In chapter 8 of Neon Cavaliers, Connor in his Phoenix Form turns a large tsunami to vapor and I'll be calculating the feat to see what AP it would get.
According to this a tidal wave contains 22,500 gallons of water or 85171.7651 kg of water. The largest waved surfed is 73.5 feet which I'll be using for the 22,500 gallons of water to get a rough estimate of the tsunami. The largest tsunami ever is the Lituya Bay Mega Tsunami which was 1,700 feet.
Tsunami height difference: 1,700/73.5= 23.1292517
Amount of water: 85171.7651x23.1292517= 1969959.19 kg
It takes 100 degrees for water to boil so now we need to multiply 100 degrees by 2575 J (Vaporization of water), per each kilogram.
100x2575= 257500
257500x1969959.19= 507,264,491,425
Now we need to multiply 2575 J by the amount of kilograms of water.
507,264,491,425x2575= 1.30620607e15
Now add them together.
1.30620607e15+507,264,491,425= 1.30671333e15 J (High 7-C or Large Town)
Now since Connor was in his Phoenix Form we divide 1.30671333e15 by 20 to get his base power.
1.30671333e15/20= 6.53356665e13 J (7-C or Town level)
I'm certain I did this wrong.
