I known that we use this calculator to find the yield in several feats that involve explosions; however, I noticed than that calculator use Airbust instead of Surface, airbust in a detonation in mid-air, but I used that calculator in explosions that happened at ground level, futhermore, I used surface explosion equation for this one when, in theory, I should have used the airbust one; I also recall some other calcs that do the same or similar.

So, should we use two calculators: one for airbust and one for surface, or still using the airbust one? If any, airbust is always lower than surface at the same radius.
 
Well, for the Asari one you shouldn't have used nuke calculator anyways. Just the KE of the ship right as it crashed. For the Big Bang I guess you could've used that but calc'ing it from the after effects would be better, and for the Jason one you could calc it based on the energy needed to heat up the air til it's white hot (temperature based on color is a thing but I'd need to find the values).

But, to answer your question, you should've used ground burst for all of these if you were going to quantify them like nukes.
 
I calculed the explosion in the Asari's one cuz finding the size of the ship and used timing from the video would result in strange results, if the ship has an official speed I could use that. In the second one, there's notable crater later, just the Tiwer destroyed since that Black Spot was nuked long time ago too, it was destroyed before the Big Bang. I could use fireball radius for the Jason's one, but need still need to known if use fireball radius for surface or airbust.
 
@Anton Ask Krukov what ship that is. There's probably a listed height somewhere, or at least a shot you could scale the height from. Nuke should be fine if there's nothing else to use for the Big Bang one. As for the Jason calc, I meant more scale the size of the explosion and then find out how much energy it would take to make all the air in that white hot (5000 K).

@Antvas For now I'd just say that instead of using the StarDestroyer Nuke Calculator we should use Nukemap since that has surface detonations as well as airbursts.
 
Oh right, I changed the Mass Effetc calc to airbust (low-end) until I can find the characteristic of the ship. I added to the Arclight's calc the surface result, and changed the Jason one to fireball radius (don't known how exactly works the method that you told me).
 
@Anton You should use groundburst for the Mass Effect one until you can find the ship. It didn't detonate mid-air, it collided against a shield. The Jason calc is a little like...

Say the fireball is 10 m^3 and the air was room temperature previously (297 K). Since making something so hot it glows white-yellow (What we see in the feat) requires 5000 K, find the energy needed to raise the temperature of 10 m^3 of air by 4703 K.
 
Changed the both calcs again, curious enought, both fireball radius and latent heat methods have similar results.
 
@LordXcano Should I temporarily unlock any pages for you, so you can adjust them accordingly?
 
@Ant I don't think that'll be necessary for now as I don't quite know the formula for groundburst explosions, just that that calculator can be used for them. I don't think it'd be a very good idea to pretty much delete the entire third step on the Explosion Yield Calculations page just to replace it with "use this calculator" until I get more info.

Although I suppose you could add "Be sure to use this calculator if the explosion is against a surface rather than in the air" as another sentence at the end of "Here is a sample calculator that you can use in order to find the yield of an explosion, provided that you have found the exact diameter of it." for now.
 
I think that it is best if you add the sentence, as I do not wish to screw anything up.
 
@Xcano, the surface equation can be found in my blog here, from that I had the chance to determinate bothe equations for 5 and 20 psi, is the same method that use the Nukemap, I checked several time and results are pretty similar.

I wouldn't like to make any major change with only two memebers, more input from the staff would be necessary.
