Ooooh, there we go! Cold, hard facts! Thank you! I haven't had enough coffee yet to fully comprehend those equations (and math actually gives me a rash), but once I DO have an equation, I can work it out. So that will help me greatly! :)

Enjoy your donuts! :D

Don't try to wrap your head around it quite yet. I left out one rather important variable. I'll fix it in a few minutes

Oh, CRAP, this is physics? I don't do physics! Oh, wait, yes I do. When I trip on a frozen cow plop, I fall down, go boom. ;)

OK, I'm going for more coffee now... :lol:
Well technically this is thermodynamics and hydrodynamics but then again so is iboiling a pot of water so not really a big deal. :D

As a general rule of thumb I try and keep my heat flux reading near 200.

For 28g wire I never build lower than 1 ohm, usually around 1.2 - 1.5 ohms, at 15W it provides a nice vape.

For 26g wire I usually build in the 0.8 ohm range and at 20 to 25W it provides a nice vape.

For 24g wire I usually build dual coils in the 0.3 ohm range and at 65W, the vape is warm and quite cloudy in a dripper.

These are just what I do, I don't like fine gauge wire, I like to be able to yank the Rayon through a coil with the Leatherman... :lol:

I have a 24g single coil in my Aqua II at the moment 20W @ 0.6 ohms, the vape is a little on the cool side but more flavorful with the juice I am using than running it at 25W.

It is something you are going to have to play with to find your sweet spot, 95% of my RTAs are run less than 30W and the drippers with MaxVG I usually run at 65W.

Thanks, I'm starting to see the light. ;) I totally get the different flavor thing. With the exact same tanks and coils, I have one dragonfruit/menthol juice that I keep at 20W because it tastes best there. Then I have a strawberry cupcake juice I made that tastes bland at 20, good at 25, but BEST at 30W. If I go up to 35W, though, it starts being too "hot" for me, so I don't usually go over 30 now. But if a different coil made something taste better at 40, I'm not afraid to experiment. I live to experiment! LOL! That's the best way for me to learn new things. By making mistakes, and having successes. :D

This is a good example of when Steam Engine does sort of work. If you stay within four to six gauge numbers of each other (which most do) the error isnt too obvious, but if you were to go between say 22 gauge and 32 gauge you would observe that the heat flux number is way off.

Steam Engine does everything else pretty well.

I made some strawberry cheesecake flavor 13 days ago, ran it through 35 cycles (ours does 8-minute cycles only) over a period of two days, and I still couldn't smell any hint of cheesecake. The recipe said it needed to sit for 3 or 4 weeks, and after all that shaking and vibrating, two weeks later, I'm starting to smell *something* good. I had a tank of it a few days ago, and it tastes really good, but I still don't get cheesecake flavor. I used Capella's NY cheesecake, which from everything I've read about cheesecake flavors, is one of, if not THE, best one there is. So what am I missing with the ultrasonic cleaner? I used hot tap water and refreshed it when it got tepid. (Our "hot" is only 115F right out of the tap, by the time it gets poured into the US cleaner, it's prolly 108F to 110F.) I don't think I "cooked" the flavor out of it. I'm doing my best to let the rest of the bottle sit for at least another week or two before trying it again.

Some things only time will help. I like to vape Latakia tobacco DIY juice. Doesnt matter how many hours I steep it in a UC, it always takes about three weeks for the essence of smoke to become part of the vape flavor. Probably what your experiencing with your cheesecake. With all the hours the custard of mine has steeped in the UC it is ready to vape now and will be good, but in a few weeks it will be a bit better.

It gives me crossed eyes and an anxiety attack -- I had to scroll real fast over his post so I didn't have the vapors. :D (the BAD kind!)

This is why I shouldn't try to write physics equations on 4 hours of sleep and 20 hours of work.

I forgot to add one diameter of the wire to the ID when calculating the cylinder lateral surface area.

I'll write up a corrected formula once I've had breakfast.

At least you gave a forewarning this time. :D

I think *physics* is fascinating... too bad it requires all that math to describe. :(

Well, at least my cheesecake juice doesn't taste like soap. I bought some strawberry cheesecake juice when I first started vaping, and it was AWFUL. Strawberry by itself was wonderful, so I figured it was the cheesecake that tasted like soap. So I was always afraid to order any more, but when I started DIYing and reading reviews on flavors, the NY cheesecake had like 5 stars and everyone was raving about it. Not one person said it tasted like soap. Just that it needed a long steep time to bring out the luscious cheesecakiness of it. So I jumped. :)

Oh, NO! Not the BAD kind! :lol: OMG, I'm dying here!

Ok back to typing on a phone...

D = diameter
r = radius
h = height (or width)
W = watts

coil inside D + 1 wire D = cylinder D

1/2 cylinder D = r

wire D • number of wraps = cylinder h

Surface area formula (Area
= 2πrh)

W/Area = heat flux in watt per area.

OK, Mr. Boden sir, is this the missing piece? The part in italics? Or is that yet to come? The rest of it looks like definitions, which I had figured out already. I don't think more coffee helped me. I think I have the vapors! (Take THAT, mathematics! ROFL!) I want to think of "height" as "length." I guess it's because my coils are horizontal. ;)

There is a Squape Rs and Snapdragon waiting in my P.O. Box when I get home. I'll have a Rayon build in the SQRs after it's cleaned of machine oil. Also I should stop by the local B&M to get the resident coil master to spin me up a Clapton for the Snapdragon.

Only 9 days via ePacket from 3F to my P.O. Box is not a shabby delivery time. :thumbs:
