Chapter 369: What is the normal lung capacity of a dwarf?
The steam engine puffs and puffs of steam.
The generator rotor spun.
The electrolyzer was bubbling, oxygen was blowing out silently from the iron pipe, and white fire was rolling beside the magma pool.
Jinna ran from the steam engine at one end to the oxygen tube at the other end. Gavin kept his mouth shut and held the frame, not daring to move. Feilai and Prince Rosegar sat on the ground with their feet pressed against the front, pulling on the bellows with all their strength. Hanna
He rolled up his sleeves, muscles on his arms flexed, and stared at the ore smelted in the white fire.
With oxygen continuously blown into the furnace, the flame is raised to an extremely high temperature, and the ore smelting is particularly smooth. The ore and charcoal are stacked layer by layer, igniting a fierce flame in the furnace. The furnace is filled with orange and red, and only the most experienced eyes can see it.
Through the fierce flames, I saw the ore turn red, soften, and turn into pig iron...
Everyone was extremely busy. Only Gretel, who even donated the generator and oxygen-making equipment, couldn't water the rabbit. He moved closer to the furnace, but he was afraid of heat and ashes, so he had to water himself.
I got a [cold-resistant and heat-resistant] patch, squatted aside and looked at the strings of bubbles in the electrolyzer.
"Crack."
There was a sudden soft sound. It was almost invisible amidst the roar of the steam engine and the whirring of the bellows. But Grete jumped up all of a sudden:
The electrolyzer is no longer bubbling!
out of battery?
Where is it broken? Did the fuse trip? No, there is no fuse in this broken circuit, so it doesn’t matter if it tripped. Is the mercury arc rectifier broken? God bless, but don’t do it!
He stood far away and used his mage's hand to open the wooden box containing the rectifier and carefully looked at it. The box was dark, with no blue sparks dancing or making any tingling noises. Then he threw himself in front of the generator.
At first glance, I noticed that it smelled...
"Stop!" he yelled:
"The motor is burned out!"
"The white fire is gone!"
Hanna also shouted at the same time. Suddenly, all eyes were fixed on Gretel. Gretel scratched his hair:
"Uh... Well, the steam engine is too big and the generator is too small. Let's make a bigger one..."
“How big will it be?”
"I don't know... Anyway, the magnet should be made larger, and the coil should be wound a few more times?"
The output power of the generator is related to the size of the magnet (should be the magnetic field strength), the number of turns of the coil, and the diameter of the wire. How to relate it specifically, how many turns to make, and what size of magnet can match this machine
Steam engine?
Grete said, I'm sorry. When he was in high school, he only learned that electric wires can produce electric current by cutting magnetic fields. Then, goodbye.
Finally, he still had basic common sense: if the coil was burned, the steam engine must be too powerful and the generator too small. Just make a bigger one. Since there was no one else on site who knew how to generate electricity, Grete bit the bullet and took charge.
Command tasks:
Find copper wire!
Insulate the copper wire!
Find a larger magnet and cut it into a rectangular shape! What? Magnetic field strength? Hang an iron in the middle, let the two magnets face each other across the iron block, and see which way the iron block swings and that's it!
Build the frame, fix the magnets, rewind the wires...
Gretel moved her mouth, Jinna took action, and a group of men started to do it. The ready-made generator was stuck there, and they made a bigger one. In the eyes of the dwarves, well, it was just a half-day effort.
Moreover, because Grete couldn't tell how big it should be, after one set of generators was finished, Jinna used the remaining materials to make a slightly smaller one. She set it up, reconnected the wires, and started working!
In the furnace, the blazing white fire burst into flames again.
Gretel touched here and there to make sure that the coil was not heating up and that the electrolyzer was running normally and that he did not need to think of maintenance. Then he returned to the corner and continued to watch the rabbit. Holding the watch in his hand, he counted the rabbit's breathing.
Make a note in your notebook.
After a while, Jin Na squatted down next to him, stretched out her hand to touch the rabbit's head, wrapped the long hair around her fingertips and played with it. After playing for a while, she asked in a low voice:
"Mr. Nordmark, why do you keep pouring water into this rabbit's belly?"
...I am not pouring water into its stomach, but into its lungs. Gretel opened his mouth and wanted to explain, but he was afraid that the dwarf girl would be frightened. While he was thinking about how to make up a story, Gavin sat down next to him and asked more questions.
:
"Yes, yes! Gretel, grandpa said that you were pouring water into the lungs of animals along the way, just to practice that... lung cleaning... and so on. How is your practice now? Is it ready for use?"
"Lung cleansing?"
"What is lung washing?"
"Can the lungs also be washed? Is it possible to pour water into it without choking?"
Several voices asked garbled questions. Gretel turned around and saw that except for Hanna who was still standing in front of the stove, several other dwarves had gathered around. They were either bending over and supporting their knees, or simply sitting on the ground, staring intently.
He sees.
Gretel hesitated to answer. He was not 100% sure when he was doing animal experiments on things like lung washing, so how could he dare to try it on humans?
Besides, even if you fail to treat ordinary dwarves, the problem will not be too big. Treating the king's son, let alone causing a lot of complications, even if the effect is not satisfactory, it will be a diplomatic accident in a minute!
Seeing that Gretel refused to speak, Gavin said "Hey" and stretched out his hand to shake his shoulder. Halfway through, Prince Rothega grabbed his hand and dragged him back:
"Don't be like this, Mage Gavin Nordmark has already helped us a lot. If he wants to tell us what he is studying, he will naturally tell us. If he doesn't want to tell us, we shouldn't force others to do it."
As he spoke, he nodded and smiled at Gret, let go of his hand, and was the first to get up and walk away. Gret suddenly felt something in his heart:
"etc!"
"how?"
Gretel took out a glass and handed it to him: "Spit in it." After saying that, he took something out of the space bag:
A large graduated flask, a large water tank, a thick glass piece, a curved glass tube, a funnel, clay... I picked it out and shouted:
"Bernard, fetch me a bucket of water!"
Before the barbarians could rush over, Gavin quickly ran over to carry water. Gretel instructed him to fill the sink half full, then filled the glass bottle with water, covered it with a thick glass piece, and poured it upside down.
sink.
Then he removed the glass piece, inserted one end of the bent tube into the mouth of the bottle, connected the other end to the funnel, and sealed it tightly with glue. After everything was done, he waved to Prince Rosegar:
"Come on, take a deep breath and blow into the funnel! Press your face on it, don't let it leak. Blow as hard as you can!"
Rotherga didn't know why, so she held the spitted glass and followed Grete's request, blowing hard. Grete squatted on the side and looked at the scale of the bottle, counting one by one:
"2600ml...2700...2800..."
What is the normal lung capacity of a dwarf?
Lung capacity is affected by factors such as age, gender, stature, respiratory muscle strength, and elasticity of the lungs and thorax. Dwarfs are much shorter than humans, so it is reasonable for them to have lower lung capacity than humans; however, these are powerful
A warrior, similar to an athlete, should have much higher lung capacity than an ordinary person...
The vital capacity of a normal human male is generally 3500 to 4000 ml; athletes can reach more than 6000 ml; for dwarfs, dwarfs who exercise for a long time, what should be the normal value?
Grete scratched his head. If there were references to medical books from past lives to treat humans, cross-racial medical research would be too difficult for him.
——Is there any way to trick that Kai over and test his lung capacity?
