How much energy to heat up my coil?

[oplholik]

Is there someplace in Steam Engine, coil builds, that shows how much energy it takes to heat up a particular coil?
For instance, if I wrap a single coil with 29g Kanthal, 1.5mm dia., 12 wraps for,1.42Ω, and another coil with 30g Kanthal, 2.0mm dia., 6 wraps for 1.5Ω, I would like to know the difference in the amount of energy used between the two coils. Thanks.

Thanks edyle.

Ok, if I'm looking at the right place, I see mj/K. next to it on the left I see 8.76 for the 30g coil, and 13.93 for the 29g coil. That seems to me a substantial difference in energy.
I normally wrap the 30g for my RM2's on my Reos Grands, but I am trying to get a coil length that is closer to the width between the post holes, if you know what I mean, and I don't want to make it much harder on the batteries to heat all that extra coil up.
What I have been using works, but looks crappy by the time I spread the legs out to get them thru the post holes.

adjust the ID diameter instead.

or use a spaced coil

theres a trick i saw for making a perfect spaced coil by using a paperclip.......

Go to the Battery tab, enter your ohms and read results.... Shows watts and amps per volts, also shows estimated number of hits and number of vaping minutes. Use this wattage number in the watts box on the coil building tab.

Thanks 93.
