Finding Specification for Heating Nichrome Wire

[Adi02]

hello,If anyone of you help me in finding specification(diameter of nichrome wire required) for a 2 m nichrome wire to heat up to 65 degree Celsius .Voltage applied is 12 v. I want to use it by coiling it to cylindrical mica sheet to make a smaller heating product.Temperature should not exceed 65.

The temperature of the wire will depend on the temperature of the surroundings and the rate of heat transfer. Best to over power it and use a thermostat than rely on equilibrium.

I think you will have to experiment. I did find a calculator online but it only works for >95C and a straight wire in free air.
