Scuba Forum / General / January 2005There is more air than water! Try Soaring
There is more air than water! Learn about gliding at the Soaring Society of America National Convention, Ontario, CA A desire to explore a very special portion of our world is shared by both divers and sailplane pilots, and not surprisingly, the correlation between people who enjoy both scuba and soaring (motorless flight) is extremely high. The 12,000 member Soaring Society of America brings its annual convention to the Ontario, CA Convention Center on February 10 - 12, 2005, open to the public from 9 a.m. to 5 p.m. Of special note is the Saturday evening Awards Banquet, featuring keynote speaker Mike Melvill, pilot of SpaceShipOne (which is licensed as a glider). This dinner is open to all with separate advanced ticket purchase. Glider pilots flying sailplanes are capable of incredible feats: World records include altitude of 49,009 feet, and a non-stop flight of over 1,600 miles. Being one with nature, and exploring a beautiful part of our world is not only diving, but soaring. For detailed information regarding the Soaring Society of America National Convention and to purchase tickets, visit www.ssa.org/convention or call 505-392-1177. > A desire to explore a very special portion of our world is shared by both > divers and sailplane pilots, and not surprisingly, the correlation between > people who enjoy both scuba and soaring (motorless flight) is extremely > high.

What are you going to do after your boring meetings, sniff cows? If I wasn't laughing so hard, I'd ream you for spamming. i love scuba diving in the water or lakes and it is so cool. >There is more air than water! Learn about gliding at the Soaring >Society of America National Convention, Ontario, CA When you suddenly run out of air while diving, you just swim to the surface. When you suddenly run out of air in a glider, they use DNA to id you.  Signaturedillon "When the French are against it, you know we can't be far wrong." - Adm.

Depends upon your definition of 'more'... If your definition of 'more' is which has the greater mass / weighs more, I would believe that you will find that there is 'more' water than air... Hmmm... Awh, hell, I'm bored... Let's do the calculations just for sh.ts and giggles... First, let's get us some known values... From http://www.mos.org/oceans/planet/features.html we get the following values: 71% of the Earth's surface is ocean... The average depth of the ocean is 12,200 ft... There is approximately 140,000,000 sq-miles of ocean... Various known values that everyone should know: The atmosphere weighs approximately 14.7 lbs at sea level... A cu-ft of water weights approximately 62.4 lbs... We'll ignore the fact that the mountains displace some of the air... We'll also ignore the salt in the water... Thus there is approximately 197,183,098 sq-miles of total surface on the planet... (140,000,000 / 0.71) Assuming 14.7 lbs per sq-in, this equates to a total of 11,636,365,594,386,677,760 lbs of air on the planet... 197,183,098 = total surface area of planet in sq-miles * 5,280^2 = total surface area of the planet in sq-ft * 12^2 = total surface area of the planet in sq-in * 14.7 = total weight of the air on the planet in lbs The weight of the water would be approximately 2,971,257,569,280,000,000,000 207,780,249,600,000,000,000 lbs... 140,000,000 = total water area of the planet in sq-miles * 5,280^2 = total water area of the planet in sq-ft * 12,200 = total volume of water of the planet in cu-ft * 62.4 = weight of total volume of water of the planet in lbs Thus, there is approximately 255 times more water than there is air on the planet... Yeah, I know that the rules for significant digits doesn't justify me carrying all those digits around in the calculations, but I wanted to, SO THERE !!! > > There is more air than water! > [quoted text clipped - 4 lines] > Hmmm... Awh, hell, I'm bored... Let's do the calculations just for sh.ts and > giggles... Sounds like a good enough reason to me. Or ... as they say in fishdom -- do it for the halibut ... > First, let's get us some known values... > From http://www.mos.org/oceans/planet/features.html we get the following [quoted text clipped - 9 lines] > We'll ignore the fact that the mountains displace some of the air... > We'll also ignore the salt in the water... Uh uh. If we are gonna be pedantic about it, how can we ignore the salt in the water??? http://www.tesarta.com/www/resources/library/weights.html Water (fresh): 62.4278 (precisely under the conditions stated) Water (sea; average): 64. Those are the figures per cubic foot. That's a difference of over 1.5722 lbs per cu foot! And you multiply it by 140,000,000 square miles of ocean at an average depth of 12,200 feet, you get <approximately <G>> 74,862,358,179,840,000,000,000,000,000,000 lbs A lot of pounds of water dare, King Fish. But that's not the only 'rithmetic error you made. :-) > The weight of the water would be approximately 2,971,257,569,280,000,000,000 > 207,780,249,600,000,000,000 lbs... Off by orders of magnitude. :-) > 140,000,000 = total water area of the planet in sq-miles > * 5,280^2 = total water area of the planet in sq-ft so far, so good! > * 12,200 = total volume of water of the planet in cu-ft This is the average DEPTH of the ocean in feet! > The average depth of the ocean is 12,200 ft... > * 62.4 = weight of total volume of water of the planet in lbs So, if you use YOUR fresh water figure, the weight of the water would come to: 297,125,756,928,000,000,000,000,000,000,000 lbs. :-) > Yeah, I know that the rules for significant digits doesn't justify me > carrying all those digits around in the calculations, but I wanted to, SO > THERE !!! Looks like you need to go back to your drawing board, not the significant digits, but on the ORDER OF MAGNITUDE of your numbers. :-) -- Bob. > > > There is more air than water! > > [quoted text clipped - 40 lines] > > 74,862,358,179,840,000,000,000,000,000,000 lbs Oooops 1. That should have been 74,862,358,179,840,000,000 :-)) > A lot of pounds of water dare, King Fish. > [quoted text clipped - 5 lines] > > Off by orders of magnitude. :-) I thought you had attached 207, ... at the end of the first number, which (see Ooops 2 below) was actually correct, to all the digits stated. :-) > > 140,000,000 = total water area of the planet in sq-miles > > * 5,280^2 = total water area of the planet in sq-ft [quoted text clipped - 12 lines] > > 297,125,756,928,000,000,000,000,000,000,000 lbs. :-) Ooops 2. That should have been 2.97125756928 times 10^21 2,971,257,569,280,000,000,000 Got carried away with the trailing zeros. :( > > Yeah, I know that the rules for significant digits doesn't justify me > > carrying all those digits around in the calculations, but I wanted > to, SO > > THERE !!! > > Looks like you need to go back to your drawing board, I did, and found my own "decimal place" errors in the weight of WATER. You were off by only 74,862,358,179,840,000,000 lbs, by forgetting the salt in sea water. <G> Didn't go through your AIR WEIGHT analysis. -- Bob.
