Did some Batman calcs on the fly in a thread, I'll move them here. Using a ruler, 40 minutes of my time before I went to bed without the computer and that's it. So a potential mistake and or margin of error is possible, since I wasn't using pixel scaling.
Average human leg is 35 inches = 0.889 meters long
Leg = 0.2 cm
Explosion = 5 cm
5/0.2 = 25 * 0.889
Diameter = 22.225 Meters
Radius = 11.1125 Meters
(11.1125)^3*((27136*1.37895 + 8649)^(1/2)/13568 - 93/13568)^2
0.1103 Tons of TNT (Batman's bomb) or Small Building level
Average car width is 6.5 feet = 0.4 Cm
Explosion = 4.5 cm
4.5/0.4 = 11.125 * 6.5
Diameter = 72.3125 Feet = 22.04085 Meters
Radius = 11.020425 Meters
(11.020425)^3*((27136*1.37895 + 8649)^(1/2)/13568 - 93/13568)^2
0.1075674 Tons of TNT or Small Building level
(I think this one was close enough to Batman to where inverse law doesn't need to apply)
Explosion = 3.2 cm
Average train height = 9 feet and 2 inches (9.1667 feet)
Train height = 0.7 cm
3.2/0.7 = 4.57143 * 9.1667
Diameter Explosion = 41.90492 Feet = 12.77262 Meters
Radius = 6.38731 Meters
(6.38731)^3*((27136*1.37895 + 8649)^(1/2)/13568 - 93/13568)^2
0.020943 Tons of TNT or Small Building level
Average Human head = 0.239 Meters
Batman's head = 0.1 cm
Explosion length = 11.7 cm
11.7/0.1 = 117 * 0.239
Explosion Diameter = 27.963 Meters
Explosion Radius = 13.9815 Meters
(13.9815)^3*((27136*1.37895 + 8649)^(1/2)/13568 - 93/13568)^2
0.2196579 Tons of TNT or Small Building level+
Alrighty then assuming KE, since there’s a big rubble cloud.
Flash stated he was going 10 times his previous speed, which was speed of sound.
Flash weights 88 Kg
0.5*88*3430*2
517655600 Joules
0.123722657744 Tons of TNT or Small Building level
