**Scaling**

Fujiko's head = 8 pixels (Black Line) = 0.20875 m

Airplane's length = 222 pixels (White Line) = 0.20875*(222/8) = 5.7928125 m

Airplane's length = 48 pixels (Red Line) = 5.7928125 m

Waterspout's width (Base) = 35 pixels (Blue Line) = 5.7928125*(35/48) = 4.22392578 m

Waterspout's width (Base) = 8 pixels (Grey Line) = 4.22392578 m

Waterspout's height (Base) = 47 pixels (Yellow Line) = 4.22392578*(47/8) = 24.815564 m

Waterspout's width (P1) = 10 pixels (White Line) = 4.22392578*(10/8) = 5.27990723 m

Waterspout's height (P1) = 58 pixels (Red Line) = 4.22392578*(58/8) = 30.6234619 m

Waterspout's width (P2) = 16 pixels (Green Line) = 4.22392578*(16/8) = 8.44785156 m

Waterspout's height (P3) = 52 pixels (Brown Line) = 4.22392578*(52/8) = 27.4555176 m

Waterspout's width (P4) = 30 pixels (Blue Line) = 4.22392578*(30/8) = 15.8397217 m

Waterspout's height (P4) = 47 pixels (Turquoise Line) = 4.22392578*(47/8) = 24.815564 m

Waterspout's width (P5) = 42 pixels (Purple Line) = 4.22392578*(42/8) = 22.1756103 m

Waterspout's height (P4) = 2000-(24.815564+30.6234619+13.1997681+27.4555176+24.815564) = 1879.090124 m

Since we don't see the peak of the tornado and it was show that the tornadoes/waterspouts generate by Columbus's Egg can reach a height of 2000 meters (as it is show in the scans below), i think is fair to assume that the waterspout would be about 2 km in height.

**Calculations**

Waterspouts and tornadoes are very similar, so i think it should be fair to use the same formula of Flashlight237.

Volume (Base) = pi*(4.22392578/2)^2*24.815564 = 347.733545 m^3

Volume (P1) = pi*(5.27990723/2)^2*30.6234619 = 670.496863 m^3

Volume (P2) = pi*(8.44785156/2)^2*13.1997681 = 739.858608 m^3

Volume (P3) = pi*(10.0318237/2)^2*27.4555176 = 2170.09776 m^3

Volume (P4) = pi*(15.8397217/2)^2*24.815564 = 4890.003 m^3

Volume (P5) = pi*(22.1756103/2)^2*1879.090124 = 725752.689 m^3

Total Volume = 347.733545+670.496863+739.858608+2170.09776+4890.003+725752.689 = 734570.879 m^3

~~Density (Tornado) = 1.184 kg/m^3~~

As TheRustyOne suggested, the waterspout seen to be also made up in part by water from the ocean which had be raised and collected by the winds, and while this isn't normal for a tornado/waterspout, it must be remember that this isn't a natural occurance, the waterspout was created artificially with Columbus's Egg, so i think it make to assume that the waterspout isn't made of just air and it also made by water, even if its just of 1%.

Density (Sea Water) = 1020 kg/m^3

Mass = 734570.879*1020 = 749262297*1% = 7492622.97 kg

For the speed, its hard to determinate precisely, however it was show that the tornados/waterspouts created by Columbus's Egg can be generate in a matter of seconds (with a heights of 2 kilometers) and possess wind speeds powerful enough to easily affect the surrouding water, lift people up to the air for dozens of (if not hundreds of) meters and even destroy military jets.

So we are dealing with speed far above the usual, but since i don't have a good way to calculate the precise number, i will calc all results by use the entire EF ratings, leaving to the Calculation Group the choice of which end use.

Speed (EF0) = 65-85 mph or 29.0576 to 37.9984 m/s

Speed (EF1) = 86-110 mph or 38.44544 to 49.1744 m/s

Speed (EF2) = 111-135 mph or 49.62144 to 60.3504 m/s

Speed (EF3) = 136-165 mph or 60.79744 to 73.7616 m/s

Speed (EF4) = 166-200 mph or 74.20864 to 89.40800 m/s

Speed (EF5) = 200+ mph or 89.40800+ m/s

KE (EF0) = 1/2*7492622.97*(29.0576)^2 = 3.16317607e9 Joules or 0.756017224 Tons of TNT

KE (EF1) = 1/2*7492622.97*(38.44544)^2 = 5.53724266e9 Joules or 1.32343276 Tons of TNT

KE (EF2) = 1/2*7492622.97*(49.62144)^2 = 9.22449523e9 Joules or 2.20470727 Tons of TNT

KE (EF3) = 1/2*7492622.97*(60.79744)^2 = 1.38475987e10 Joules or 3.30965553 Tons of TNT

KE (EF4) = 1/2*7492622.97*(74.20864)^2 = 2.06306461e10 Joules or 4.93084276 Tons of TNT

KE (EF5) = 1/2*7492622.97*(89.40800)^2 = 2.9947229e10 Joules or 7.15755953 Tons of TNT

**Results**

KE (EF0) = 0.756 Tons of TNT = **Building level**

KE (EF1) = 1.323 Tons of TNT = **Building level+**

KE (EF2) = 2.204 Tons of TNT = **Large Building level (Accepted)**

KE (EF3) = 3.309 Tons of TNT = **Large Building level**

KE (EF4) = 4.93 Tons of TNT = **Large Building level**

KE (EF5) = 7.157 Tons of TNT = **Large Building level+**

~~That's... seen really underwhelming, considering that even a type F0 Tornado is can generate 2.1793 Tons of TNT, so i do have the feeling that it is a massive lowball, if not an actual downplay. ~~

~~Considering that if i consider other scenes the waterspout seen to be way bigger than the result i got, and that it was also powerful enough to moving the surrounding water around itself. ~~

~~If anyone had any suggestions a better way to calc the feat, if what i think is correct, you're welcome.~~
