After the 60 Minute War, multiple Slow Bombs hit the Earth, one of which destroys Panama, seperating North and South America. A quick search reveals that Panama has a surface area of 75,517 km^2, or 75517000000m^2. It also has an average elevation of 360m.
V = Ah
= 75517000000 X 360
For a low end we'll go with violent fragmentation (69000000 joules/m^3) and for a high end pulverization (200000000 joules/m^3).
E = 2.718612e13 X 69000000
= 1.8758422800000001e+21 joules
= 448.33706500956026275 gigatons
E = 2.718612e13 X 200000000
= 5.437224e21 joules
= 1.2995277246653920145 teratons
Slow Bomb destroys Panama (low end) = 448.337 gigatons
Slow Bomb destroys Panama (high end) = 1.29 teratons
Jupiter in the Larklight universe is 3218688000m in diameter and weighs 2.31529493e31kg according to my previous calculations. That means it has a gravity acceleration of 149.15055558962194m/s^2 according to this calculator. We can scale from the illustrations.
R = (h/2) + c^2/(8h)
= (44/2) + 690^2/(8 X 44)
D = 1374.55682 X 2
2749.11364 pixels = 3218688000m
1 pixel = 3218688000m/2749.11364 = 1170809.37m
The top part of each as an ellipsoid, the rest as cylinders
1356297.25m X 196 = 265834261m
265834261m/2 = 132917130m
1356297.25m X 98 = 132917130m
132917130m/2 = 66458565m
1356297.25m X 270 = 366200258m
1356297.25m X 200 = 271259450m
366200258m + 271259450m = 637459708m
1356297.25m X 45 = 61033376.2m
61033376.2m/2 = 30516688.1m
366200258m + 271259450m + 265834261m = 903293969m
V = 4/3πabc
= 4/3 X π X 132917130 X 66458565 X 66458565
On the atmosphere of Jupiter;
M = 2.45907335e24 X 0.0899
V = πr^2h
= π X 61033376.2^2 X 637459708
M = 7.4599755e24 X 0.0899
M = 2.21070694e23kg + 6.70651797e23kg
E = 8.91722491e23 X 149.15055558962194 X 903293969
= 1.20138915e35 joules
= 28.7138898184 yottatons
Now onto the other storms.
1356297.25m X 238 = 322798746m
322798746m/2 = 161399373m
1356297.25m X 141 = 191237912m

1356297.25m X 124 = 168180859m
310592070m + 111216374m = 421808444m
1356297.25m X 82 = 111216374m
111216374m/2 = 55608187m
322798746m + 310592070m + 111216374m = 744607190m
V = 4/3πabc
= 4/3 X π X 161399373 X 95618956 X 95618956
M = 6.18128044e24 X 0.0899

= 1.02627278e35 joules
= 24.5285081262 yottatons
Now for the final storm on the left.
1356297.25m X 149 = 202088290m
202088290m/2 = 101044145m
1356297.25m X 114 = 154617886m
154617886m/2 = 77308943m
1356297.25m X 96 = 130204536m
130204536m/2 = 65102268m
1356297.25m X 205 = 278040936m
1356297.25m X 131 = 177674940m
278040936m + 177674940m = 455715876m
1356297.25m X 133 = 180387534m
278040936m + 177674940m + 180387534m = 636103410m
V = 4/3πabc
= 4/3 X π X 101044145 X 77308943 X 77308943
M = 2.52964299e24 X 0.0899

