Ok, but I was squonking it drowning. As in top off, squeeze until juice was almost running out the ariflow holes, AFTER the rest was pulled back into the bottle (Desire Cut) and it was burning a few seconds in above 65 watts. Every fathomable tip and trick is on the previous pages of this thread.
I knew I liked you when you first showed up here.
That IS EXACTLY what I was thinking about last night. For lack of a better way of putting it, maybe with those massive wicks, different areas of the cotton (or whatever material) are competing with each other over which gets the juice first. Then I thought, but there's really only one area going dry, that being the uppermost part that contacts the mesh. However, once that area is dry, it has to get more juice, which isn't coming directly from the well of course, but through the rest of the cotton first.
That is the key question. Does the dry part of the cotton, get more juice from the immediately adjacent cotton, and THEN the well sends more through the rest of the wick? OR does the well have to send more juice BEFORE the dry part gets what it needs? I'm theorizing that it's a range of both and that it depends on a few factors, not least of which is the volume of cotton. (The immediately preceding applies to any atomizer)
It seems counter intuitive on one level, but maybe with less cotton to compete with, it would get to the surface of the mesh faster. Not only that, but it weighs less and also isn't fighting gravity as hard.
With the Unity, there is an extra, low volume upper region of cotton that draws from the holes in the chamber, which are not below, but level with the surface of the mesh. No fight with gravity. The fact that it's a tank, as has already been addressed, of course means that back pressure is gently pumping liquid, both through the holes and the ports, which being lower get more pressure. Which is good because they need more pressure than the holes because they're lower.
Why do I not get dry hits at high wattage on the Drop for instance with it's 3 story high posts? On a series box and a .27 build. Because at some level the volume of cotton reaches a point of diminishing returns, where more actually wicks less efficiently for reasons that are somewhere in all this stuff I have presently been prattling on about. I think it's in there even if this isn't precisely right.
OR, I'm an over analytical blithering imbecile whom everyone one would do best to ignore.
