comment Where can I find a table for NIST standards on temperature and pressure?
@pentane That's a really good link. I got to webbook.nist.gov/chemistry/fluid from there. I think my question could have been wrong — though it surprises me a bit. Dry air is not listed as one of the species. Perhaps there isn't an agreed upon standard for the composition of dry air. Which is kind of a bummer as a standard for the same is badly needed. And I don't suppose it's all that difficult to arrive at one. Typical constituents are more or less constant and publishing the results for a laundry list of experiments should be easy from thereon.

Yes I did. I couldn't find it. I also tried googling nist standard atmospheric pressure and temperature but none of the results are directly relevant. They have partial answers of my questions. I need one place where everything is listed.

comment Why doesn't a cigarette lighter generate thrust?
In essence if a sealed chamber with just one opening to the outside is created, the lighter will develop thrust, correct? Of course such a setup includes some way to supply oxygen into the chamber as well.

comment What does $σ$ equal to zero mean?
But FTs are mere sticks compared to the howitzers that LTs are. They obliterate the differentials for us to play with the remains. It just somehow makes me wish I could understand LTs a lot better than I do right now. (EDIT: not that FTs are any less important; on the contrary they are perhaps more widely used).

comment What does $σ$ equal to zero mean?
I don't think I have an intuition for Fourier transform either, but somehow it's much easier to keep in mind: Fourier transform finds and highlights the constituent frequencies of a time varying signal. And Fourier Transform is arrived at from Fourier series, which again is quite straight forward. I don't suppose I can truly understand these concepts — perhaps it is ludicrous for mortals to expect that they will arrive at Parseval's theorem intuitively. Even then, I rarely fumble around with FTs and FSsand hence I am fine with my limited perspective.

comment How to model an apartment's airconditioning?
Thanks for the answer, I upvoted it. But it's still not what I am looking for. I am looking for a more mathematical model (with elements like the heat exchange (i.e. the ac), the heat sink (i.e. the apartment) and the environment). A general model which can be used for a first-order approximation.
