Twisted wire gauges.

[Rekon]

So I have twisted 2 26g wires together, that ended at the same ohm as 2 single wires.
Now the ramp up is doubled as of this, as of more mass more wire etc. So I would like to calculate a build to suite me more understanding this, to compare ramp up for future builds.

I've searched around trying to figure out how you can calculate what gauge 2 wires of 26 will become when you do this. Most sane thing I've found was to double the area of the gauge.

a 26g wire is 0.1288mm2 so joining them will double the area to 0.2576mm2, and closest gauge to that area is 23 with area of 0.2582 and a thickness of 0.57mm. But measuring my twisted wire with digital caliper it says 0.75, either something is way off, or you cant measure a twisted wire like that? maybe this calculation is if you just melt them together to a higher mass?
and I should trust the area calc.

Would like some Ideas on this

Thicker wire indeed has more mass compared to its area, while twisted wires don't. Cross section of a wire increases at the square of diameter, surface area linearly with diameter.

There are differences in the functional surface area, just as with different builds can have a different effect with the same heat flux.

Wire cross sectional area calculation
The n gauge wire's cross sercional area An in square millimeters (mm2) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm):

An (mm2) = (π/4)×dn2 = 0.012668 mm2 × 92(36-n)/19.5

This I found, but my math degree do not allow me to understand this whole formula

26g wire is 0.405mm and 0.1288mm2. somewhere in here you should be able to calc a cross wire gauge outcome i believe? And is this formula just for 2 wires? if so, how to change this to any amount you'd like?

twisting 2 26g wires together ends up simulating a 26 gauge dual coil electrically.

yes probably, I may just leave this and just fiddle with it instead it seems. finding out by testing diff stuff instead, I am quite limited by my evic vtc mini atm, twisted 26g requires so much more power than single 26g, at 65w i have to press the button, wait 1-2s then blow out and cool the coil, THEN inhale to get a good vape So i reccon for a fast intense vape I will have to pump the wattage this mod cant really do. Maybe I just want it to do what it really cannot do at the moment And I am over analyzing stuff.

Gonna do a 28g twisted now, so how that goes. I know for a fact it is going to be a faster ramp up, but I'll se how it goes. Seens I have to get the rx200 to play with the high gauge wires

if you use the link to Steam Engine, you can specify 26G, then twisted... It will ask for the pitch which is calculated by "The distance between each "ridge" on the twisted wire. Use 0 for non-twisted wire (parallel strands). For improved accuracy: Count 10 ridges, measure their total width, and divide by 10". This will get you VERY close to what your coils will Ohm out to.
