How long would my tank run for

[Bengal]

We always talk about a 15-20 LPM flow rate but distributors don't seem to tell us how many liters of nitrogen are actually in the tank. Makes it hard for me to know how long a tank will run at a certain LPM before it's empty.

I already know I have enough but I'm just curious and we have some very knowledgeable people here.

I have a 304 cubic foot/2,640 PSI tank and wanted to know how long that would actually run for at 20 LPM.

(I do have a smaller tank too. I guess just in general I'd like to be able to figure out how many liters of nitrogen are in a tank if possible)

20 cu ft is 600 liters of Nitrogen gas, so you possess a huge tank--300 cu ft is 15 times! what you need, so multiply 15 times 600 liters, thats a whopping 9000 liters of Nitrogen gas!--So, 20 lpm into 9000 equals how many minutes the tank will last, that's 450 minutes! but only 30 minutes is needed--Feel free to ask this question on the Inert Gas Mega Thread

Ty. Still kind of a noob around here. Will do next time.

But that info does help me with my non ridiculously huge tank in case I end up having to use that. Much appreciated

I was thinking along these lines as well.

My original plan was just getting liquid nitrogen from a welding shop and just letting it degas in a confined space/tent. But would much rather die laughing, not trying LOL so leaning towards the nitrous oxide route but fuzzy on the mechanics of the thread adapters on those medium sized whipped cream or straight up NO2 tanks.

What kind of pressure regulator and thread adapters would be compatible with the smaller nitrous oxide tanks (like those medium size whipped cream nitrous oxide tanks) or medium sized N2 tanks are the standard ones that are universally compatible?

Any specifics on the thread adapter sizes and or recommendations on regulator valves to port out into oxygen mask (or full-faced sealed respirator)?

Would it be a good idea to have a very long length gas line out coiled up and covered up with a heating mat since the gas would be coming out super cold and ideally warmed up via the long coil up set up or wouldn't be an issue?

Thanks
