During the fight with Lokkestiiz, he summons storm atronachs and frost atronachs. Upon defeating the storm atronachs they leave a circle of electricity, which can then be used to vaporize the frost atronachs by getting them to walk into them. The average height of a woman is 5 feet 3 inches, or 1.6002m.Elsweyr Online said:
564 + 230 = 794 pixels
1 pixel = 1.6002m/326 = 0.00490858896m
0.00490858896m X 794 = 3.89741963m
Next to determine the mass of the ice atronach using inverse square law. The average height of a man is 171cm (or 1.71m) and the average weight of a man is 177.5kg (in North America, but given the bulkiness of the ice atronachs this is still likely a lowball).
M2 = (H2/H1)^3*M1
= (3.89741963/1.71)^3*177.5
= 2101.55873kg
But that's not all; now we switch the mass of flesh for that of ice. The average mass of flesh per m^3 is 1010kg, and the average mass of ice is 919kg per m^3.
M = 2101.55873/1010 X 919
= 1912.21037kg
= 1912210.37g
Specific heat of water is 4.186 joules per gram.
E = 1912210.37 X 4.186
= 8004512.61
Next we'll add the heat fusion of water, which is 334 kilojoules per kg.
E = 1912.21037 X 334
= 638678.264 kilojoules
= 638678264 joules
Next, the energy with which to vaporize water, the values of which can be found here.
E = 1912.21037 X 2.26 X 10^6
= 4.32159544e9 joules
Finally, let's add everything together.
E = 8004512.61 + 638678264 + 4.32159544e9
= 4.96827822e9 joules
= 1.187446993308 tons of TNT
Final Results
Ice Atronach melts = 1.187 tons of TNT
I've a feeling I may have messed something up in there. :thunk Still, there you go.
