Context[]
Shiroko has an EX Skill in which she is able to dispel of a storm and bring about a sunny day. This seems pretty simple as it's a basic cloud feat and thus It would be in our interests to calculate how much it yields
The Feat[]
When determining the cloud volume, the most reliable method is going off of the viewing distance and using base area formula.
The standard value is 20 km (20,000 meters) as far as viewing distance goes and given how violent the storm is and the darkness of the clouds, this would mean that the clouds are cumulonimbus clouds
- Cumulonimbus clouds can range between 8000m to 11800m (the average of this would be 9900m)
So now that we got that all figured out, we can finally get to doing the calculations that are needed to figure out the mass
- Cloud Volume: pi x 20000^2 x 9900 = 1.2440707e+13
- Density of Air: 1.003 kg/meters^3
- Cloud Mass: 1.2440707e+13 * 1.003 = 1.2478029e+13 kg
So this would mean that the volume of the cloud is 1.2478029e+13 kilograms but we still aren't done as we also need to find the speed in which she parted the clouds Going off of the video, we can see that Shiroko parts the sky in a single second and thus this would mean she parted them away at 20,000 m/s Given the nature of this feat, we can also use kinetic energy as well
- 0.5 x 1.2478029e+13 x 20000^2 = 2.4956058e+21 Joules
So with all of that in mind, this means Shiroko's feat would yield Large Island Level results (High 6-C; 596 Gigatons)
