Explosion yield formula under different pressures?

[Rodri_"Dante"]

So we have two formulas for explosion yields: One for mid-air explosions and one for explosions against a surface.

The later allows to change the pressure (In case, you know, the explosion happens underwater or in a vacuum), but the former doesn't.

I feel like this should be fixed.

I'm not a calc group member, but I'll try to answer based on my experience with this.

Underwater explosions would fall under ground level I believe, since it's at or below ground level. Air blast explosions are, as the name implies, strictly in the air. As for vacuums, aerial explosions cannot occur in a vacuum. If it's depicted as happening, it can't be calculated that way because there's no air to begin with. In that case, you'd be better of trying to calculate it another way.

Example: If there's debris that's launched from the explosion, you can get the mass of it and the speed it was launched at and calc the explosion via the kinetic energy that the debris was dispersed at.

Basically, aerial explosions are strictly in the air and not in a vacuum or underwater, so there'd only be one pressure instead of the ability for there to be multiple possible pressures. Hope this helps.

Guess that makes sense, but it doesn't cover explosions happening mid-air under different pressures (Like over a mountain or in the moon)

My guess is that its effect on the yield is basically negligible for aerial explosions but not negligible for ground-level explosions.

You can't use any of the explosion formulae if said explosion happens in outer space, since, well, no pressure. Explosions in outer space are limited to sheer KE.

There IS "atmosphere" in the Moon, it's just really thin.

And as such this happens:

...huh.
