, the price is not high.

Schmidt whispered to Frederick: "Principal, there is a special function set up in the demon brain."

Frederick asked curiously: "What function?"

"Self-destruct," Schmidt said in his lowest voice.

Frederick nodded with great satisfaction, and then said: "It is best to control it remotely."
