It's not that hard to open a hospital in another world, right?

Chapter 374 What is the normal value of the lung capacity of a dwarf?
The steam engine was puffing.

The generator rotor rattled and turned.

The electrolytic tank was bubbling and bubbling, oxygen was blowing out silently from the iron pipe, and beside the magma pool, white fire rolled up.

Jin Na ran from the steam engine at one end to the oxygen tube at the other end. Gavin kept his mouth shut and held the shelf and did not dare to move. Prince Fei Lai and Prince Rotherga sat on the ground with their feet in front of them, pulling the bellows desperately.Hannah rolled up his sleeves high, the muscles in his arms stretched out, staring at the ore smelted in the white fire.

With the continuous blowing of oxygen into the furnace, the flame was raised to an extremely high temperature, and the ore smelting was exceptionally smooth.Layers of ore and charcoal are put together and ignited in a furnace.The hearth is orange-red, and only the most experienced eyes can see through the flames that the ore sand turns red, softens, and turns into pig iron...

Everyone has their hands full.Only Gretel, who even donated generators and oxygen generators, couldn't even water the rabbits.Going to the furnace, he was afraid of heat and dust, so he had to make himself a [cold and heat resistant], squatting aside, watching the strings of bubbles in the electrolytic tank.

"Clap."

There was a sudden soft sound.Between the roar of the steam engine and the whirring of the bellows, there is almost no sense of existence.Gretel suddenly jumped up:

Electrolyzer, stop bubbling!

out of battery?
What's wrong?Fuse tripped?No, there is no fuse in this broken circuit, it doesn't matter if it trips.Is that a bad mercury arc rectifier?God bless, but don't be!
He stood far away, opened the wooden box containing the rectifier with the hands of a mage, and looked carefully.The inside of the box was completely dark, and there were no faint blue sparks beating or crackling noises.Then I jumped in front of the generator and saw, yes, a smell of paste...

"Stop!" he yelled:

"The motor is burned!"

"The white fire is gone!"

Hannah also shouted at the same time.All of a sudden, all eyes were on Gretel.Gretel scratches his hair:

"Uh... well, the steam engine is too big, the generator is too small, let's make a big one..."

"How big is it?"

"I don't know... Anyway, the magnet is a big one, so 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 strength of the magnetic field), how many times the coil is wound, and the diameter of the wire.How to associate it specifically, how many turns and how big a magnet should be to match this steam engine?
Gretel said, sorry, when he was in high school, he only learned that electric current can be generated by cutting a magnetic field, and then, goodbye.

At last he still had basic common sense: if the coil is burnt, it must be because the steam engine output is too strong, and the generator is too small, just make a bigger one.Relying on the fact that there was no second person on the scene who knew how to generate electricity, Gretel bit the bullet and assumed the command task:
Find copper wire!
Insulate the copper wire!

Get a bigger magnet and cut it into a rectangle!What?Magnetic field strength?Hang a piece of iron in the middle, let the two magnets face each other across the iron piece, and see which way the iron piece swings, isn't it over!

Build a shelf, fix the magnets, rewind the wires...

Gretel moved his mouth, Jinna moved, and a group of men fought.The ready-made generator is poked there, and a bigger one is made as it is. In the eyes of the dwarves, heck, it's just half a day's work.

Moreover, because Gretel couldn't tell how big it should be, after finishing a set of generators, Jinna made another smaller one with the remaining materials.Rack it up, reconnect the wires, and go!
In the hearth, the blazing white fire rose again.

Gretel fumbled here and there to make sure that the coil wasn't heating up and the electrolyzer was operating normally, so he didn't need to try to maintain it. He then retreated to the corner and continued to watch the rabbit.Holding the watch in his hand, he counted the rabbit's breath, and wrote it down in the notebook after a while.

After a while, Jinna squatted beside him, reached out and touched the rabbit's head, and played with the long locks around her fingertips.After playing for a while, he asked in a low voice:
"Mr. Nordmark, what have you been pouring water into this rabbit's stomach for?"

...I didn't pour water into its stomach, but into its lungs.Gretel opened his mouth, wanting to explain, but afraid that the dwarf girl would be frightened.Just thinking about how to make up a story, Gavin sat down next to him and asked:

"Yeah, yeah! Gretel, Grandpa said that you were pouring water into the lungs of animals all the way, just practicing that... lung washing... and so on. How are you doing now? Can it work?"

"Lung washing?"

"What is lung washing?"

"Can the lungs be washed too? If you pour water into it, won't you choke on it?"

Several voices asked miscellaneously.Gretel turned his head and saw that except for Hannah who was still tied in front of the stove, the other dwarves had surrounded him.Or bent over to support his knees, or simply sat on the ground, staring at him with burning eyes.

Gretel hesitated to answer.He is not 100% sure about washing the lungs, even if he is doing animal experiments, how dare he try it on humans?

Besides, even if the treatment of ordinary dwarves fails, the problem will not be too big.Treating the king's son, not to mention causing a lot of complications, even if the effect is not satisfactory, it will be a diplomatic accident in minutes!

Seeing that Gretel refused to speak, Gavin let out an "hey" and was about to shake his shoulder with his hand.He stretched his hand halfway, but was grabbed by Prince Rothergar and dragged him back:

"Don't be like this, Gavin. Master Nordmark has helped us a lot. If he wants to tell us what he is studying, he will naturally say it. If he doesn't want to say it, we shouldn't force others to be difficult."

As he spoke, he nodded and smiled at Grete, let go of his hand, and was the first to get up and walk away.Gretel suddenly moved in his heart:
"and many more!"

"how?"

Gretel took out a glass and handed it to him, "Spit into it." After speaking, he took something out of the interspatial bag:

Large flasks with scales, large sinks, thick glass sheets, curved glass tubes, funnels, cement... shouting while digging:
"Bernard, fetch me a pail of water!"

Before the barbarians rushed over, Gavin had already rushed over to fetch water.Gretel directed him to fill the sink half full, fill the glass bottle with water, cover it with a thick glass piece, and plunge it upside down into the sink.

Then remove the glass sheet, plug one end of the elbow into the mouth of the bottle, connect the other end to the funnel, and seal it firmly with glue.After everything was done, he waved to Prince Rothergar:

"Come on, take a deep breath and blow into the funnel! Press your face on it, don't let it leak, blow like hell!"

Rotherga didn't know why, holding the glass that had spit on her mouth, she followed Gretel's request and blew vigorously.Gretel squatted by the side and looked at the scale on the bottle, counting them one by one:

"2600ml... 2700... 2800..."

What is the normal lung capacity of a dwarf?
Vital capacity is affected by factors such as age, gender, body size, strength of respiratory muscles, and elasticity of the lungs and thorax.Dwarves are a bit shorter than humans, and their lung capacity should be lower than humans; however, these are powerful fighters, analogous to athletes, and their lung capacity should be much higher than ordinary people...

The lung capacity of normal human males is generally 3500 to 4000 ml; athletes can reach more than 6000 ml; dwarves, dwarves who exercise for a long time, what should be the normal value?

Gretel scratched his head.It would be too difficult for him to treat human beings with reference to medical books from previous lives and interracial medical research.

——Is there any way, just trick that Kai over here and test his lung capacity too!
