All you are saying is BLAH BLAH BLAH..
All this really shows is you don't know when you've lost an argument.
fact is airflow has not one damn thing to do with how much heat a coil build generates.
Fact is you were talking about the warmth of the vape, not the heat a coil build generates. Heat generation is expressed in watts (i.e. not in degrees Celsius nor Fahrenheit), as the heat is simply power converted to heat, and, the
First Law Of Thermodynamics dictates energy can be neither created nor destroyed, therefore heat equals power in EVERY coil build, whereas temperature, although related of course, is nowhere nearly the same as heat.
You adjust the airflow to adjust the vape temperature and density not the heat flux of the coil.
Strawman argument. I never claimed that the heat flux of the coil can be adjusted by adjusting airflow.
If your heat flux is to low you dont generate any vape to cool in the first place.
So what's your point? Heat flux is determined by the total surface area of he coil, as the coil's surface is where heat is transferred into the juice, which also explains why the rate at which heat is transferred into the juice is determined by surface temperature in cohort with heat flux in cohort with airflow in cohort with the rate at which the juice is evaporated.
If you want more vapor you make a hotter running coil, airflow only cools the vapor, it does NOTHING toward producing the vapor.
Incorrect. Airflow also cools the coil's surface via the boiling juice that sizzles on top of that same surface, i.e., because increased airflow also causes the rate at which the juice evaporates to be increased, the fact faster evaporation causes faster cooling of the liquid surface from which the evaporation happens, also implies there will be additional cooling of the coil's surface that's located underneath this same liquid surface. This is all simple thermodynamics at the high school level of physics. Kids barely at the age of 15 are being taught all of this by their physics teachers all the time.
Its like adding sugar to your tea.. you like it sweet add more sugar, but that has nothing to do with making the tea in the first place.
Your wire type has nothing to do with the temperature, it is still volts and ohm.
Incorrect. While it is true the fact the watts on a mech mod are the volts multiplied by amps, the metal type of the wire does have a noticeable impact on the rate at which the temperature will be changing (i.e. the ramp up time with regards to the power output, and also the cool down time), as that is determined by what's known as
heat capacity.
The fact that stainless steel has lower resistance than kanthal has nothing to do with it, you factor that in when calculating your resistance/watts. The material of the coil has nothing to do with it.
I was not talking about the resistance. The ramp up time can have a very significant effect on how the vape feels (and tastes) so, for reasons that should be completely obvious to someone who claims to be familiar with mech mods, it also closely relates to the OP's description of "weak".
It doesnt. I already explained why not.
Since 0.25 ohm build on kanthal generates the same wattage as 0.25 build on stainless steel.
It does. But that has got nothing to do with Ohm's Law, as Ohm's Law isn't about watts... the watt is named after the Scottish inventor James Watt; this unit was proposed initially by C. William Siemens in August 1882 in his President's Address to the Fifty-Second Congress of the British Association for the Advancement of Science, i.e. some 28 years after Georg Simon Ohm died.
The difference is in how many watts is required to generate the heat on each coil.
Again, the generation of heat is expressed as watts, i.e. the amount of heat is precisely the same as the amount of power, and, temperature is not the same as heat.
The difference is, since SS has more mass at 0.25ohm than kanthal, you need more watts to generate the heat to run it. To get more watts you add more volts or reduce the resistance.
The mass is essentially irrelevant in coil building, only the volume is not. The volume is determined by the thickness (or better said, the surface area of the cross section) and length of each wire, and, the heat capacity of the coil (as calculated by Wire Wizard on the Steam Engine website) is determined by both the volumetric heat capacity of the chosen metal type and the volume of the coil. The volumetric heat capacity (VHC, also known as volume-specific heat capacity) of a metal type can easily be calculated, as it equals the
specific heat (also commonly referred to as the heat capacity of the metal type) multiplied by the density of the metal type. Density is unit mass per unit volume so you could argue that the mass actually does matter after all, but my point is you can simply look up both the specific heat and the density in the datasheet of the metal type so you don't need to know anything about the mass to be able to calculate everything you need.
As far as I can see, all you are doing is being contrary and over complicating a simple matter.
The only thing that is being contrary and overcomplicating here is your own ill-informed logic. Not just as far as I can see, but much, MUCH farther than that...
Determine how warm you like your vape, how many watts you need to generate that amount of warmth,
Can't really be done without delving into at least some added specifics such as draw strength/restrictiveness of airflow and the relationship between it and the speed of vapor production. Too much generalization and oversimplification is always a recipe for erroneous fake answers.
and the resistance of your coil at 3.7V to generate the required watts. And how is this done.. By using ohms law.
3.7V is just the nominal voltage of most batteries that are popular in vaping. You need to take the battery's voltage sag into account. No battery fires at 4.2V. That voltage is used to give you a bit of a safety margin when calculating the battery current. But nobody is saying the magnitude of the voltage sag will be equal to one half of a volt so, more often than not, the 3.7V that you mention will be nothing more than another really poor attempt at guessing all the numbers like usual.
Lets think about a cloud chasing build.. I build at 450 Mj/K to produce the vapor... THEN i add air to cool the vapor so I can inhale it. If you still want to insist that airflow has anything to do with vapor production, try sucking your atomizer without firing it and only using airflow. How much vapor do you get?
Every cloud chaser (that is, every SANE cloud chaser..) knows that restricting the airflow too much will be synonymous to losing the comp. That plus the fact I still have a 30mm Buddha V4 with a dual coil build of mine inside that will literally burn your mouth in not much longer than just a single small second if you fail to give it enough airflow, whereas if you suck on it really hard it will still be hot, but not too hot to handle, despite not everyone likes a draw requiring so much strength, and, as a matter of fact neither do I, but the reason why I built these coils was simply because I expected only to learn from how they perform, as a decent amount of trial and error is what puts me in the position of being able to talk from true experience rather than fuck people over with two boatloads of refined nonsense.
