Heavy Air

[bigheadfred]

Now hold on people. Surely all the global warming (co2)  and other pollutants have to play a role here.

The carbon alone has to count. It has to. I saw it on tv. I read it on the interwebs.

Was the "unsealed...opening to the "box" at the top (1 mile elevation), or the bottom (sea level)?? (Won't be "STP" at both points, so drop the "IOW" part and just say "1 cubic mile of air at STP"?).  Anyway, I tend to agree with "BiguN" on this one:

 "Just so you know, there are plenty of people here with the ability to answer the question but, it seems, no one thought it worth the effort.". 

Better to burn brain power on ideas to save the USA from a debt implosion, society's norms/morals unwinding, hyper-inflation, CW2 or something like that.

How unfortunate that so many people have such a lack of intellectual curiosity, especially AFTER I specifically stated, "The answer will astound you." Their/your loss.

Please post a list of threads where such "brain power" has been "burned."  Or something like that.

I think I have discovered our problem @DeerSlayer.  Your question was "what is the mass..."  and I took that to mean weight when you were talking about the density.  But then why was your answer given in pounds?   

Mass and weight are interchangeable at earth's sea level.  Moving up or down some miles may change the weight as measured on a scale, but not the mass.

Just so you know, the answer I calculated (just over 11 billion pounds) was very close to the one you endorsed up thread. The difference likely is due to a rounding error in the .0807 number I used.

What an arrogant idea.  I got bored with silly mental exercises that accomplished nothing back in middle school.  I've spent a couple decades in engineering and construction projects in Power, Oil, Gas and PetroChem.  I solve problems that have real world impacts.

Masterfully done.  Masterfully.  Lunch on me.

What an arrogant idea. 

Life is fragile, handle with prayer

First you attack ME as "arrogant" when in fact what I did was present a fun challenge for people of good cheer.

Then you proselytize to everyone, forgetting about the  Scriptures' many admonitions which you so cavalierly violated.

Since you're so self-important and have no interest in anything I have to say, I'll put you on IGNORE.

Let's calm down a bit here.  It's a frivolous thread, and seven years old.  It certainly does not justify the snippiness being displayed.  Let's move on to something important.

What, exactly, "important" do we do around here?  I think Brain Candy such as this is very worthwhile as well as stimulating.

Please provide your own five most "important" posts. I'd certainly like to learn from you.

"It's a frivolous thread..."  Are you kidding me?  This website is frivolous.   What would be lost if it were to be terminated today? People come to places like this to jabber, and often on things far less interesting than what is illuminated in my discussion of five million tons of air per cubic mile.

More to the point, what would be lost if a single Member were to be terminated for insulting the intelligence of the rest of the Members?

I miss @thackney

I miss @thackney

He was good guy. I miss him too.

[IsailedawayfromFR]

I miss @thackney

A true engineer who disdained hyperbole but focused on data and problem solving, likely better at it then most of us engineers(me for sure).

Found him to be the Ted Cruz of debating engineering topics, so it was only foolish to challenge him.

He left when a troll particularly attacked him with prejudice.

Likely is now in semiretirement enjoying his nice island home when the floodwaters rise.

[Lando Lincoln]

I miss @thackney

Indeed. He offered smart and knowledgeable insight without the insufferable ego. I hope he is well.

I have many times heard the phrase mental masturbation but never thought I would see a prime example...............................until this thread.

THIS is "mental masturbation" - yours

You misunderstood the question.
I said "sea level."  I said "standard pressure," which is 14.7 pounds per square inch.
Yes, sometimes there are high pressure areas and low pressure areas but they are NOT caused by carbon dioxide or dust.

[DefiantMassRINO]

There are  a lot of variables, man.

moles or kilograms?

What's the temperature, humidity, and barometric pressure?

Is it a good air quality day, is it a smog day, a wild fire smoke day, and should I subtract any salt (salt air over the ocean) from my mass or weaight calculations?

Does Bideflation factor into this at all?  Will a mole or kilogram of air maintain its value over time?

 

Maybe my time would be better spent watching TMZ.

I try to help people like you and you don't even listen.
Standard Temperature and PRESSURE!    How many times do I have to tell you, 14.7 pounds per square inch.
It doesn't change.

 You'd be better off watching Wrestlemania.

Are we talking saturated air or dry air?  And what about the acentric factor of its components?  Air is a non-Newtonian fluid.  You will have to calculate compressibility factors for nitrogen, oxygen, and water vapor.

14.7 PSI - 12 PSI at 1 mile altitude times square inches in 1 square mile.
WHY do you insist on trying to look intelligent by bringing up things that are totally irrelevant?
"STP". Look it up.  Standard Temperature and Pressure.

[DefiantMassRINO]

inch and pounds are not metric ... don't most science nerds use metric units as measures for their science stuff?

I'm may be a moron, but I did have to endure two chemistry (+lab) classes and one physics (+lab) class.  We always used metric measures.

Like meteorology ... when I was kid, barometric pressure was measured in inches of mercury, with 30 inches as a baseline at sea level ... now, the barometer readings are given in millibars ... I have to find a millibar-to-inches online calculator so my old brain can understand.

The real world is not a sterile laboratory with controlled conditions.  Real world measurements are more complex becaused the real world is not a controlled laboratory.  That's why much theoretical science stuff that works in a lab, goes sideways in the real world.

For a nitwit, like myself, we need to explicity state the conditions of the test or experiment.  None of this "standard" this and "sea level" that and "pounds" stuff.

What we are really talking about is a controlled laboratory environment with controlled conditions.  So, we are really measuring a mass (and weight?) of gas in a laboratory under fixed conditions?

BTW I don't watch Wrestlemania.  The story lines and acting are terrible.

Units are basically arbitrary as long as what is being used is defined.
