Default At what PSI does a plastic soda bottle explode? (home CO2 carbonation)

This tire volume calculator works better:

My P225/55R16 Traction=A, Temperature=A, Treadwear=480 car tires calculate
to 14.76 liters each (60 liters for four tires).

So a four-foot manifold with eight 2L Coke bottles hanging down would
completely fill one tire.

From: Coca-Cola Support

Thank you for contacting The Coca-Cola Company. We appreciate your interest
in our Company and our brands.

As you know, the amount of PSIs (pounds of pressure per square inch) that a
package is able to withstand depends on the volume of carbonation and is
based on the product as much as the package. At lower temperatures, the
pressure is lower, and at higher temperatures, the pressure is higher.

Carbonation is measured in "volumes." One volume of CO2 is equal to one
liter of carbon dioxide dissolved in one liter of liquid at standard
temperature and pressure. Two volumes are equal to two liters of gas in
one liter of liquid, etc. The amount of CO2 absorbed by the liquid is a
function of temperature and pressure. The colder the liquid and the higher
the pressure, the more CO2 it absorbs. One volume is equal to 14.7 lbs.
per square inch (psi) pressure at sea level and at 60º F.

All PET packages can withstand 150 PSIs - the industry standard. However,
some of our PET packaging can withstand 250 PSIs. Unfortunately, we will
not be able to provide a list of which ones can withstand 250 PSIs.

We certainly appreciate your interest in our production processes for our
brands. However, in order for us to remain competitive in our industry,
some information is considered proprietary, and we are unable to share it
with the public.

We hope this information is helpful. Please feel free to contact us again
should you have any other questions or comments.

Sincerely,

Johnetta

I've built a home carbonation system. The gauges say I've put in 150PSI of
C02 into the Trader Joe's (admittedly thick) carbonated water bottles.

Nothing happened (with respect to explosions).

Yet, as I dig on the web, I find that plastic soda bottles are supposed to
explode at 120 to 150psi.
http://community.nbtsc.org/wiki/HomeMadeSoda

Obviously I need more data.

Do you have data points showing when soda bottles explode?

PS: If there's a soda or carbon dioxide related newsgroup for home
carbonation, please let me know.



Particularly on topic for me because I have an Air Horn on my bicycle:

http://www.amazon.com/Delta-Airzound.../dp/B000ACAMJC

It uses what appears to be a slightly thicker version of a soda
bottle. It is a very effective horn, in fact, a bit too loud.


RTFM - it has a volume control.


That's no volume control - it's an on/off switch. They can say
whatever they want but I own one. Any touch strong enough to release
the air causes enough noise to make someone jump.

There is a VOLUME CONTROL on the side. It is a little knob connected

It's one of the bright red or orange bits on the side. Just a little
lever attached to a cam that constricts the hose as you rotate it.



You are correct and you have made my life a little bit better. That
horn was really too loud and now I can attenuate it so the target
doesn't die of a heart attack. It gets so messy when that happens.

I have to attach it to my new bike. I don't bother using it during the
winter because there aren't that many joggers clogging the bike lanes.
Now they're out in full force.

I hydrostatically tested one at 150 psi (a cheap thin one) and it was
just fine. HTH :-)

What volume of gas is contained in an automotive ti
http://www.madsci.org/posts/archives...5256.Ch.r.html

Those guys came up with 10 liters at 30psi, given:
* Inside diameter of rubber tire 15" = ~40 cm = 4 dm
* Outside diameter of rubber tire 21" = ~50 cm = 5 dm
* Width of steel wheel 6" = ~15 cm = 1.5 dm
* Pressure inside the rubber tire 30 psi
* Temperature 25° C

The volume inside the tire is the volume difference between two cylinders,
one representing the entire wheel/tire assembly and the other representing
just the wheel.

The volume of a cylinder is V = p × diameter × height where diameter is
twice the radius.

Note: For your particular tire and wheel assembly, you can use the Tire
Diameter and Circumference Calculator at:
http://www.csgnetwork.com/tiresizescalc.html

They used the numbers below:

For just the steel wheel, the volume p × (4 dm ¸ 2)2 × 1.5 dm = 19 cubic
decimeters (i.e., 19 liters).

