Chapter 374 What Is the Normal Lung Capacity of a Dwarf?

The steam engine puffed and puffed.

The generator rotor sputtered.

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 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. Layers of ore and charcoal are stacked on top of each other to create a fire in the furnace. The furnace was filled with orange and red, and only the most experienced eyes could see through the flames and see the ore turn red, soften, and turn into pig iron...

Everyone is busy. Only Grete, who even contributed generators and oxygen-generating equipment, couldn't water the rabbits. He moved closer to the furnace. He was afraid of heat and ashes, so he had to make himself a [cold-resistant and heat-resistant], squatting on the side and watching the strings of bubbles in the electrolyzer.

"Crack."

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

The electrolyzer is no longer bubbling!

out of battery?

What's wrong? A fuse tripped? No, this broken circuit doesn't have a fuse, so it doesn't matter if it jumps. Is the mercury arc rectifier broken? God bless you, but don’t be!

He stood far away, used his mage's hand to open the wooden box containing the rectifier, and looked at it carefully. There was darkness in the box, no blue sparks dancing, no pricking sounds. Then I threw myself in front of the generator and took a look, and there was a mushy smell...

"Stop!" he shouted:

"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 is made larger, 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), the number of turns of the coil, and the diameter of the wire. How to relate it specifically, how many turns and how big a magnet do you need to make to match this steam engine?

Grete said that he was sorry, but when he was in high school, he only learned that cutting a wire through a magnetic field could produce an electric current. 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. Relying on the fact that there was no one else on site who knew how to generate electricity, Grete bit the bullet and assumed the commanding role:

Find copper wire!

Insulate the copper wire!

Find a larger 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 block, and see which way the iron block swings.

Build the frame, fix the magnets, rewind the wire...

Gretel moved her mouth, Jinna moved her hands, and a group of men started to strike. The ready-made generator is stuck there, and making a bigger one is just like that. In the eyes of the dwarves, well, it's just a half-day effort.

Moreover, because Gretel 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. Set it up, reconnect the wires, and get started!

In the furnace, the blazing white fire rose again.

Gretel touched here and there to make sure that the coil was not heating up and that the electrolyzer was operating normally. He did not need to think about maintenance. Then he returned to the corner and continued to watch the rabbit. Holding the watch in his hand, he counted the rabbit's breaths one by one, and wrote down a note in the notebook after a while.

After a while, Jin Na squatted down next to him, reached out to touch the rabbit's head, and twisted the long hair around her fingertips to play with it. After playing for a while, he 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, wanting 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:

"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 Hanna who was still standing in front of the stove, several other dwarves were surrounding him. Either bending over and holding up his knees, or simply sitting on the ground, staring at him with burning eyes.

Grete hesitated to answer. He is not 100% sure about lung cleaning and other animal experiments. How dare he try it on humans?

Besides, even if you fail to treat ordinary dwarves, the problem won't 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 become a diplomatic accident in a minute!

Seeing that Grete refused to speak, Gavin said "Hey" and reached out to shake his shoulder. He reached his hand halfway, but was grabbed by Prince Rosega and dragged back:

"Don't be like this, Gavin. Master 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 it on others."

As he spoke, he nodded and smiled at Gret, let go of his hand, and was the first to get up and walk away. Grete suddenly felt something in her 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 took it out and shouted:

"Bernard, get me a bucket of water!"

Before the barbarians could arrive, Gavin quickly rushed over to fetch water. Gretel instructed him to fill the sink half full, fill the glass bottle with water, cover it with a thick glass piece, and put it upside down into the sink.

Then remove the glass piece, insert one end of the bent tube into the mouth of the bottle, connect the other end to the funnel, and seal it tightly with glue. After finishing everything, he waved to Prince Rosega:

"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!"

Rosega didn't know why, holding the spitted glass, she followed Grete's request and blew hard. Grete squatted beside him and looked at the scales on the bottle, counting 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 shape, strength of respiratory muscles, and elasticity of the lungs and thorax. Dwarves are much shorter than humans, so their lung capacity should be lower than humans; however, these are powerful warriors, and their lung capacity should be much higher than that of ordinary athletes...

The lung 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?

Gretel scratched his head. If there are references to medical books from past lives when it comes to treating humans, cross-racial medical research is really too difficult for him.

——Is there any way to trick that Kai over and test his lung capacity?
