What Is This Thing Called Knowledge Pritchard Pdf To Word' title='What Is This Thing Called Knowledge Pritchard Pdf To Word' />All that is required is to place CO2 carbon dioxide gas in agitated contact with chilled water for a few seconds. In this essay, Ill show you how it is done with easy to find parts and common PET polyethylene terephthalate, sometimes. PETE soda bottles. Ill also explain the kinetic chemistry of why it works so well. And in the second half of this essay, Ill explain how I progressed from this improvised apparatus to installing. The Gas Supply Tank and Regulator. The essential ingredient is a supply of CO2 under pressure. CO2 is sold commercially in steel tanks of various sizes. It is actually a very inexpensive material, considering the special handling it requires. In my area you can refill a 2. Larger tanks are even cheaper per pound. Many soft drink or beer distributors will swap your empty CO2 tank for a full tank at. CO2. for propulsion. You shouldnt have to invest more than 7. A 2. 0 pound tank is so called not because it weighs 2. CO2 in gas over liquid form aka. The empty steel tank and valve weight about. I prefer this size tank because it is the largest that is. Tanks smaller than the 2. CO2. On the other hand, the giant 5. The actual weight of my 2. Apparently the 2. I wasnt getting a complete fill from. The regulator adds about 3 lbs, if youre trying to weigh. Tanks also vary slightly in size and weight depending. The tank alone is not enough to supply the gas. One must attach a. Twenty pounds of CO2 carbonates a lot of water. We consume several. The. 2. 0 pounds of CO2 in my full tank yields over 1. Since my techniques. But the. process is so cheap that I havent bothered to precisely measure it CO2 expense is no more than a few cents per 2 or 3 liter bottle. Another source of gas is CO2 fire extinguishers, which are made typically from. On several occasions I have bought these extinguishers at. When empty, the gas dealer can then. Tanks should also be inspected internally and. Physical Properties of CO2 Relevant to Carbonation. Density. Gas. 0. 1. F, 1 atm 1. 9. 8 gramsliter  0. F, 1 atm 1. 8. 4 gramsliter Solid.

The slightest leak, especially ahead of the regulator where the high pressure exists. CO2 supply in a matter of days, or less. CO2 tanks and regulators use a unique flat nipple fitting CGA 3. NGO RH EXT, flat nipple. CGA 5. 80, 0. 9. 65 1. NGO RH INT, such as for argon, nitrogen, or helium. The flat nipple squeezes against the mating tank outlet, being compressed by a large captive nut, with. You must firmly attach the regulator nut with a new washer to assure a leak free fit. Each time the tank is filled, the supplier should give you a new washer for the regulator connection. I find it so difficult to find high pressure leaks that I have taken to disconnecting the low pressure. The ordinary soap bubble method works fine to find leaks on the low pressure side. I actually have two of these 2. This assures a continuous supply when one tank empties, I can have it. I use an adjustable regulator that I have set to deliver about 4. CO2 regulators are available for about 5. There are special regulators made just for CO2, and fixed pressure CO2 regulators, but. CO2 fitting. I connect the CO2 gas delivered by the regulator to 14 inch ID flexible. Unbraided 14 inch vinyl tubing will burst at low pressures, especially if it. I learned this the hard way one day when I had the supply line. The. working pressure of the unbraided tubing was reduced by the heat to the point. After that experience I switched to braided. But I. still use unbraided tubing for the final section to the bottle, as shown in. The Shutoff and Gauge. The gas delivery tubing runs from a kitchen cabinet holding the tank and regulator to a wall mounted. While not strictly necessary, without a separate shutoff. The shutoff and gauge. The shutoff provides control over the carbonation process, while the gauge provides. The ball valve requires only a quick 14 turn of the handle for full on or off. The tee and gauge are optional, but help in monitoring the carbonation process and. The female quick connect allows easy selection of final hose and cap. All fittings are 14 inch brass NPT, except the ball valve which is 38 inch only because. I made this in the 1. Web to help locate such things. Teflon tape in the threads prevents leaks. Copper pipe straps across the ball valve shoulders hold the whole assembly firmly against the. The quick connects are common air fittings available in auto parts and hardware retailers. Install Activex Webrec Cab Control more. This part of the apparatus is all that is normally visible in the kitchen. I enjoy showing it off to guests, but in 2. I dont seem to have convinced. The gauge on the shutoff panel allows me to monitor the performance of the regulator and to have a rough idea of. CO2 saturation in the water. My latest CO2 regulator is actually made for MIG welding these are the least expensive. Ive found and has an orifice restricter to limit flow rates, which requires that I. The gauge is connected after the shutoff valve, so it measures the pressure in the bottle. The gauge is also not strictly necessary. I use a quick connect air fitting at the output of the shutoff. This allows me to attach various hoses and caps for different bottle sizes. It also allows me to rinse the open hoses if they get a bit of backflow from carbonating. The Bulkhead Cap. So far everything has been ordinary parts from a gas supplier and the hardware store. While Ive gone through several designs to get the 14 inch hose fitted to the plastic soda bottle cap. While you might expect to use the common threaded fittings for tubing available at the hardware store. The solution is to use a clamp in tire valve from the auto parts store. This provides a straight threaded, stainless steel fitting with the right dimensions. The parts in a clamp in tire valve kit. This is a Camel brand part number 3. Pep Boys Auto Tire for a few dollars. Camel makes at least one other size, and other manufacturers make similar items, such as the. This is the only common source for a bulkhead fitting Ive ever discovered otherwise you have to look. Ive removed the valve stem the item in the middle with the red band using the stem tool on the right. Only the valve body, nut, and washer are needed the screw cap, stem, and rubber washers are discarded. You might wonder whether you cant just leave the valve stem in place in the valve, and. CO2. This does not work because the process requires. CO2 into the bottle via an open connection. Carbonating a 2 liter bottle requires flowing in about 8 liters of CO2. Puffing up the bottle from a tire chuck through a stem valve provides only an intermittent.
