Trivia Question: Where Would You Be At 1/2 Ata?

[DeepTechScuba]

Here is a trivia question that will keep your mind sharp and clear on absolute pressure, atmospheric pressure, and ambient pressure:

WHERE IN THE WORLD WOULD YOU BE IF THE ABSOLUTE PRESSURE WAS 1/2 ATA?

Clue:

First look in the NOAA DIVING MANUAL.

Then look in the World Almanac.

There are 7 correct answers.

 

[Walter]

18,000 ft altitude

One atmosphere "absolute" is sea level, isn't it?

If your down one atmoshpere under water it's two absolute.

What are the other six answers because, unless it's a trick question, you'd be (as Walter said) up in the air

Wait...I get the trick. You asked "where in the world". Are you looking for the names of seven mountains......

[ScubaTexan]

The top of Mount Everest??

 

[Walter]

"Are you looking for the names of seven mountains......"

I thought of that, but it wouldn't be a complete answer.

 

[ScubaTexan]

Walter once bubbled...
18,000 ft altitude

Couldn't be Mount Everest then, because it's over 29,000 feet altitude...

On everest you would be 2/3 the way up looking for your O2 bottle.
McKinley is at 20k.
Actually there are more than 7 mountains over 18k.

 

[Walter]

"Couldn't be Mount Everest then, because it's over 29,000 feet altitude..."

Barely over. Actually there's a story that Everest is exactly 29,000 feet, but since the surveyor didn't think anyone would believe such an even number, he added the other 28 ft. I don't know if the story is true, but it's a good story, none the less.

I'm pretty sure it's a bit over 29K. They used GPS to get a precise measurement some years back. I have the info at home in a book called "Into Thin Air" by John Krakuer (sp?). It's one of the best adventure books I've ever read, if anyone's interested. It's kind of like The Last Dive for mountain climbers.
