In my last calculation regarding the power bomb, I ended up with a yield of 376.76 tons of TNT, but what I failed to do here is consider that this explosion goes farther than a 30 m. radius. While Room MW is 30 m. long, moving towards one end of the room and using a power bomb will show that half of this power bomb can still reach half of the room’s length, which is 15 m. Multiply this by 2 and you end up with 30 m. Add that with the 30 m. room itself and you end up with 60 m. I’ll use the equation from the late G. I. Taylor again and assume we’re using TNT, since that’s a common explosive in the military. TNT has a detonation velocity of 6,900 m/s, so it’ll take 8.69 milliseconds for it to cover 60 m. The energy would be 12,597,606,000,000.11 J, which is equal to 3.01 kilotons of TNT.
