Introduction[]
In Akame Ga Kill, Esdeath freezes a lake. I'll be calculating the yield of this feat.
Calculation[]
Just saying it right now, this calc will be lowballed because I'm not accounting for the icicles. That is way too much work for me to handle.
Average Window Height = 1.5 meters = 2 px
1.5 / 2 = 0.75 meters per px
Lake Width = 121.25 px = 90.94 meters
Screen Height = 648 px
Lake Length = (1.5 * 648) / [2 * 2tan(70/2 deg)] = 347.04 meters
Average Lake Depth = 42 meters
Lake Volume = 347.04 * 90.94 * 42 = 1325512.34 meters^3
Density of Water = 1000 kg/meters^3
Lake Mass = 1325512.34 * 1000 = 1325512340 kg
Specific Heat Capacity of Water = 4186 J/kg
Average Lake Temperature = 17 degrees Celsius
Freezing Point of Water = 0 degrees Celsius
Change in Temperature = 17 - 0 = 17 degrees Celsius
Q1 = MC(delta)T = 1325512340 * 4186 * 17 = 9.43261091e+13 Joules
Latent Heat of Fusion = 334000 Joules/kg
Q2 = Mass * Latent Heat of Fusion = 1325512340 * 334000 = 4.42721122e+14 Joules
Q = Q1 + Q2 = 9.43261091e+13 + 4.42721122e+14 = 5.37047231e+14 Joules
Final Result[]
Esdeath Freezes a Lake = 128.36 kilotons; Large Town level (High 7-C)
Good for a casual feat I guess.
