"I wonder if the ship's resistance was" wave resistance "," pressure resistance "or" friction resistance "..."

It is precisely wavemaking resistance, viscous pressure resistance and viscous friction resistance.

You heard about the wave resistance from Jin a long time ago.

Wavebuilding resistance is the loss due to it, which causes waves as the hull progresses, and increases proportionally to the squares of speed.

I have fluid dynamics to predict and calculate these resistances, but unfortunately it was the first thing I learned at a science and technology university, and Jen didn't even know the details.

As such, Jen's knowledge of such ships... No, '400 years ago' Jen probably didn't seem to have opened it all, 'now' Jen thought.

That's not impossible either. Because I can do anything with too much power, such as some inefficiency.

That was the same on the ship.

"Yeah. There are other things like 'pressure resistance' and 'friction resistance'"

"I kind of get 'pressure resistance'. That's resistance when you take water from the front, isn't it?

"Well, I guess I could say that. … more precisely pulled back by the negative pressure of a vortex or something that can be behind the ship… Apparently"

"Oh, I see!

Only Marcia, who had repeated a lot of tests in the water, seemed to understand this explanation of Jen well.

"And then there's 'friction resistance'. I think you can tell this if the water is a more sticky liquid"

"I see. You'll see."

"Perhaps Marcia's experiments look at 'wave resistance' and 'pressure resistance'. And maybe" friction resistance "is overlooked."

In this explanation from Jen, Marcia felt like scales had fallen from her eyes.

"By the way, the outside of the ship I built drops the friction coefficient as much as possible in Surface Treatment."

The lower the experiment, the better.

"I see, and with that, Gin's ship is excellent!

Marcia looked neat when the point was made.

"Oh, so in an emergency, we'll also use 'Water Avoidance Boundaries'."

This makes the hull immediately out of contact with water, so "friction resistance" can be ignored, and "wave resistance" and "pressure resistance" are eliminated, so it is fast.

"Well, maybe we can wave, but it's not the ship that's making that wave, it's the junction, so that means the propulsion of the ship itself won't be lost."

That's what I'm talking about.

"Yeah, I knew Gin's ship was special. It's an anomaly. It's unreasonable."

"Whoa."

"Ha, it's a joke. But I want to do something about it."

Jen knew very well, and affirmed Marcia's point.

"Because I needed the vast majority of what I've been making. But if it's purely a hobby, I think you can stick to it, as Marcia says."

There is little that Jen has made hobbyistically. Reiko or Golem, and aircraft, ships, spacecraft... were mostly meant to protect a peaceful life.

Hardly enough to have a wooden ship, Shark, built with ties.

"Well, do you want to resume the experiment?"

After a break, Marcia stood up. Jen also continues to rise.

Good luck with that.

"Yeah, of course."

And Jen and Reiko Mini went back to the lab.

"Father, speaking of which, Mr. Stearena started making something, right?

"Huh?"

Jen, who was intrigued by Reiko Mini's remarks, decided to go to the workshop in the Steer Arena.

"Whoa."

It was green there...... no, it was overflowing with young grass colored light.

"Olive stone, is it"

Mini Reiko sitting on Jen's shoulder told him to squeal.

Olive (kanlan) stone is a volcanic mineral.

The bitter soil olive stone in it is young grass or green apple coloured and is called peridot, or olivine.

Apparently the name Olivine also comes from the olive color.

And since it is a volcanic mineral, a considerable amount was produced in Penglai.

This is how Perido, one of the five color golem maids while snakefoot, is named because the color of his eyes is green.

"Oh, Jin."

Jen noticed that the steering arena was working on it with all its heart.

"Are you making a golem?

"Yeah. As you can see, now we have the green 'Peridot Golem'."

Looks like a steering arena, Jen thought.

She used to make crystal golems made of transparent crystals and topaz golems made of blue topaz.

Now the Peridot Golem.

"Engineering magic is convenient. There's no such thing as a big peridot."

Because peridots are formed on relatively fast cooling magma tops, there are few large crystals and many small grain ones.

So the Steer Arena used the engineering magic "fusion" and "homogenization" to create a giant peridot, and used it to make a golem.

"This is beautiful too..."

The shape of the steering arena is always stunning, but this time the golem didn't leak into the example again, and no, it's the most stunning thing ever, Jen praised.

"Thank you. I'll be done by dinner today, so I'll show you."

I'm looking forward to it.

Jen followed the scene when he was not comfortable watching much of the production process.

"Is it the influence of your father's creation of Jackie?"

Jen was back at the 'house' for lunch.

By the way, for lunch today, members of the Jen family said they would prepare and eat with each other, so Elsa and I can't get in the water... I have a mini Reiko...

"Mmm, it seems that Brother Rai is also looking to create a new 'Black Knight' or 'Neon' generation."

"Reinhardt would be..."

I wonder if anyone else is making something, if Jen shrugs,

"I'm not making things, but you're studying something, Saki."

"Saki..."

Jen was convinced that he was originally an alchemist, or chemist.

"And Beana's making something, too"

"Right."

Beana is also a common-law magician (Magicraftsman) once known as "Craft Queen," so it's not surprising that she's starting to do that.

"Elsa make something too?

Former squire Edgar now serves Shu Nido.

"Yeah, I'm good"

Elsa said she had no particular hope of saying so.

But go on,

"I want to study healing magic and plant magic."

That's what I said.
