My Hero Academia: Storm Dispersion Pixelscaling Problems

[GodlyCharmander]

I'll get straight to the point, the original calculation uses a 2D pixelscaling, in a 2.5D image. I understand this is okay when it's the only option, but we do have a 2D image featuring the same wall, and the entire island (Please ignore the lines on the image, I took from other calc a friend of mine did, it uses a different wall size):

Why use that?

Because 2D -> 2D is more accurate than 2D -> 2.5D.

There's also the problem that, it's utterly impossible for the cloud to be 1.003kg/m³ being over 20km above the ground. If that was the case, it would be denser than air, and would be able to stay so high in the first place. So the storm is bigger, but also far lighter.

Anyway, I'll replace the values with the new scaling just to see how it'd go. If my complains are valid, I will put this into a blog.

Spoiler: New Scaling

Wall: 82.06m/22px
Island: 1047px = (1047/22)*82.06 = 3905.31m

Now let's replace the values. That's the fun part.

Island Diameter = 2.54 km (Old)/3.90531km(New)

Storm Radius = (23.60/2.54)*3.90531 = 36.2855574803/2 = 18.1427787401 km

Storm Height = (14.06/2.54)*3.90531 = 21.617582126km

We put these values on this Cylinder Calculator to get the volume of this storm cloud.

Volume = 22354.481370966 km^3 or 22354481370966 m^3

Now, the storm is over 20km in height, ontop of being over 10km above the ground, so the air density should be 0.01841kg/m³, as opposed to the normal 1.007kg/m³

Density of cloud air below 0.01841kg/m³ kg/m^3. (But I'm gonna use it as a high end)

Mass = 22354481370966 x 0.01841kg/m³ = 411546002039 Kilograms

The air pressure hit the storm at 0:30, and it was completely dispersed by 0:46, making the timeframe 16 seconds.

The distance the storm was blow away was 28.02 kilometers or 28020 meters in the original calc. (28.02/2.54)*3.90531 = 43.0814118898km or 43081.4118898m

Speed = 43081.4118898/16 = 2692.58824311 m/s

Kinetic Energy = 1/12*411546002039*(2692.58824311)^2 = 2,4864345e+17 Joules, 59,42 Megatons of TNT (City Level)

OOOOOOOF

But hey, at least it's not an outlier anymore, right? But we also need to do that to the currently accepted calculation.

Spoiler: New Explosion Radius

Original
Island: 3905.31m/58px
Explosion Diameter: 1366 px = (1366/58)*3905.31 = 91976.7837931 meters

Explosion Radius = 91976.7837931 / 2 = 45988.3918965 meters = 45.9883918965km

Formula: Y = (x / 0.28)^3 / 1000

Y is the yield in megatons, and x is the radius in kilometers.

Y = (45.9883918965 / 0.28)^3 / 1000 = 4430.68195848 megatons

Divide this by two since it's non-nuclear, and divide by two again because both Deku and Bakugo did this.

Y = 4430.68195848 / 2 = 2215.34097924 megatons

That makes 1.11 Gigaton for Deku and Bakugo. (Large Mountain Level)

Can you please send your source for the cloud density thing ?, that is relevant to a lot of verses not only my hero

I already did in my recalc. But here it is: https://www.engineeringtoolbox.com/standard-atmosphere-d_604.html

The air pressure hit the storm at 0:30, and it was completely dispersed by 0:46, making the timeframe 16 seconds.

Yeah that's the problem, the storm was actually dispersed in an instant.

 

[GodlyCharmander]

Yeah that's the problem, the storm was actually dispersed in an instant.

It took about 3 seconds to disperse, right? This would probably make it Large Mountain too. (it did, actually.)
I see, what's your opinion about the pixelscaling itself?

 

[GodlyCharmander]

Bump

 

[SuperStar]

I'm confused, is this an upgrade or a downgrade?

 

[Theendzero13]

It seens to be an upgrade for the island size, but also trying to downgrade the storm feat by changing the rules of cloud calculations based on informations charmander found

I was not the one who found the information, it was someone in the currently accepted calc (linked in the New Explosion Radius)
It also upgrades the accepted calc.

Ok them

Since both the explosion and the dispersion gave us high 7-A results it seens consistent on itself

 

[XSOULOFCINDERX]

Bump.

 

[Theendzero13]

Since the feat my hero feat was deemed an outlier regardles , maybe charm should make a cloud calculations revisions instead, because the evidence given seens pretty damming against our current standards

 

[XSOULOFCINDERX]

Idk. I'm just curious as to why this hasn't been touched in over a week.

Because the feats got deemed an outlier anywhay, so everybody kinda lost interest

 

[TheRustyOne]

Regardless of it being an outlier it could be useful.

And who knows, maybe future feats will pop up and it won't be an outlier anymore.

Like Shigaraki's? Wasn't the Low-Ball Calc of that City Level?

What shigaraki calc?

 

[TheRustyOne]

The manga is still ongoing, can't say how it's going to turn out.

There could be some crazy feat in the future that happens to jump the characters up to 7-A or something. Or maybe the opposite... I don't know.

Where? Can I see it?

 

[Theendzero13]

Where? Can I see it?

I think it is my hero general movie and scaling revision

 

[Gitagon]

Didn't people say this was an outlier. Anyway it's good to keep the calc in mind when we eventually get another feat of this scale.

 

[Therefir]

The problem is that people keep finding ways to make the island bigger.

I have no problem with GodlyCharmander's measurements, but our cloud calculations are still a mess, we use a density that is heavier than air at high altitudes and no one bats an eye, and why even use air density when in most cases there's no proof that a vacuum was created?

All Might's feat uses water content so it should be still fine.

Exactly what i am saying a widespread cloud calculations revision needs to happen

 

[XSOULOFCINDERX]

If you want it to happen so bad then why not do it yourself?

 

[Theendzero13]

Doing such a massive thread who affects a lot of major verses, who is sure to cause polemic, on mobile, with shitty edition abilities ?? Hell no i am outa here

 

[GodlyCharmander]

It doesn't seem to be that easy. We can't just use Air Density for higher altitudes because it would be lower than that to keep itself in the air, so we would need to find consistent cloud densities based on height. I could do some digging to help with that, but this would change... uhhh, SOME verses.

Luckily Saitama doesn't depend on his cloud feat anymore.