E = 7.72916419e23 X 149.15055558962194 X 636103410
= 7.33305821e34 joules
= 17.5264297562 yottatons
So each storm (or arm of Thunderhead) is large planet level+. Damn! How much energy is all of that together?
E = 28.7138898184 yottatons + 24.5285081262 yottatons + 17.5264297562 yottatons
= 70.7688277 yottatons
Storms attack Snilth fleet = >70.769 yottatons
And that's not even taking kinetic energy into account! Also for reference, this is part of the Larklight trilogy.
The Scrivener Institute's durability = 50 megatons
Do we have scaling from the books to help say how tall? Thankfully, yes.
124/2 = 62 pixels
62 pixels = 91.44m
1 pixel = 91.44m/62 = 1.47483871m
1.47483871m X 124 = 182.88m
1.47483871m X 233 = 343.637419m
343.637419m/2 = 171.81871m
1.47483871m X 55 = 81.116129m
81.116129m/2 = 40.5580645m
The first quote says conical, while the next says bowl-like. I'll calc it as a conical frustrum.
V = (1/3)π(r^2+rR+R^2)h
= (1/3) X π X (40.5580645^2 + 40.5580645 X 171.81871 + 171.81871^2) X 182.88
The craters hollow, so it would have needed to eject all the stone from inside it. So violent fragmentation it is.
E = 7303340.4 X 69000000
= 5.03930488e14 joules
= 120.442277247 kilotons
And that's not taking into account the underwater parts, so ultimately it would be even higher.
Mayda's crater formation = >120.442 kilotons
Mortal Engines is a world where cities wander around and eat each other for reference. First up is an easy one; Salthooks speed.
Salthook flees London = 35.75m/s
London's kinetic energy = 100.422 tons of TNT
V = (π X 91.44^2/3) X (3 X 1609344 - 91.44)
The average weight of Mars per m^3 is 3933kg.
M = 4.227299e10 X 3933
Escape velocity of Mars is 5.03km/s, or 5030m/s.
E = (0.5) X 1.6625967e14 X 5030^2
= 2.10325964e21 joules
= 502.691118547 gigatons
Larklight's gravity engines explode = >502.691 gigatons
Starcross is alot bigger than that, so this is very much a low end.
T = 16093.44km/10h
= Mach 1.31370302
T = 16093.44km/6h
= Mach 2.18950503
T = 16093.44km/3h
= Mach 4.37901005
Train travels to Starcross (low end) = Mach 1.314
Train travels to Starcross (mid end) = Mach 2.19
Train travels to Starcross (high end) = Mach 4.379
We've had a lot of Jupiter calcs recently, haven't we?
V = 4/3πabc
= 4/3 X π X 16000 X 6500 X 160.9344
Density of a cloud is 1.003kg/m^3.However, on Jupiter everything weighs 2.4 times more.
M = 7.01085256e+19 X 1.003
= 7.03188512e19 X 2.4
The energy to condense clouds is 2,500,000 joules per kg.
E = 1.68765243e20 X 2,500,000
= 4.21913107e26 joules
That's not all; we can also find the energy of the storms rotations.
E = (0.5) X 1.68765243e20 X 171.66336^2
= 2.48661318e24 joules
Now our total energy!
E = 4.21913107e26 + 2.48661318e24
= 101.433967495 petatons
Thunderheads general power = 101.439 petatons
I feel this isn't quite right, so help on this would be appreciated.
T = 628,300,000km/10h
= Mach 51287.9538
T = 628,300,000km/6h
= Mach 85479.923
T = 628,300,000km/3h
= Mach 170959.846
The Uncrushable flies to Jupiter (low end) = Mach 51287.954
The Uncrushable flies to Jupiter (mid end) = Mach 85479.923
The Uncrushable flies to Jupiter (high end) = Mach 170959.846
V = 4/3πr^3
= 4/3 X π X 1737^3
Hydrogen weighs 0.0899^2kg per m^3.
M = 2.19527062e+19 X 0.0899^2
The heat of combustion of hydrogen is 144000 kilojoules/kg.
E = 1.77421991e17 X 144000
= 2.55487667e22 kilojoules
= 6.10630179254 petatons
Thunderhead creates moon-sized fires = 6.106 petatons
T = 48280.32km/10s
= Mach 14187.9926
T = 48280.32km/3s
= Mach 47293.3086
Larklight flies to Earth (low end) = Mach 14187.993
Larklight flies to Earth (high end) = Mach 47293.309
And the power of it's gravity engines risked tearing the Moon apart just by flying by.
M2 = (H2/H1)^3*M1
= (3218688000/139822000)^3 X 1.89800e27
This is the formula for finding the GBE of a planet;
U = GBE
G = gravitational constant
M = mass
r = radius
The gravitational constant is 6.67408e-11m^3/kg per s.
U = (3) X (6.67408e-11) X (2.31529493e31^2)/(5 X 1,609,344,000)
= 1.33384822e43 joules
= 3.18797375717 tenakilotons
Lantern of Creations Dawn shapes the solar system = >3.188 tenakilotons
The hype is so damn real right now!
No not that Shrike, the one from Mortal Engines. During a chase early in the series, Shrike is ran over by a small traction town.
So how fast do Traction Towns move?
Here's a picture of Turnbridge Wheels from the Traction Codex.
At an estimate, the town that ran over Mr Shrike is about the size of a super yacht, Turnbridge Wheels itself would be even bigger going by that above image.
Weight = 13,000 tons
Speed = 80 miles
Energy = 1.987 tons of TNT
Weight = 15,850 tons
Speed = 80 miles
Energy = 2.4226 tons of TNT
Weight = 20,000 tons
Speed = 80 miles
Energy = 3.0569 tons of TNT
He then gets up like none of that shit even happeneed and keeps going about his business.
