Okay so before I get torn to shreds let me say I am coming to the gurus for knowledge because I am severely lacking in it.
So here is what I am trying to do. I am trying to figure out how to control the temperature of a wire when coiled or wrapped around a small glass tube. I am using 32 gauge kenthal wire I believe the resistance is 13.75 ohms per foot. Let's say I am using a foot of it to keep it easy. I guess my question is: is there a way to calculate the amount of Power (watts?) it is going to take to heat the wire to a specific temperature range? Say between 320-430 degrees F?
Things I know I don't know:
Will the diameter of the thing it is wrapped around change the outcome? or is it just based on the length and resistance of the wire? ( I read some formulas about the cross sectional area is that the space in which it is wrapped length wise along the thing I am wrapping?) just wasn't exactly sure on this
Would there be a way to limit the voltage or wattage to get the wires to reach a certain temperature and stay at that temp? (for the most part I know there will be heat loss and stuff like that)
I am trying to do this as "mechanical" as possible I guess I mean to say I want to use the most simple things I can to accomplish desired effect even at the cost of some efficiency or complete accuracy.
Any and all tips and criticism is welcome, I know I do not know what I need to and I am humbly asking for help.
