You need to figure in "Boyles law" also. John

First time I hear of it. Looked up what it is: https://en.wikipedia.org/wiki/Boyle%27s_law

Just for fun I just put it in the search here and : https://www.airgunnation.com/search/982351/?q=Boyle%27s+law&o=relevance John

Not sure about “maxed out by Bernoulli’s Law”, but we do work under Boyle’s Law which is still just an approximation at the relatively low pressures that airguns use, where air behaves much like an ideal gas. But once we get much above 3000psi, air becomes less “ideal”. So we are close to “maxed...

Mass flow limiting... Beyond my paygrade. Aside from bigger tank and longer barrel, if folks want "more" going up in caliber seems the next logical step, if keeping with hpa.

Charles and Boyles ideal gas law. Entropy exchange. https://chem.libretexts.org/Bookshelves/General_Chemistry/Map%3A_A_Molecular_Approach_(Tro)/05%3A_Gases/5.03%3A_The_Simple_Gas_Laws-_Boyles_Law_Charless_Law_and_Avogadros_Law

What is FPV? This is Boyles law "For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional" I mistook it for a derivative of Bernoulli's principle earlier, but its actually Boyles law. https://en.wikipedia.org/wiki/Boyle%27s_law

I had a Huben hand pump, it would do 5000 psi.

Physics 101 - Charles Law and Boyles Law. What you observe is normal so you can smile :) I have a very small tank I use and put it in the freezer before transfer filling from the larger donor tank.

There is also a Z factor in the equation to account for variation in temperature and pressure: https://en.m.wikipedia.org/wiki/Compressibility_factor Practically speaking, at the temperature we operate at, air is 3% less compressible at 200 bar, but that rises to 10% at 300 bar and 14% at...

Gotta love nerdy threads like this. According to Boyle's Law the equation to get the volume of air it seems to be linear based on pressure. Volume of free gas in a Storage Volume The amount of free gas at atmospheric pressure in a given volume - like a cylinder storage - can be calculated my...

Here’s a link. In the INITIAL VOLUMES and FINAL VOLUME boxes, touch the blue letters to find the description like cc’s psi etc. https://www.omnicalculator.com/physics/boyles-law

I think my Omega trail charger will do 4500, as I fill one of my guns to 4300 max.. but I'm not sure I'd want to try 5000 as it's close to the top end of the gauge.. it's been a great compressor for 8 years and unless I know for sure from someone else, I don't think I'd risk the compressor.. it...

I fill a small tank all the time from a SCBA tank. I am talking a tank so small it could be on a bottle gun. Put the small tank in the freezer first. Boyles and Charles law applies here. Same principle as filling 1# propane tanks from a 20# tank.

I have a 90cu-in Ninja tank and it can refill my Notos a ton of times from 4500 PSI. Anything above 90cu-in and you will be fine. I even have a tiny .5L (30.5 cu-in) pony bottle and get about 5 fills on my Notos. For the pony tanks leave then in a deep freezer to get a full 4500 PSI. Boyles...

Small air cylinder with temperature swings equals big pressure change. Larger cylinder with same temperature changes equals small pressure change. Boyles and Charles law — smaller cylinder means less volume. I own a Notos and the above math checks out :)

Yes... and when I got into work this morning (I thought about it all through shower and drive in) I searched some sources. I believe it is Boyle's law. The left side of the pic above is a smaller reservoir and as such will have higher pressure (closing the piston against the seal) than the...

Bingo. In the 150cc to 100cc differential question it certainly won’t be 50%. More like 25% if that.

I want to believe this. unless others confirm theirs are doing the same …. It doesn’t make sense. ( it’s a 15 degree flux ). Just like Boostcreep said … non of my other PCPs lose a drop it seems.

This is not quite true. You will get a higher shot count, but it will not be the same as the difference in the pressure available (150 compared to 100 Bar). I have long since forgotten the exact law involved (I think it’s Boyles Law) but the bottom line is that you lose a little efficiency going...
