Yeah condensation is expected -- decompression results in cooling, compressor results in heating. It's the whole refridgeration loop used in HVAC but applied to air guns. Filling a vessel causes a temperature rise, decompressing a vessel results in temperature reduction. Shooting 300 rounds...

That sounds perfectly reasonable and sane to me especially if you already have it. The only report of corrosion I am aware of is a Benjamin hand pump that had a rusted up internal cylinder? Regarding condensation during cold weather, I was thinking, Charles law and Boyles law, wouldn't the...

A gas will expand to occupy the volume of the containing vessel. An increase in pressure is an increase in contained mass or an increase in temperature. Unless the pressure vessel is a vacuum a gas present occupies volume, and mass, at a given pressure, at a given temperature. Charles and...

This doesn't make much sense to me. Sounds like you are assuming the water is in vapor form and will escape or change its form if the tank is opened. Ridiculous - drain the air, open the tank and dry it out. Also - 15 mL = 15cc = 15 cm^3

Nothing incorrect in what you stated. However in the HV AC system vast majority of the cooling effect is from the heat of vaporization changing the refrigerant from a liquid form to a vapor form.

I believe that it is confusion about this process that has led to the misconception by people who should know better, that heat build up in hand-pumps hand compressors, magically make water that wouldn't otherwise occur in a cold machine.😉

1) You use diameter of port rather than area because you're not calculating the force being applied over the ports area, thats not how this calculation works, its approximating the max flow for your bore. So if you're ported to 75% of your bores diameter, you're essentially making 75% of your...

@qball You were the one making thought experiments in the beginning, some basic physics calling you out is not theoretical or a thought experiment. I quote you: "Think about it, first reg has the same passage size as second and second one is restricted. If the first one isn’t restricted and...

LOL :) "You" (Non-targeted, I am quoting you and I mean no offense, I am expressing general feeling on this forum in the last 3-4 months) all are pushing Alkin like Amway. Don't get me wrong, I realize time is money, money is time, and all things mechnical break. Instead we get a whole lot of...

That same scuba store I was going to go to does hydro inspections, maybe I should do that. It was done in 2016, but I guess who knows what went on during those 4 years. They fill it up with water and dry it out right? I'm guessing maybe that's a good idea. Last hydro was 2016 Yeah there is...

PCP does not radically increase the temperature in the gun. Heat is created when the air is compressed (boyles law) and the compression is done when the bottle is loaded from the pump or the tank. The temperature will DROP as the pressure is released. 3000 psi in the gun, the valve opens and...

Gas pressure is a product of temperature and is explained by Boyle's law and Charles' law: https://en.wikipedia.org/wiki/Boyle%27s_law https://en.wikipedia.org/wiki/Charles%27s_law https://www.grc.nasa.gov/www/k-12/airplane/boyle.html https://www.grc.nasa.gov/www/k-12/airplane/glussac.html...

...to the valve perhaps thermally accelerated? MTBF seems to be accelerated at increased pressure at increased runtime. Charles law and Boyle's law and all that stuff. From time to time it feels like we're engaging in a Scientific Cargo Cult in the Compressors sub-forum and we're loosely...

Yes, and it’s proven via Boyle’s law; the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. The long/short is if you increase pressure, volume is reduced, and if you increase volume pressure is reduced, so 80 cf at 3,000 != to 80 cf at...

...your full 36 fpe. Time to stick a really heavy pellet on there and voila 38 fpe? WTF why? Barrel time. Pressure has more time to obey Boyle's Law with a heavier pellet. Turbulance in the valve and transfer port were eating up your additional power. Well, that would be my guess. To be...

...less (by several orders of magnitude) than compressor failure for the reasons of thermal failure as a result of Charles law and Boyle's law. I believe anything that obstructs compressed air output increases the work load on a compressor. I believe that moisture filters after the LC-110 are...

You are correct and I agree with you in principle and Boyle’s law is a fact. Many people that want to get in to PCP airguns scrimp and save to have enough cash to buy that dream rifle and they don’t have the $2500 left to buy a cheap decent starter compressor and a tank to store and transport...

This thread has gotten a little off track. Back to your original enquiry. You have misunderstood the point that I was trying to make. The input air for your shoebox is going to be supplied from a doner scuba bottle and nothing else, right?. If that's the case, the same amount of air is going to...

OK, time for some high-school physics ...... Boyle's Law says that pressure (P) x volume (V) = constant at a fixed temperature If you mix two volume of gas, one at P1, V1 and the other at P2, V2 and put it into a container of volume V3 and get a pressure of P3, then P1 x V1 + P2 x V2 = P3 x...

Thanks to the members of the forum who have, in a round about way, reminded me that when I’m diving I don’t have a cylinder with 80cf of volume (at ambient pressure of course) strapped to my back, therefore Boyle’s Law will not grant me the mythical amount of air required to run the Shoebox for...
