Not that guy, look at his graph here. Which he posted to support his claim when challenged by (paraphrased simply); "ok more nitrogen comes out at first, but there isn't a lot of it dissolved, so it will quickly run out". Which is very valid reasoning (as he proves himself) The horizontal...

:rolleyes:

Your reasoning is followed fine, it's just full of flaws. Flawed assumptions you have made; -All gas released during a pour stays trapped in the head. -Calculating diffusion rates in a sealed container when those conditions do not match real conditions. -The core assumption that it's...

:onestar:

That's my point. I don't claim to know all the conditions that contribute to the forming of the head. What I do know and have been arguing is that it is not as simple as a SS solution moving to equilibrium. And even if it was, the reasoning behind his conclusion under that premise is wrong to...

I don't, I take issue with the misapplication of principles, and the poor control of variables. It's an easily understood equivalent. If I can explain to a person that their diatribe is contradicted by basic logic, they should immediately review their statements and address that logic...

Except that I do, you are equating keeping a discussion simple as ignorance, which is a flaw in your own character. Again, the diffusion of gas under 3 atmospheres of beer gas is irrelevant to beer in a glass under 1 atmosphere of mostly nitrogen and oxygen, and essentially void of co2. That...

No, I choose not to get into what is not relevant. It does not matter what the contents of a bubble under pressure inside of the keg or under pressure in a syringe are. I even conceded to you that possibly some bubbles might contain mostly nitrogen, but this is not relevant to the context. It...

I am not speaking of intuition I am speaking of experimental results. Again, try dissolving nitrogen in beer, you will get effectively zero head, and that would be from beer with a greater content of dissolved nitrogen. Repeating "physics says" is a response of no value, and a poor rebuttal...

OK, but there's basically no nitrogen to make many bubbles. If you actually try to dissolve pure nitrogen in beer/water etc, you get basically no bubbles, you would barely get any observable head and the beer would taste completely flat. Knowing that, to say the bubbles will be mostly nitrogen...

I'm still really confused as to how you can say there is almost no nitrogen dissolved in the beer, yet the bubbles will form mostly full of nitrogen.

Yea, what I was thinking was how the 3 phase waves overlap vs single phase, but then after about 10 more second of thinking I realized that didn't change anything.

Thanks, that's pretty much what I'm looking for. 3 phase elements are just 3 single phase elements stuck into one package. I know they can just be wired by ganging the 6 terminals into two (3/3), not sure if there's a output loss though since 3 phase has some overlap

Has anyone seen an immersion heater with a triclover fitting in the 15kw range? Can't seem to find one and don't want to use multiples. (yes I need that big for something)

Not really, yours is just a problem of low settling rate, which is solved by adjustments. You have P and I on and if the settings are not optimal, what you described will, appropriately, happen. It's likely your problem will be adequately solved by mucking with the integral. I don't mind you...

Op is me, tungsten has a piggyback problem and is trying to steal my thread :tank: (my reply to augiedoggy before explains it)

I was really confused for a bit, I was like, this guy seems to know his stuff, wait... what did he say that's completely backw..... ohhhhh.

You gone and done it now, he doesn't like it when you do that. :mug: P.S. I figured it was something like this when you said integral is there to bring down the overshoot.

Wait, what problem are you talking about. The problem that created this thread was that my controller was choosing to heat past the SV even with I and D off, which is contrary to proper function. I mean I can tell you setting I to 1 effects better control than the default 240, and in fact...

There are applications of PID control for cooling, so you can't say it's correct in general, but it's definitely the context of this thread. He also said; When if anything (in heating), I is responsible for the overshoot in the first place, but if you translate it as speaking from a cooling...
