User blog:ThePerpetual/Request 1: (insert icicle related pun)

So, here's a request for a calc from one Spinoirr.

I can, for starters, at least find a volume (roughly) for the parallelogram prism affected by this attack.

5'2" = 157.4 centimeters First Pic: 157.4 cm/277 px = 0.57 cm/px, *1385 px = Width: 789.45 cm. Or,

Width: 7.89 m

Second Pic: 157.4 cm/86 px = 1.83 cm/px, *445 px = Height: 814.35 cm. Or, Height: 8.14 m And 1.83 cm/px, *1559 px = Length: 2852.97 cm. Or, Length: 28.53 m

So, total volume:

(7.89 * 8.14 * 28.53) = 1832.33 cubic meters.

With the density of air being 1.225 kg/cubic meter, that means-

Total Mass = 2244.6 kg

For the energy required to actually freeze this air, now, I've found a nifty collection of values that'll help with this in the form of [| some BnHA calcs] I've found. More specifically, resources demonstrating that air mostly (~80%) nitrogen, and effectively 20% oxygen. I also have the Latent Heats for Fusion and Vaporization, so... let's get to it.

Mass of Nitrogen: 1795.7 kg Mass of Oxygen: 448.9 kg

Specific Heat of Nitrogen: 1040 J/kg.K Latent Heat of Fusion (Nitrogen): 25702 J/kg Latent Heat of Vaporization (Nitrogen): 199190 J/kg Freezing Point: -210.1° Celsius
 * ΔT: (23 - (-210.1)) = 233.1

Assuming 23 degrees Celsius [room temperature], anyways, for starting temperature.

(1795.7 kg x 1040 J/kg.K x 233.1 ΔT) + (1795.7 kg x (25702 + 199190)) = 839159341.2 Joules

And now, for the oxygen-

Specific Heat of Nitrogen: 919 J/kg.K Latent Heat of Fusion (Nitrogen): 13875 J/kg Latent Heat of Vaporization (Nitrogen): 213125 J/kg Freezing Point: -218.3° Celsius
 * ΔT: (23 - (-218.3)) = 241.3

(448.9 kg x 919 J/kg.K x 233.1 ΔT) + (448.9 kg x (13875 + 213125)) = 198063164.2 Joules

Add these together, for the final yield:

839159341.2 J + 198063164.2 J = 1.0372e+9 Joules, or 0.248 Tons of TNT.

Or, the very, very highest end of Small Building level+. So close, in fact, to breaching the gap, that I: considering that I rounded down the mass frozen with this attack by not taking into account the caps on the ice spikes on the top of the attack: would round this up to Building level (0.25-2 Tons of TNT.) Also, if this was at all not the character's full power? Like... one would need ~0.8% more to hit that 8-C point. That's all I'll say on this...

Final Tally
Freezing Wave: 0.248+ Tons of TNT
