does home depot fill Psintball CO2 tanks?

You could check at your local one, but I know mine doesn't.

Poppet valve would be your likely answer.\n\nCheck valve is also acceptable.

liquid propane and natural gas

I have seen them working. I believe they are the first refrigerators.  This one we had to turn down because the food was freezing in the main compartment. It seemed to work very well. The athletes bag that gets cold when you squeese it is also some ammonium salts dissolved in water.\nThe problem was I had an Uncle that passed out working on one because it uses Ammonia and water. If vented it can be poisonous.  I heard of a small box with a black panel on one side and the sun heat made the inside cool.\nThe heat turns Ammonium Hydroxide dissolved in the water into Ammonium gas and water. The mixture travels a little way outside and cools just a little. Inside the refrigerator, the tubing gets more constructed, the pressure goes up and the ammonia dissolves in the water. This is an endothermic reaction (takes heat from the environment) so it is cool. This travels more inside getting warmer and cooling the inside. Then it travels outside and into the flame again. I don't know how to engineer the amount and sizes of tubing. It does seem to work well. Perhaps for India a combination of solar and propane would work best. \nGood luck on your enterprise.

Yes it will rec0ck.  the only time it will not do that is when you are low on air or out of air.  when you are low in co2 it will sometimes sound like a machine gun going off.  just think of it this way, if you are using CO2, 20oz, by the 3rd hopper full you will need to fill your tank up.

PHYSICAL. Check out redunicorn's link.  I think it is physical as this site says.  The mentos are providing many sites for the CO2 bubbles to form.  Try pouring a pack of sugar into a soda and you'll see the bubbles come quickly to the top.  This is a less messy experiment that is the same.

The 5 gallon tank measures 0.6685 cubic feet.  The compression ration is 15 (150 psi / 10 psi) so the tank holds 15 times as much air supply as its volume, or 0.6685 x 15 = 10.03 cubic feet. So, at 8000 cfm, you run out in 10.03 CF/8000cfm = .00125 minutes or 0.0752 seconds.

nope.  no tanks from gaf, or at least none that i could find.  try the cesco ones, they're light and sturdy.\n\nhttp://www.calumetphoto.com/item/CS7310.html

I'm only 12 and I'm surprised that no one has answered this yet. First, what hapened is that something happened inside the factory...that information has not been released to the public yet. This caused there to be something happening to the CO2 which made it bad, so it was not safe to work with. So now they have to ration it until they get it all worked out. Does this help you any?

It depends on the pressure and temperature. 50 lbs. of O2 represent a fixed number of moles of CO2. From the ideal gas law PV=nRT. Cannot solve for volume V without knowing P and T.

You would need a tank about the size of a house (55ft cube) unless you compress the air then it would be much smaller.

Try KBR a Halliburton company.

most all paintball markers can run on either co2 or compressed air.  no conversion is required. unless your paintball marker does not have asa connection (screw in for bottles).  then a paintball professional is required

Helium, CO2, Hydrogen and various others.

Don't listen to the above post. CO2 is not flammable, and you are not necessarily asking for it to be pressurized. The cheapest way to get bottled CO2 is to catch the products of a combustion. I would try to suck the smoke of burning coal into a bottle. Another way is to make your own carbonic acid by blowing air from your lungs into watter. Of course using these cheap methods you'll never get a good sample (eg, humans breathe out about 20% CO2). Perhaps there is a way to get rid of all the gasses?\n\nActually, there are "air sponges" that absorb certain gasses. If you could pump air though enough of these filters to take out all the gasses you don't want, you could be left with pure CO2.

First, is the tank a coded vessel? If it is, you will have to follow the code's procedure. If it is not, will failure result in any catastrophic damage? If not, you can fill the tank and see if it leaks. Outside that, you'd have to see the particular installation and determine a safe test method.
