Introduction[]
In One-Punch Man, Withered Sprout creates a large formation of ice. I'll be calculating his attack potency.
Calculation[]
Smile Man's head (Average) = 177 / 8 = 0.22125 cm
Base Ice = 3.88 m
Base Ice Radius = 1.94 m
Ice Height = 8.90 m
We put these values on this Cone Calculator to get the volume.
Volume = 35.08 m^3
Now I can find the freezing energy of this feat.
Air is 80% nitrogen and 20% oxygen.
Frozen nitrogen density is 1026.5 kg/m^3.
Density of solid oxygen is 1426 kg/m^3.
NM = 35.08 x 1026.5 x 0.8 = 28807.696 kg
OM = 35.08 x 1426.5 x 0.2 = 10008.324 kg
Freezing Energy
NM = 28807.696 kg
Nitrogen specific heat is 1040 j/kg, air temperature is 293 degrees kelvin, boiling point of nitrogen is 77.36 K.
NQ = 28807.696 x 1040 x (293-77.36) = 6460575228.0576 Joules
Nitrogen vaporization is 199000 j/kg.
NV = 28807.696 x 199000 = 5732731504 Joules
Melting temperature of nitrogen is 63.15 kelvin.
NQ = 28807.696 x 1040 x (77.36-63.15) = 425731654.5664 Joules
Fusion of nitrogen is 25800 j/kg
NF = 28807.696 x 25800 = 743238556.8 Joules
Nitrogen Freezing Energy = 6460575228.0576 + 5732731504 + 425731654.5664 + 743238556.8 = 13362276943.424 Joules
OM = 10008.324 kg
Oxygen specific heat is 918 j/kgk, air temperature is 293 degrees kelvin, boiling temperature of oxygen is 90.2 kelvin.
OQ = 10008.324 x 918 x (293-90.2) = 1863253682.4096 Joules
Heat of vaporization of oxygen is 214000 j/kg.
OV = 10008.324 x 214000 = 2141781336 Joules
Melting temperature of oxygen is 54.75 kelvin.
OQ = 10008.324 x 918 x (90.2-54.75) = 325701888.7644 Joules
Fusion energy of oxygen is 13875 j/kg.
OS = 10008.324 x 13875 = 138865495.5 Joules
Oxygen Freezing Energy = 1863253682.4096 + 2141781336 + 325701888.7644 + 138865495.5 = 4469602402.674 Joules
Total Energy = 13362276943.424 + 4469602402.674 = 17831879346.098 Joules
Final Tally[]
Withered Sprout's Attack Potency = 4.26 Tons of TNT (Large Building level)
