I'm sorry but the whole whippit comment at the top puts too many mental images in my head....

I wanna see someone at party run out of the cartridges to pressurize the whip cream can thing and see someone come in with a 30BPS marker and churn the snot out of it by sticking the barrel in the tub and lettin it rip!!!! hehehehehehehee I know I know... easily amused.

12grams of co2 liquid will still be 12grams of gas once it is allowed to boil off....its only the state thats changing nothing else.

True, but misleading. Every marker regulates volumetric flow, not mass flow. A little liquid through the reg will cause a high shot because 1 gram of liquid can do a heck of a lot more than 1 gram of gas.

In my mind, i would have said: a mL of liquid can do a heck of a lot more than 1 mL of gas. If they have the same weight like you stated, they have the same amount of moles witch should give the same amount of pressure given the temperature doesn't change. Is my logic flawed somewhere? I agree that a liquid with the same amount of volume as a gas will produce more free energy because of the augmentation of entropy caused by changing states.

My initial post was just stating 1g of liquid co2 when turned into a gas is still 1 gram of gaseous co2. I missintrepreted your first post thejere. I was thinking that you were just talking about co2. But you were trying to compare liquid co2 to plain old compressed air?
But since you used g's for the air it screwed my thinking all up.


michbich I think thejere is trying to say the liquid co2 keeps a constant gas pressure of around 800psi until there is no liquid left. If liquid sneeks past a reg(below 800psi) the lower pressure will allow more to boil off until it reaches 800psi or no liquid is left. I think he/she just mixed up mass and volume at the end of his/her last post since at the begining it seems that he/she was going to use volumes, but then used g's


IDK about volumetric flow or mass flow....Im just assumed a reg worked by balancing the force on 2 sides of a seal....a spring on one side and the regulated pressure on the other. As the pressure on the regulated side increases, the spring compresses, shutting off the flow to the regulated output. I suppose the flow could add an extra force onto the closing of the seal, but the reg is adjusted by spring tension, so really its negligable. The regs that we use dont regulate flows, just pressures(they do regulate flows in a sense, but are not adjustable in that way)

any way if its cold enough or the liquid is forced through the system faster than it can become a gas, the liquid would evaporte off on the regulated side. Causing the regulated pressure to increase past what it was supposed to.

blah blah blah....had more then deleted it, oh well other work to do.

glad I left Florida. You can walk into almost any general supply store in the NE and buy a box of 12 8 grams...

37.5 cents per 8 gram.

You can get a balloon inflater/charger for a few bucks more.

How the heck do bars in florida charge their whipped cream dispensers?

Back to paintball; you can make a nifty little booby trap with one of the chargers, liquid paint and a balloon. I made one back in the late 80s and we called it the 'James Bomb'...