For just the rubber tire assembly, the total volume p × (5 dm ¸ 2)2 × 1.5
dm = 29 cubic decimeters (i.e., 29 liters).

The volume difference is just 10 liters (which means that the air in the
tire will mass about 26 grams).

Another volume calculation is he
http://www.irday.com/html/Automotive...0413/9827.html
Those guys came up with 30 liters for an average truck tire.

This volume calculation puts a car tire at 1 to 2 cubic feet of air:
http://mgaguru.com/mgtech/tools/ar104.htm

BTW, what happens to the mass if we use a different gas than air, like
carbon dioxide?


Many people are using nitrogen in their tires now and paying a premium for it. The benefits are not so from the physical qualities of the gas, but the fact that the gas contains absolutely no water. So the tire pressure changes less due to temperature changes.

Be careful you know they don't check them all, only a significantly large statistically relevant sample. A bad batch of plastic and not all the defectives may be removed be fore shipping.

Some of the benefits most certainly are from the physical properties
of the gas. Aside from the benefits due simply to lack of water
vapor, the hydrogen migrates less thru the tire structure and that
makes the tire pressure stay up longer then when you use plain old
air. In addition, the nitrogen does not oxidize the tire materials
the way the oxygen in plain old air does and that also is beneficial
to tire life. All that said, for most people the benefits of nitrogen
are relatively small and if you pay much for it you may not recover
that extra cost. For truckers the benefits are much
greater,particularly the benefits of the tire components not being
oxidized since they will retread a truck tire many times over it's
carcass life. And with nitrogen the carcass will last longer.

I've heard that you can use metal lamp connector rods that are threaded on both ends. Apparently someone did that with water bottle rockets. http://h2orocket.com/water-rockets/lamp-rod-rockets/

When I was stationed in California, back in the 80's, I used to belong to the
"Soda Butler" service. Monthly they'd bring a new CO2 cylinder, the soda
syrups of your desire, and new 2 liter bottles, if need be. The regulator was
set to 5psi. You'd add syrup to a line, fill with filtered water, unless you
liked chlorine tainted soda, place the special cap on the bottle, (which had a
heavy duty schrader valve) connect the hose to the bottle cap valve, and
shake, shake, shake. I found that the longer you shaked the more CO2 would
"scrub" into the liquid, so I could control the amount of fizz. It was a great
system as I never had any flat soda, no matter how long it was left in the
fridge, just scrub (shake) more CO2 into the liquid and like magic, fresh
fizzy soda. Shaking was mandatory to scrub CO2 into the liquid at 5 psi! Hope
this helps!

At 150 PSI, they would be useful as expansion tanks for air compressors. Now, someone to make a manifold so we can string together a bunch of two or three liter bottles. Watch. Harbor Freight will have them next week.
==============================
Careful!
If the plastic bottles are right off the compressor the air will be hot and that's a game changer for the plastic bottle specifications. It may work if the bottle storage was well down stream, and away from the heated air, maybe at the point of use. While It may be tempting
to reuse bottle caps for a DIY manifold, I wonder if the cap 'seals' are for tamper proofing or do they aid in securing the cap with higher pressures? I don't know but it could be exciting to find out! I think metal, or solid plastic caps are available online that would be more suitable. I use 2L bottles, pressurized to about 50 PSI to dispense lubricant to a CNC router cutter when machining aluminum. So far there's been no problem at that pressure and I reused a cap. The lube is water based and there's been no plastic reactions either.
Might be a worthwhile idea idea to put the 'air bottle' in a PVC tube just in case there is a problem. I have my 'dispenser' bottle in a PVC pipe with a glued bottom cap and a slip fit top cap to allow pressure release and changing, yet still provide fluid containment which should help any embarrassing Uh Oh's ! Good luck, and post your success. Remember that there are 'no failures'. They are just a long list of things that don't work!

At a MS science competition last year involving launching plastic

was decided on IDK.

That looked like a lousy bottle, and the bottle never broke. It was the
cap that did, every time. Drilling holes in the cap does not help it's
strength.

I've had bottles of cider that naturally fermented that were rock hard.
It took me days of frequent slow bleeding by loosening the cap a tiny
bit to get them down to where I could open them to drink. I have never
had one break. 2L bottles.
