1. ## Acnologia's Roar Rererererecalc

Phew, this is going to be hard….

EDIT:

Redid the crater volume to a spherical cap. Oh well, still worth it.

First I’ll scale Acnologia’s Wings:

Average Human arm = 0.7 meters(source)(?)
Freed’s Arm = 55 px
Ratio = 0.0127272727272727 m/px
Acno’s Eye = 34 px = 0.43272 meters

Acno’s Eye = 0.43272 meters
Acno’s Eye = 19 px
Ratio = 0.0227747368421053 m/px
Acno’s Mouth = 68 px = 1.54868 meters

_____
Acno’s Mouth = 1.54868 meters
Acno’s Mouth = 25 px
Ratio = 0.0619472 m/px
Acno’s Wing = 194 px = 12.017 meters

Acno’s Wing = 12.017 meters
Acno’s Wing = 112 px
Ratio = 0.1072946428571429 m/px

Beam Diameter = 120 px = 12.87535 meters
___
Acno’s Beam = 12.87535 meters
Acno’s Beam = 2 px
Ratio = 6.437675 m/px

Explosion Diameter = 750 px = 4828.25625 meters
Tenrou Diameter = 545 px = 3508.532875 meters
Explosion Height = 590 px = 3798.22825 meters

First, we’ll calculate the volume of destroyed rock.
Explosion Diameter = 4828.25625 meters
Explosion Diameter = 270 px
Ratio = 17.8824305555555556 m/px
Explosion Radius = 4828.25625/2 = 2414.128125 meters
Going to assume that the crater height is as big as the explosion height(should be a fair assumption, and if not I’d like to hear opinions on what it should be)
Crater Height = Explosion Height = 3798.22825 meters
____
Spherical Cap Calculator:
https://www.calculator.net/volume-calculator.html
V = 63462094623.829 m^3

Violent Fragmentation(Low-End):
E = 63462094623.829 m^3 * 1000000 * 69 j/cc = 4378884529044201000 joules = 1.04 gigatons(Small Island level)

Pulverisation(High-End):
E = 39289662293.682 m^3 * 1000000 * 214.35 j/cc = 8421739112650736700 joules = 3.25 gigatons(Small Island level)

Now to calculate the vaporized water. First we’ll find the volume:

Explosion Diameter = 4828.25625 meters
Explosion Diameter = 418 px
Ratio = 11.5508522727272727 m/px
Water Height = 45 px= 519.7883522727272715 meters
Cylinder Volume:
V = 9516933778.9332 m^3

However, we should keep in mind that the island itself was in the place of this water, and since Acno didn’t destroy the island due to Fairy Sphere, we’ll have to take out the volume of the island.
Tenrou Diameter = 3508.532875 meters(from earlier), so:
Vtenrou = 5025364010.1113 m^3

V’ = V – Vtenrou = 4491569768.8219 m^3
Density of water = 1000 kg/m^3
Mass = V’ * D = 4491569768821.9 kg
Specific Heat of water C = 4186 J/kg
Average Ocean temperature is 15 degrees, so:
100-15 = 85 degrees
E1 = 85 * 4186 * 4491569768821.9 = 1598145439444520239 joules
Heat of vaporization is 2257000 J/kg
E2 = 4491569768821.9 kg * 2257000 J/kg = 10137472968231028300 joules
E = E1 + E2 = 11735618407675548539 joules = 2.804 gigatons(Small Island level)

<=>

Low-End:
1.04 + 2.804 = 3.84 gigatons(Small Island level+)
High-End:
3.25 + 2.804 = 6.05 gigatons(Island level)
Phew, took me a while. I'm open to critizism. Still not sure whether violent fragmentation or pulverisation should be used

Well, at least it's better than the NF 80 megatons

2. Interesting.

I hope you're prepared good sir

3. Actually gotta give props to Sir Torch for trying to learn the feats of series before arguing a biased point and picking up how to calc the feats himself. He's got motivation that's for sure, repped.

4. Just glossed over it very quick and could not find any major flaws. Surely worth a closer look.

5. Should also note that this was Acnologia weaker than prima and is not playing with FT

6. The problem is the island is much larger than that given the fact we can't even see the GH ship compared to it.

7. And it begins

8. i swear on god i'd support going xenforo just to threadban rax.

Come on, mang.

If a few hundred long ship isn't visible from a clear overhead view then there's no way the island is 5km.

That's silly

10. Tenrou Diameter = 545 px = 3508.532875 meters

That's strange. According to Rax, Tenrou Island is about 80 kilometers long.

Good job, by the way. Island level from busting an island, nice.

Explain why you can't see the GH ship at all then if the island is only 3500m wide

You also can't scale this way.

The explosion is still expanding and clearly was much larger than the island.

You can see how big the island was in proportion to the distance Acno was and then the same with the crater.

The crater was vastly larger.

12. what have you done

Eh, I don't care about that, buddy. I was just making a joke. That's it. It looks like I shouldn't do that.

This is Sir Torch's thread, so let's not start a pointless discussion which probably would be over 10 pages long.

Yes, I've sinned.

14. I'm just saiyan.

The island being 3.5km makes no sense given the arc.

The GH Ship was massive and yet they had a good deal of trouble finding it.

If by good deal of trouble you mean finding it practically instantly then sure.

16. Well at least you didn’t get. 300 meter Acnologia

40 chapters later.

Can you explain why the GH ship was never visible in any of the overhead shots and didn't take up a massive chunk of the island?

Given that the attack starts here and the GH ship isn't visible at all from being equal to or shorter than that slope of the island, that part should be at least as tall as the GH ship is.

So I realized there's a good way of calcing his Tenrou roar using angular size to find the depth of the crater.

Phew, this is going to be hard….

I’m going to calculate the depth of the crater.
Object =2 * arctan(Object_Size/(Panel_Height/(tan(70/2))) = 2 * arctan(30/(272/tan(70/2))) = 8.832233979022 degrees
The crater should be 4828.25625 meters, so:
http://www.1728.org/angsize.htm
Height = 31259 meters

R = 4828.25625/2 = 2414.128125 meters
Cylinder Calculator:

V = 572328779001.93 m^3
Violent Fragmentation(Low-End):
E = 572328779001.93 m^3 * 1000000 * 69 j/cc = 39490685751133170000 joules = 9.438 gigatons(Island level)

Pulverisation(High-End):

Now to calculate the vaporized water. First we’ll find the volume:

Explosion Diameter = 4828.25625 meters
Explosion Diameter = 418 px
Ratio = 11.5508522727272727 m/px
Water Height = 45 px= 519.7883522727272715 meters

29.320 + 2.804 = 32.124 gigatons(Island level)
Phew, took me a while. I'm open to critizism. Still not sure whether violent fragmentation or pulverisation should be used

Well, at least it gives Acno a higher number than before(excluding the whole etherion scaling)
Now I might be missing something or you missed a step but did you scale the crater as a cylinder?
