    Illegal bottle!?!

    I believe the Yong Heng is compressing a non-ideal gas and this is causing my lawful non-compliance with Boyles and Charles law.

    5000psi (350bar) Air Tanks and Air Bottles – Do they EXIST??

    Only a matter of time before they use PCPs in the military…

    First off, to all who've mentioned serving our country, thank you! 🇺🇸 The physics in this case(Boyle's law) won't change. And if it does then there are aliens here...extraterrestrial, not illegal aliens, although the law would make ET's illegals too. :unsure: But seriously, airguns just can't...

    Illegal bottle!?!

    I am worried in the condition outlined that it would violate both Charles and Boyle's law, thus being illegal, but currently unknown if unlawful.

    300 bar only for 2 regulator guns?

    The gains in ACTUAL air one can use IS NOT PROPORTIONAL to the increase in pressure 250 to 300 bar as is gained 200 to 250 bar. Wear and tear on seals containing 300 bar is also far greater than at 250 bar. Going to 300 bar for gun filling in lieu of stopping at 250 bar is simply not worth it...

    BRK Ghost Review

    Yeah, I knew it was far from an apples to apples comparison..... Boyle's gas law. Aside from barrel accuracy, I've been wondering too if the balance valve is more efficient than a standard reg, valve and hammer spring setup like most other guns have. After all, FX tossed a valve stop in the...

    How do I calculate how much air is in a plenum?

    I'm trying to figure out who to use the tool, you need to fill in 3 values to get the 4th one. Initial pressure at 1 bar for base atmosphere. Final pressure for pressure inside the plenum and final volume for size of the plenum. This will then change Initial volume to show have much volume at...

    Notos losing some psi between shoot sessions

    With respect to my comments relating to pressure and volume, in case it helps, https://chem.libretexts.org/Bookshelves/General_Chemistry/Map:_A_Molecular_Approach_(Tro)/05:_Gases/5.03:_The_Simple_Gas_Laws-_Boyles_Law_Charless_Law_and_Avogadros_Law Pressure loss is excerabated when the volume is...

    Dual Regulators a fad or here to stay?

    Somethings many just never think about or realize ... Pressure at and above 250bar is not that much more air ( Boyles law ) Pressures as we go higher & higher extrude 0-rings and reduce there service life exponentially Friction of an o-ring Increases with pressure due to extrusion which is...

    Compressor Storage Location

    ...vapor. The colder the air, the drier it is. However, watch the oil viscosity index. Too cold may make the lube oil too viscous. Remember Boyle's law. If you charge a bottle to max pressure and then the temp rises, the bottle will become over pressurized and could possibly blow out the safety...

    Do time-wasting post titles aggravate hell out of anyone else?

    “Best compressor” ”Help me decide” ”What is this best airgun to use” ”Will this work?” ”Has anyone seen this compressor before?” “Physicists Hate Him For This One Simple Reason — Defeat Boyles and Charles’ law with this one simple trick!” ”Is this too expensive?” ”Why do you …”

    Illegal bottle!?!

    WHEN YOU COMPRESS AIR THE AIR GETS HOT. THE HEAT CAN BE REMOVED BEFORE IT ENTERS THE BOTTLE BY COOLING THE "TRANSPORTATION PIPING: FROM THE COMPRESSOR CYLINDER TO THE BOTTLE, IF ENOUGH HEAT IS REMOVED FROM THE COMPRESSED AIR DURING IT'S TRIP FROM THE COMPRESSOR TO THE BOTTLE THEN IT MIGHT BE...

    Notos losing some psi between shoot sessions

    I may be wrong entirely …. I want to be. Perhaps I should “ cool my jets “. Thank you for the explanation. That’s exactly what I was looking for and this makes sense. Love my Notos. It went right to the front of the pack of my carbines. I use to work in service at a local...

    Conduction heating of compressed air.

    ...in the plenum without slowing or interfering with the laminar flow of the air in the plenum. Add to that the cooling that occurs due to Boyle's law (reduced pressure cools the gas as it leaves the PCP storage)... There are a few issues that beg resolution. Just how many watts or joules of...

    New 300 bar air tank questions 🤔

    ...your gun's pressure and volume capacity, and at what pressure you choose to refill your gun? I worked that out once. You can use Boyle's law to get an idea for how many full-pressure fills you'll get out of a tank. https://en.wikipedia.org/wiki/Boyle%27s_law It states that in a...

    Compressor moisture example

    Eaglebeak it sounds like you're describing Charles' Law, Boyles Law, and the Law of Conservation of Energy as it relates to Entropy Exchange. None of this will summon the legendary moisture boogeyman though. :( Filters must be sold and emotions must be pacified. We should be fearful of...

    Backwards math to optimize energy output

    Ok, I grok Boyles Law. So you are suggesting that a set point of 2000 psi with a plenum of 30cc will have one pressure and the same set point will have a different pressure in a larger plenum? Right. Also trying to understand how the volume of air used per shot makes it's way into Boyles Law...

    M3 Delete the Reg!

    @qball It's not as simple as that. Your "think about it" that if the 2 regs have the same "passage size" they will fill at the same rate doesn't work. To get a bigger picture dive into the conservation of mass in an open system, ideal gas flow and a combination of Boyle's, Charles and...

    Hearing some water inside SCBA tank. Any issues?

    ...leave it alone. Once you open it up you can no longer observe it in the state it was, think Schrödinger's Law or like Charles' Law and Boyle's Law and stuff. If there is moisture in the tank, which is what it sounds like, then it's probably better to estimate the moisture amount using the...
