Someone asked me if we take into the account the weight of air in the plane- as in a highly pressurized scenario. Obviously we don't, but do you think there actually is even a small increase in weight if the air inside is denser than out? I would think there would be some, as in a full tank of gas like LP weighs more than an empty.

Thoughts?
 
Even more odd....

http://discovermagazine.com/2007/ju...?searchterm=how much does the internet%weigh?

I doubt the weight of the press. air significant enough to even amount to anything even approaching that of a dead rat under the floor.

Here's an even more odd one...... How much does the internet weigh? Not the equipment to transmit stuff, but the weight of all the electrons which collectively make it up.

-Hint-
There really is an answer-it is surprising.

OK-I am a nerd-but this was pretty neat!

I read or heard somewhere that the air inside a 747 weighs about a thousand pounds.

I did some googling and found this: [SIZE=-1]1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs.

So, a little math and you'll have your answer.

I also googled "weight of the internet." Turns out I'm a nerd too.

Since the density of the air in a pressurized aircraft is not going to be more than at SL, and unless they started weighing aircraft in a vaccum, the air inside is included in the BEW/BOW.

Or you could just tell them that the treadmill helps overcome the weight of the air.

William Blake’s famous poem Auguries of Innocence (1803) begins, “To see a world in a grain of sand....” He was being more prophetic than he could have ever known.


Some guys (like Billy) are just ahead of their time!

Sometimes a nerd too...
