Calc Kill La Kill - Ryuko causes water explosion

(Episode 21)


Mako and Senketsu purge Ryuko of Junketsu's influence, and this causes a huge water explosion. Scaling from the S. S. Naked Sun. The standard height of a door is 6 feet 8 inches (or 2.03200m)
161 pixels = 2.03200m
1 pixel = 2.03200m/161 = 0.012621118m
0.012621118m X 735 = 9.27652173m
18 pixels = 9.27652173m
1 pixel = 9.27652173m/18 = 0.515362318m
0.515362318m X 224 = 115.441159m
0.515362318m X 999 = 514.846956m
0.515362318m X 1900 = 979.188404m
979.188404m/2 = 489.594202m
0.515362318m X 1489 = 767.374492m
767.374492m/2 = 383.687246m
0.515362318m X 1387 = 714.807535m

Volume as the bottom parts and top parts as cylinders.

V = πr^2h
= π X 489.594202^2 X 115.441159
= 86932682.9m^3

V = πr^2h
= π X 383.687246^2 X 514.846956
= 238112804m^3

V = 86932682.9 + 238112804
= 325045487m^3

Weight of water is 1000kg/m^3.

M = 325045487 X 1000
= 325045487000kg
Now for the timeframe.
0.6 seconds.

T = 714.807535m/0.6s
= 1191.34589m/s

Finally, for our energy.

KE = (0.5)mv^2
= (0.5) X 325045487000 X 1191.34589^2
= 2.30669347e17 joules
= 55.131297084130018504 megatons

Final Results
Ryuko gets purged = 55.131 megatons
