explosion yield calculations

  1. Keeweed

    Should the yield of simultaneous explosions (close to each other), scale to a character.

    So currently I know we don’t treat it this way despite calc members agreeing with a Rwby calc we should do it this way, so let’s make it an official rule / ruling. Should two explosives, preferably like next to each other, exploding simultaneous have their energy combined for the yield the...

    So, I noticed that in VSBW's Page on Explosion Speed Calculations, it mentions the Method cannot be used in Explosions that don't occur from actual explosives. "In order to use this method to determine a timeframe the explosion has to be caused by a explosive, in other words by a reactive...

    Consecutive Explosions

    How do we treat multiple small explosions as AP/Durability in terms of calcing them? Like Would say, 10 9-C explosions be just 9-C or 9-B/9-A? For exact figures, do we just add the Tons of TNT of each explosion together?

    Ground Explosion Order of Operations

    So, the formula for Ground Explosions is this- (with P being 1.37895 bars) R^3*((27136*P+8649)^(1/2)/13568-93/13568)^2 But does that mean the Top or Bottom equation?

    Explosion yield formula under different pressures?

    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.

    New Way to Calc Pillar Explosions (Brought to You By Dragon Maid)

    So over on Discord, DMUA talked of a way to calc pillar explosions that I have only ever seen used once before. That was in this Dragon Maid calc. At the time, this method for the Dragon Maid calc was dismissed, seemingly for the reason of "this isn't how we calc explosions." But, again...
