Oooooookay, so I finally fixed it.
Re-do of the first calc in this blog.
Turns out the crater has a determined width and depth we can find out using the taxi in the crater.
Also I think I might be able to correctly guess how far Batman was away from the bombs basing on where he was standing next to the dogs.
Context here (Detective Comics #832)
Heights and surface area[]
Since this makes of inverse square law, I'll use Bats' height and weight for surface area with this calculator.
Batman is 6ft 2inch and he just so happens to be 210 lbs. Slap those in the calculator and we get 2.2 m^2. Divide by two and its 1.1 m^2.
Pixel-Scaling and volume[]
Pixel-scaling part 1[]
Pixel-scaling part 1 Correction: Forgot to add "deg" after 70 as the Calculation Guide commands and got the panel height and pixel-height of the dog wrong as well. Fixed now.
First we figure out how far the dog is from the explosives. The dogs are near Batman so it should be okay to use.
Dog looks like a German Sheperd, which usually has a height of 60-65 cm. I'll just assume the average of 62.5 cm or 0.625 m.
Dog (red) is 100px tall (1356-1456px). Panel height (yellow) is 236px (1355-1588px).
2atan(tan(70deg/2)*(object size= 100px / panel height= 236px)) = 0.576849582 rad or 33.05 degrees.
Slap the values into here and we get 1.0533 meters, which is the true distance of Batman being away from the explosion. I'd say this is an okay assumption given the fact that he and Fisk are in a circular area without much room to move since, well... dogs. And the bomb is also quite far away from the doors and closer to the arena's center with both the men being locked in and having no way to get out in time.
Pixel-scaling part 2[]
We already figured out the length of the crater to be 33.124 meters AKA 3312.4 cm from the previous calc.
But the main thing to solve now is the crater depth and width.
The car in the crater is a first-gen Ford Crown Victoria non-facelift variant seeing as how it doesn't have a grill, meaning it has a length of 539.5 cm, but all first-gen models both pre-facelift and post-facelift are 197.6 cm wide.
First, the crater width.
The Crown Victoria (green) has a width of 100px (348-448px). The crater (red) is 335px wide (401-736px).
335/100= 3.35x and 197.6*3.35= 661.96 cm
Now the crater depth. The crater's depth seems to reach the rear half of the front wheels.
In the second picture, the Crown Victoria (Red) (I am using a picture of the second generation model since side shots of the first-gen are hard to come about but the lengths are pretty much identical so it'll make a negligible difference), bumper to bumper, is 585px (27-612px). The length from its rear bumper to the rear half of the front wheel (yellow) is 476px (136-612px).
585/476= 1.2289915966386554621848739495798x and 539.5/1.2289915966386554621848739495798= 438.98 cm.
Volume[]
Correction: I used the cuboid formula when the crater isn't even a cuboid, it's an elliptical cylinder Volume for elliptical cylinder= Volume (V) = π × A × B × h, where A is the semi-major axis (Half of length) and B is semi-minor axis (Half of width)
Volume (V) = π × 1656.2 × 330.98 × 438.98= 755977968.097 cm^3
Forgive me for the blunder.
Calc[]
Concrete has a v. frag of 17-20 J/cc. The explosion essentially reduces it to tiny bits but not enough to be categorized as pulverization. Using the low-end of 17 J/cc for safer estimates.
755977968.097*17= 12851625457.649 J or 3.0716 tons of TNT (Large Building level)
Time to slap on the inverse-square.
(3.0716) / (4π((1.0533)^2))= 0.22031832773 tons of TNT (Small Building level+). Now we multiply half of Batman's surface area with that (1.1 m^2) and we get 0.242350160503 tons of TNT or 1013993071.545 J (Small Building level+)
Not really much of an increase after the correction but hey.
All in all,
RIP 8-C BATMAN
