Luffy’s Jet Pistol
Luffy’s Jet Pistol creates a shockwave which sends an unsuspecting Rob Lucci flying into some crates. Luffy had used the same technique earlier against Blueno, but I felt that one wasn’t worth calculating due to the circumstances. Lucci is caught flat-footed here and therefore we get a good idea of the distance he is sent when offering no resistance against the shockwave. We’ll need that for conservation of momentum.
Rob Lucci is 2.12 m tall. He’s 138 pixels here compared to the base diameter of shockwave at 76 and length at 53.
76 / 138 = .551 * 2.12 = 1.168 m, base diameter of shockwave
53 / 138 = .384 * 2.12 = .814 m, shockwave length
As I’ve established in previous blog entries, shockwaves have a tendency to dramatically increase in density over a short period of time. For this reason, just to be safe, I give them a density of 10 kg/m^3. That will apply here as well.
Treating the shockwave as a cone (which is the most common shape for a shock), the volume comes out to .291 m^3.
.291 * 10 = 2.91 Kg, weight of shockwave.
Luffy is 1.72 m tall here. He’s 48 pixels compared to distance Lucci was knocked at 400, as he was standing in front of Franky when he was hit.
400 / 48 = 8.333 * 1.72 = 14.333 m, distance Lucci traveled
With the projectile motion calculator, plugging in distance and an angle of 1 degree, his takeoff velocity would be 63.463 m/s.
Given his height of nearly 7 feet and his normally sleek, but strong build, I’ll assume a weight of 125 kg for Lucci.
Now, conservation of momentum…
2.91 * v = 125 * 63.463
2.91 * v = 7,932.875
v = 2,726.074 m/s, or Mach 8.02
Buster Call Test Firing
The marines test fire a Buster Call shot, creating a huge explosion at the fence of Enies Lobby. Was mostly curious at the firepower of a single shot from a warship, so thought this would be interesting to calculate.
Luffy, as previously established, is 1.72 m tall. He’s 15 pixels here compared to 145 for height of fence.
145 / 15 = 9.667 * 1.72 = 16.627 m, height of fence
The fence is 6 pixels compared to explosion diameter at 214.
214 / 6 = 35.667 * 16.627 = 593.035 m, diameter of explosion
From here we use the Taylor Formula.
E = 8*pi*p*R^5 / [75(y-1)t^2]
Where p is density of the air, t is time after explosion has formed, R is radius of the explosion. y is specific heat ration (Will be using 1.4 here as is common)
For time, I’ll be using the speed of the explosion. While there’s no evidence shockwave that propagates, the sheer size of the blast combined with the fact that this is military grade artilary makes me believe that it would be above the 177 m/s minimum. I’ll be going with 300 m/s.
593.035 / 2 = 296.518 m, radius of explosion.
296.518 / 300 = .989 s, time frame.
8 * 3.14 * 1.2 * 296.518^5 / [75(1.4 – 1).989^2] = 2,354,736,707,690.864 J, or 562.796 Tons of TNT
Luffy’s Gigant Pistol
Luffy’s Gear Third Gigant Pistol knocks Lucci through a wall and a full building before landing him on a marine warship. The resulting damage is a large building going down in addition to a hole in the wall.
Luffy, as previously established, is 1.72 m tall. He’s 58 pixels here compared to Lucci in Zoan form at 143.
143 / 58 = 2.466 * 1.72 = 4.241 m, Zoan Lucci height
Lucci is 31 pixels compared to Height of building destruction at 161, diameter of building destruction at 170, outer building wall thickness at 27, gigant pistol fist at 106 (This is for initial hole in the wall), and inner building wall thickness at 18.
161 / 31 = 5.194 * 4.241 = 22.028 m, height of building destruction
170 / 31 = 5.484 * 4.241 = 23.258 m, diameter of building destruction
27 / 31 = .871 * 4.241 = 3.694 m, outer building wall thickness
106 / 31 = 3.419 * 4.241 = 14.5 m, Gigant Pistol Fist/Hole in building wall
18 / 31 = .581 * 4.241 = 2.464 m, inner building wall thickness
Alright, so we need to treat that outside building as a hollow cylinder. To do this, I’ll find the regular cylinder volume, then subtract it by the volume of the cylinder not including the wall thickness to get the true volume of building destroyed.
Full cylinder volume = 9,358.574 m^3
3.694 * 2 = 7.388 m
23.258 – 7.388 = 15.87 m, inner diameter.
Volume for the “inner” cylinder is 4,357.314 m^3
9,358.574 – 4,357.314 = 5,001.26 m^3, volume of outer building destroyed.
Treating the hole of the inner building as a cylinder with a diameter of Luffy’s giant fist, the volume comes to 406.88 m^3.
5,001.26 + 406.88 = 5,408.14 m^3, total stone destroyed
I see both vapor and debris in the scans, so I’ll go with cratering, 87 J/cc.
5,408.14 m^3 = 5,408,140,000 cm^3
5,408,140,000 * 87 = 470,508,180,000 J, or 112.454 Tons of TNT
Rob Lucci’s Rankyaku Gaichou
Lucci’s Rankyaku Gaichou cuts through the steel deck of a warship.
Luffy is 1.72 m (Obviously) and he measures 7 pixels here compared to the cannon window at 25.
25 / 7 = 3.571 * 1.72 = 6.142 m, cannon window width
The cannon window is 44 pixels wide compared to cut steel height at 205, and cut width at 93.
205 / 44 = 4.66 * 6.142 = 28.622 m, cut steel height
93 / 44 = 2.114 * 6.142 = 12.984 m, cut steel width
Cut steel width is 39 pixels compared to cut length at 26.
26 / 39 = .667 * 12.984 = 8.66 m, steel cut length
As a triangular prism, the volume of cut steel comes out to 1,064.984 m^3
As previously established, cutting steel requires vaporization for quick and practical use.
Density of Steel is 7,850 Kg/m^3.
7,850 * 1,064.984 = 8,360,124.4 Kg, weight of cut steel
Boiling point of steel is 2750 C. I’ll assume the conversion is from room temp to 2750, so 2720 C is our number. Specific heat of steel is 490 J/kg C. Total weight is 8,360,124.4 Kg.
8,360,124.4 * 490 * 2720 = 11,142,373,800,320 J
Now we need to find latent heat of vaporization. I can’t seem to find this figure for steel, so I’m using iron, which is a big part of steel anyway so I don’t think it’s unreasonable. Iron has a latent heat for vaporization of 6,090 kj/kg
8,360,124.4 * 6,090,000 = 50,913,157,596,000 J
50,913,157,596,000 + 11,142,373,800,320 = 62,055,531,396,320 J, or 14.83 Kilotons
That’s like a Hiroshima bomb in cutting form! Well above any other feat this arc. Does it reach outlier territory? Well, that’s for you to decide as always. To cut through as much steel as Lucci did would take an insane amount of power. Believe it or not, I had originally calculated this to be nearly 80 Kilotons, but then I realized that the other part of the boat he cut was clearly made of wood. lol
