The Gundams of the world team up to stop the Devil Gundam's tentacles from reaching the Earth and devouring it. These tendrils are so massive that they can be seen even as they come around the curvature of the Earth. The Earth has a radius of 6378.1km.
R = (h/2) + c^2/(8h)
= (73/2) + 1931^2/(8 X 73)
= 6421.36473 pixels
6421.36473 pixels = 6378.1km
1 pixel = 6378.1km/6421.36473 = 0.993262378km
0.993262378km X 33 = 32.7776585km
32.7776585km/2 = 16.3888292 kilometers (16388.8292m)
0.993262378km X 688 = 683.364516km
0.993262378km X 1931 = 1917.98965km
To make our work much easier, the previous shot has the appendage in question seen as straight.
1 pixel = 32.7776585km/61 = 0.537338664km
0.537338664km X 1588 = 853.293798km (853293.798m)
Volume as a cylinder.
V = πr^2h
= π X 16388.8292^2 X 853293.798
= 7.20019602e14m^3
As per almost all of my calcs relating to the mass of machines, I'll be using the values for the light ship container vessel 2700TEU, which has a mass of 102.56kg/m^3.
M = 7.20019602e14 X 102.56kg
= 7.38452104e16kg
With our size and mass, we can find our speed!
1 pixel = 1917.98965km/734 = 2.61306492km
2.61306492km X 135 = 352.763764km
T = 1s/24
= 41.6666667ms X 9
= 0.375s + 2s
= 2.375s
T = 352.763764km/2.375s
= 148532.111/340.29
= Mach 436.486852
KE = (0.5)mv^2
= (0.5) X 7.38452104e16 X 148532.111^2
= 8.14578688e26 joules
= 194.68897896749521692 petatons
It takes nine Gundams to destroy this tentacle.
E = 194.68897896749521692 petatons/9
= 21.6321088 petatons
Just one more thing...the Gundams all zoom forward along the length of the tendril to destroy it, which when you consider just how big it is, is incredibly impressive. As all the Gundam's travel at different speeds, we'll have a measurement of the Gundam closest to the tendrils 'maw' and the one furthest in each.
0.24644856km X 133 = 32.7776585km
0.24644856km X 231 = 56.9296174km
0.24644856km X 342 = 84.2854075km
0.24644856km X 152 = 37.4601811km
32.7776585 + 37.4601811km = 70.2378396km
56.9296174km + 84.2854075km = 141.215025km
T = 1s/24
= 41.6666667ms X 20
= 0.833333334s + 1s
= 1.83333333s
(Low end)
T = 70.2378396km/1.83333333s
= 38311.5489/340.29
= Mach 112.584998
(High end)
T = 141.215025km/1.83333333s
= 77026.3774/340.29
= Mach 226.355101
Final Results
Neo Japan's size = 683.364km
Devil Gundam's tendril circles the world (speed) = Mach 436.487
Devil Gundam's tendril circles the world (kinetic energy) = 194.689 petatons
Mandala Circle individual Gundam power = 21.632 petatons
Gundams destroy Devil Gundam's tendril (low end) = Mach 112.585
Gundams destroy Devil Gundam's tendril (high end) = Mach 226.355
