Discussion Overview

The discussion revolves around the effects of a grenade explosion in a vacuum, specifically comparing the damage and noise produced in a room without air versus a room with a normal atmosphere. Participants explore various aspects of the explosion's impact, including types of grenades and the nature of damage caused.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Some participants suggest that there will be less noise for neighbors in a vacuum compared to a normal atmosphere.
  • There is a question regarding whether the damage caused by the grenade will be the same in a vacuum as in a regular room.
  • One participant proposes that fragmentation holes in the walls may be deeper in a vacuum.
  • Another participant notes that the type of grenade (Fragmentation or Concussion) could influence the outcome.
  • It is mentioned that the type of damage considered is crucial; in a sufficiently large room, the absence of a pressure wave means that energy may be directed more towards shrapnel speed rather than structural damage.
  • Concerns are raised about the practical application of detonating a grenade in a vacuum, including the challenges of removing air quickly.

Areas of Agreement / Disagreement

Participants express differing views on the nature of damage and the implications of the explosion in a vacuum, indicating that multiple competing perspectives remain without a clear consensus.

Contextual Notes

The discussion does not resolve the assumptions regarding the size of the room or the specific conditions under which the grenade is detonated, leaving several factors open to interpretation.

what will happen when a grenade blow up in a room without air in it?

will it make the same damage as it would in a regular room?
like what will be the damage in a vacuum chamber and will there be a big difference if in a room with normal atmosphere

The fragmentation holes in the walls will be a bit deeper.

Hey, you have sinister plans with this, or what ?
Any practical application ? Will be hard to pull the pin and get out and then suck out all the air in a few seconds ...
Explosive doesn't need atmosphere; damage will be about the same.
 
The type of grenade (Fragmentation or Concussion) might make a difference.
 
Also heavily depends on the type of damage you consider. Assuming the room is large enough there won't be a pressure wave to consider, meaning that energy rather goes into shrapnel speed. So, you might perforate the well extremely well, but the structure might remain standing.
