## Piplup creates a whirlpool

### The Feat

This occurs in Season 10, episode DP39.

In order to create a gap between a steamboat and a waterfall, Dawn’s Piplup creates a large whirlpool by throwing his own against the water.

### Water Mass

• Green Line = Whirlpool’s Radius = 1080 px = 475.667484793 meters

Using the semi sphere formula:

• V = (4/3)*π*R^3
• V = (4/3)*π*475.667484793^3
• V = 450587127.76 m^3

Density of water is 1000 kg/m^3

• M = Density * Volume
• M = 1000 * 450587127.76
• M = 450587127760 kg

### KEr

I’ll use the Rotational Kinetic Energy Formula, so I need to find the rotation velocity.

• ω = θ/t
• ω = Revolutions/Minute

According to Bulbapedia, DP series runs at 30 FPS and using Premiere, it took that amount of frames for another ring to appear in the whirlpool.

• ω = 60/1 = 60 Rads per minute or 1 Rad/s

Rotational Kinetic Energy Formula:

• KE = 0.5 I ω^2
• I = Angular moment of inertia = 0.5 m r^2
```* m = Mass
```
```* r = Radius
```
• ω = Angular speed
• I = 0.5*450587127760*475.667484793^2 = 225293563880*226259.556089 = 5.0974822e+16 kg m^2

KE = 0.5 I ω2 = 0.5*5.0974822e+16*1^2 = 2.5487411e+16 joules, 6.091637428298279 megatons or Small City Level+

So, either I’m doing something seriously wrong here or this is an Outlier. Both are very likely.

## Mantyke carries a Boulder

### The Feat

This occurs in Season 12, DP112

I guess this time the name is self explanatory.

### Mass

• Green Line = Mantyke height = 526 px = 1 meter
• Red Line = Mantyke’s back’s smile = 182 px = 0.34600760376 meters
• Red Line = Mantyke’s back’s smile = 64 px = 0.34600760376 meters
• Pink Line = Boulder lower(1)/upper(2) length = 559 px = 3.0221601592 meters
• Yellow Line = Boulder Height (1) = 671 px = 3.6276734648 meters
• Blue Line = Boulder Height (2) = 112 px = 0.6055133056 meters
• Purple Line = Boulder upper length (1) = 170 px = 0.919082696 meters
• Orange Line = Boulder lower length (2) = 329 px = 1.7786953352 meters

Assuming the boulder is a truncated cone:

• V1 = 12.11445385289 m^3
• V2 = 2.8015314381489 m^3
• V1 + V2 = 12.11445385289 + 2.8015314381489 = 14.915985291 m^3

Given that this boulder is later stated to be a meteor, which density rangse from 3000-3700 kg/m^3, I’ll use it’s average (3350 kg/m^3)

• M = Density * Volume
• M = 3350 * 14.915985291
• M = 49968.5507248 kg

Dividing by 3 = 16656.1835749 kg or Class 25 for each Mantyke. Likely higher as there are chunks that aren’t covered and the Mantykes are doing this rather casually.

## Gible lifts a Boulder

### The Feat

This occurs in Season 12, episode DP145.

In order to show his endurance, Gible lifts a boulder using strength to let it fall and break over his head.

### Mass

• Blue Line = Boulder length = 1322 px = 5.78375 meters
• Boulder Radius = 5.78375/2 = 2.891875 meters
• Red Line = Boulder Width = 1055 px = 4.615625 meters

In order to find the volume, I’ll use an ellipsoid.

• V = 4/3*π*a*b*c
• V = 4/3*π*2.891875*4.615625*4.615625
• V = 258.065031298 m^3

Density of rock is 2700 kg/m^3.

• M = Density * Volume
• M = 2700 * 258.065031298
