newbie here, ive been searching many forums and cannot find the questions/answers im looking for (close, but not quite). so, im going to ask my question in a very specific, detailed manner. i want to use nichrome wire to make 8 heating elements. they will each be a single strand running alongside the 8 injector lines of my diesel engine. their purpose is to heat the fuel (vegetable oil, in my case) in the lines. i understand ohms law, but that only deals specifically with amps, volts, ohms, and watts. my question is, is it possible to predict and achieve a target temperature range? in my case that range would be around 250* to 300*F. ultimately, my dilemma is particularly what gauge/resistance wire i should use, or if it makes no difference. in other forums i have read about people doing this, and their target wattage is in the neighborhood of 80 to 100W. i guess a better way to ask the question would be... will a certain wattage (for sake of arguement, 100W) give the same temperature, regardless of the makeup of the wire itself? i realize that the temperature would vary depending on the conditions surrounding the element, i.e. ambient temp, air flow, the heatsink effect from the fuel lines, etc. so, lets assume that the bare wire would be in open, still air at room temp. that should be a good starting point for me, i can probably adjust from there.
