Method 3.3L whipped cream charger, regulator, and oven bag.

[timechained]

A peaceful death...??

I am desperate to leave this world.

My plan is similar to the exit bag. I am going to:

- sit against the corner of my wall so I don't fall over
- attach the pressure regulator to the 3.3L tank (2050 nitrous gas, largest size available).
- place the oven bag (35×48) over my head, place a rubber band at the base.
- insert the hose under the rubber band to flush out CO2
- set the flow rate to 12-15
- try to go to sleep and hopefully don't wake up.

Please let me know your critiques or thoughts.

Those are my thoughts regarding this idea:

Exit Bag and Inert Gas Basics —A very, very long post, I know, but I feel like I've fielded a lot of questions about this, so I figured I'd spell out everything I know. Others on the forum should please add to this thread whatever reliable technical information they feel is appropriate for...

Thanks. I'll read it again.

- attach the pressure regulator to the 3.3L tank (2050 nitrous gas, largest size available).

2000 g of N2O is approximately 1000 liters at atmospheric pressure, this amount should suffice for an open system. A CO2 regulator would probably be the best option in this case, since N2O and CO2 have nearly the same molecular mass and density of the gas form. I guess, the operating range should include 20 - 60 bars, since the initial pressure would likely be somewhere near to 50 - 60 bars and then the pressure of vapours may drop down to 20 - 30 bars as nitrous oxide becomes cold due to evaporation of liquid N2O.

- set the flow rate to 12-15

I guess, 15 - 20 or even 20 - 25 lpm would be a safer range, since a significant drop in the input pressure would likely occur within a few minutes, and who knows how well the regulator would be able to maintain the output flow rate at nearly the same level then...

You could also consider closed systems (working without maintaining constant gas flow) for CTB with N2O

It seems, there are special regulators for such N2O canisters.



The problem with the presented model is that it doesn't measure the output flow rate, so you'd have to assess it using some external tool or setup.

Yea the outflow speed is one of my concerns because it's a single use pressurised canister but will see how it goes.

I've decided to cut a whole in the top corner and then duct tape the the tip of the pressure hose so that the gas flows downward.

I am going to use a necktie around the base of the bag (easier to adjust) since I can't use a rubber band now.

I decided to make the proper exit bag instead and not cut a hole in the top of the bag.

15L/pm is a lot of pressure. If it wasn't for the elastic band the bag would have blown off my head. Lol

I now understand why they use 2m of plastic tubing. I am such an idiot for rushing things and doing it without it.

Nitrous makes you feel amazing though.
I felt so light, it was like gravity just vanished. Lol

Fuuuuuck, I hate that failed. Scuba mask it is...!!!
