A similar analysis of sound pressure level in dB would be interesting. SPL has no meaning at STP at about 170dB, as longitudinal compression waves turns into a shock wave, microns thick. But it would be interesting to see how loud it was around the globe as a function of time.
@@Kaldisti Though, strong shock waves move faster than the speed of sound, and the speed of sound would also be substantially higher in the air that has been heated due to the thermal radiation effects. For example, in air (with an adiabatic exponent of 1.4), a shock with an overpressure of 3.5 bar (pressure ratio across the shock of 4.5) should be moving at Mach 2
@@Kaldisti I don't know if youtube would like me posting links, but look up "Normal shock tables" on wikipedia. That has the relevant equations (which would be pretty messy to write out in normal text like this), as well as a pre-calculated table for shock velocities up to Mach 5 in air.

i really love your videos dude

Cool but wouldnt the initial blast at
it would be 1 kilometer wide
Why is the shockwave so slow? Would it just fizzle out at such a slow speed?
sound speed bro
@Kaldisti Oh okay. Thank you.

@@zuthalsoraniz6764 thanks, could you please provide me the equations to calculate velocities properly ? it will improve future impact simulations :)

How huge would be fireball and how high it would be?
as big as it is wide
I dont think 316 m is 30k feet
who said that
