Wow, you never know where a thread may go but what a good education all this discussion has been. So learning that I paid for more N2O than I got if the guy said he got 11 lbs in my 10 lbs bottle? I'm going to use these threads to explain why they owe me money. BTW - I've had an A/F guage long before I got N2O. Innovate LM-1.
No Im saying Liquid turns into gas and then pressure goes up. So if you have more liquid as it heats up and turns to gas the pressure will go up. The size of the bottle is what determines how much N20 can go in, if it was only based on temp, then we could fill the bottle all the way to the neck. The volume of space and temp are what determines how much you can fit,(expansion rate) not just the temp. BTW-JMATT, you can see the frost line rise as I fill the bottle up, the highest up the bottle Ive seen it go is about 3/4 full.
Maybe not. Depends on how they label bottles. What size is a 10 lb bottle? I was thinking a "10 lb bottle" would be full with 10 lbs of liquid, but it seems that's wrong. Looks like they use some fixed temperature. At that temperature a "10 lb bottle" will hold 10 lbs of liquid nitrous. If the fill tank was at the fixed temp and the bottle was cooler it would hold more than 10 lbs.
Hmm, not sure what you're saying. Can you re-phrase that? You COULD fill a bottle all the way to the neck. The bottle would have to be VERY, VERY cold.
No. Still absolutel not true. The outside of your bottle may still feel like it's 60 degrees, but that's just because the heat from inside the bottle hasn't reached all the way through the aluminum to the outisde. Wait 10-20 minutes. If your bottle is 92 degrees, your pressure is 950. If you have a different reading, you have a bad gauge. It is physically impossible for N2O to have 1050 PSI at 60 degrees. Never happened in the history of the universe. How many pounds was that fill? I can probably believe the bottle got 3/4 full physically. And after talking with nitroussupply (see below) that seems to coincide with the "70%" number for a full bottle. I'm guessiong you full bottle weighed the 23 pounds, or whatever you said. And that was a 13 pound empty bottle with 10 pounds of N2O in it. Well - I know you can physically fit 11 pounds, or maybe even 12 pounds in a "10 pound" bottle. There's warnings on every bottle not to overfill. Personally, I don't want the vendor overfilling my bottles by more than about 1 pound. EDIT: I went ahead and called Nitroussupply, which is the company owned and operated by NOS founder Mike Thermos. They said a "10 pound" bottle is physically about 70% full at 10 pounds. So even if you could fill the bottle all the way to the top with N2O, it would only hold about 14 pounds. OF course he gave me the standard warnings about over filling a bottle. But I'm going to believe his authority, and suggest that 10 pounds is good, 11 or even 12 pounds is possible, 13 pounds is a bad idea, and 14 pounds or more is physically impossible.
Boy you guys are really starting to back up now, 1st it wasnt possible to fit more than 10lbs. Now 10lbs is 70%, once again the therories are flying out the window. Im telling you and next time I fill my bottle will take a picture, I easily and safely fill my bottle to 17#s. As far as dangers, yeah you pop a 20 cent tin cap in the pressure releif. JMatt Im not going to state as fact that my bottle was 60 degrees, I just know that with frost line up bottle 75%, I had a pressure of 1100 PSI and my bottle was 23#s heavier than empty. Its funny how you guys show all sorts of formulas and state laws of physics but then make a call and are told well you can get 14 #s. I know you cant take everything you read on the internet as being true but Im doing what you say cant be done, you guys are the ones calling nitrous companies:erm: I guess all that extra money I spent on that Whirlpool refrigerator was worth the money. O' and my 10# bottle is special too :thongue2: BTW- Explain how a steam engine produces more power(pressure) when you add water and more heat :welcome: This topic is dead :domotwak: , 12SecUV, sorry for taking the thread off topic.

My fault. I didn't know how bottles were labeled. As above, that was all my fault for a mistaken assumption on how nitrous bottles are labeled. It appears that the convention is when you call a bottle a "10 lb bottle" what that means is that it will hold 10 lbs of nitrous at sort of normal air temperature. It seems that a "10 lb bottle" has the volume to hold a little bit more than 14 lbs of liquid nitrous. In order to get 14 lbs of liquid nitrous in there you would have to cool the bottle to like -170 degrees. The important ingredient there is heat. You're just converting heat/energy into mechanical energy (expanding steam to push the piston) Well, maybe. But only because we've failed to explain it well enough.
You are completely missing the point. And you are still completely wrong. A 10 pound nitrous bottle is considered "full" when it has 10 pounds of nitrous in it. At that point, the bottle is 70% liquid and 30% gas. In theory, if you could fill it with 100% liquid, you could get 14 pounds in it, and the bottle would have to be -170 degrees. I will personally pay you $10,000 if you can post a video showing the weight of your empty 10 pound bottle, followed by you filling the bottle to the point that it weighs 23 pounds more than when empty. Oh - and while you're at it, take a video of putting 20 gallons of water in a 10 gallon fish aquarium. No one has backed up here at all. Your claims are simply wrong. Perhaps (probably) an innocent mistake, but you are putting completely wrong info out here that others will read someday. Rather thatn rely on myself, I personally called the number one nitrous expert on the planet. He confirmed my point, and debunked your claim. Sorry bro. No offense intended, but you are simply mistaken.
No offense taken, Hey your a lawyer right ? So is a post on a public forum a legal binding contract :baby: You know by the time I get back home, my donor bottle will be at 100 degrees and I might get 24#s in. Is that worth a even 15 Gs:king:
Hmmm, you never mentioned who makes your bottle... I'm getting a mental picture of a "Texas T 10lb Bottle" that's made from a 30 gallon drum.:grin:
If you in fact have a 10 pount bottle that you can get 24 pounds in, you get $15,000. But if you don't, I get $150. That's 100:1 odds in your favor. :whistle:
