She’s shown the building and operation of her ventilation system. It’s not great.

But she said right in the video how it's so good it captures all but the finest particles! /s For serious though, I would assume that fine airborne particles would be the easiest to move? But I dunno anything about ventilation.

Extremely fine particles are easily removed with electrostatic filtering and larger particles are easily removed with physical filtering. There's a little gap at about 0.3 µm where particles are too large for electrostatic systems to easily draw them onto collection plates but small enough to flow around the fiber of a physical filter. That's why protective equipment like N95 respirators are rated at 0.3 µm. The effectiveness numbers are all "worst case". Shifty Pony fucked around with this message at 13:28 on Dec 6, 2023 |

If it were actually a problem you'd be more worried about o2 and n2 separating out and your bunker spontaneously catching fire

ComradePyro posted:every time one of her videos gets posted all the armchair engineers prophesy doom. I have no idea if what she's doing is safe, but I'm willing to bet she has a better idea than I do. I think she's great two days. it took two days for this thread to turn back into the comments section of her tik toks. please at least be funny or interesting when you deliver your prophesy, nobody cares about screenshots of dust. she is literally wearing a respirator in the screenshot. that's better than a lot of professional operations. the tunnel is dumb in a cool way and we should all get over the dumb part so we can enjoy that it's also cool. rule of thumb: if she dies and your joke isn't funny anymore, it was never funny. for fucks sake ComradePyro fucked around with this message at 05:01 on Dec 7, 2023 |

There's a little gap at about 0.3 µm where particles are too large for electrostatic systems to easily draw them onto collection plates but small enough to flow around the fiber of a physical filter. So what do you use to get the particles below .3µm (and bigger than ?? µm where electrostatic is effective)?

babyeatingpsychopath posted:So what do you use to get the particles below .3µm (and bigger than ?? µm where electrostatic is effective)? The particles collide with the filter media (commonly spunbond polypropylene) and become bound to them via van der Waals forces. How exactly they’re most likely to collide with the filter depends on their size. Small particles are jostled around like mad by collisions with gas molecules. They take such long random paths that they are sure to encounter a filter fiber somewhere along the way. This is capture via diffusion. Large particles go with the flow. They have enough mass and therefore inertia that individual gas molecules don’t greatly affect their course. This sets them up for inertial impaction. The air stream makes an abrupt turn around a fiber, and like a police cruiser chasing a motorbike, the particle crashes. Even when no sharp turns are involved, large particles my simply graze a fiber and stick to it. This is interception. The largest of all particles fall out of the air in fairly short order irrespective of anything else. This is settling.  Some diagrams show yet another mechanism, sieving, where a particle is just too big to fit through the gap between neighboring fibers. This is how the public thinks that all filters work. I’d describe this as a case of interception though.

I love the thought of someone being on the outside, holding the rope to pull her out in case of hypoxia and such. I don't think that's set up to happen as a safety precaution. But I like the idea. Here's hoping she thinks of this idea, too, soon.

I'm just imaging the safety line and her limbs catching up on all the scrap lumber, nests of extension cords, other rope, compressed air lines, and what not I've seen in her other vids, so the end result is the safety line pulling out a lady trapped in the midst of a mess that looks like it was drag netted from the bottom of an active marina.

Just have a winch set up to start running if you don't press a button every minute.
