I need a favor from anyone who uses HPA or nitrogen tanks

How cold is the gas when it exits the tank? Specifically, I want to fill through a shrader valve with a chamber volume of 7 gallons.

It would be great if someone could measure the temp of the gas as it exits the fill adapter.

That entirely depends on tank volume, tank pressure (or upper and lower extremes at least), tank temperature, chamber volume and chamber pressure.

It's possible to calculate reasonably accurately the final chamber temperature with a little maths. However, obviously, not without knowing the numbers needed to do so.

EDIT: I should warn you, I'm going to bed now. If you really need me to do the maths, responses from me will not be prompt.

Hmm, combined gas law maybe? I'll see what I can figure out.
