When vaping I will often see bubbles coming up from the juice channel(s) Shouldn’t air come up thru the air holes anr equalize that pressure so that doesn’t happen? I ask because if I loosen the top of the tank, the bubbles happen more often. So is it better having a looser top or tighter top?
When liquid goes through to the coils, a vacuum is created in the tank, air is thereby pulled into the tank
So it goes thru the air holes into the chamber where the coil is then out thru the wicking material into the actual tank area… where I see it rising to the surface… interesting
I know ya just play a physicists on tv and all but… why would I get more air bubbles right when I loosen the top of the tank? I would think that would have equalized the pressure and wouldn’t have bubbles come up when I did it.
Yes! When you took a drag, you basically pulled juice into the chamber, leaving a vacuum in the tank. You vaporized the juice, so that means mostly air returns to the tank. A little bit of wicked juice does make it back into the tank, which is why you sometimes see a difference in color, when you’ve almost drained a tank and fill it - the liquid left in the tank is sometimes slightly darker (especially if the coil is not new)…
