Important!: Mathematics of Scuba Diving!

[simbrooks]

Math and scuba? OK, Ok....hmmmm
Here we go.... Johnny spends $1200 on a scuba system and another $700 on a guys trip to Honduras. While there, he spends another $150 on a Nitrox course and buys a new mask for $70. Meanwhile his wife wanted a new dinette set. So the question is ....
If he is 6'2", how much rope will she need to dangle him from a 10 foot ceiling? (Let's assume he is barefoot) <Jeopardy music in background>

Ooohhhh, i know this one, total length 5ft, enough to give him a bit of elasticity, but she needs some in there to tie a securing knot at the ceiling and a noose at the end, otherwise i would say maximum clear length 3' which is just short enough that he cant touch the floor on tip toes and can "bounce" a bit on the rope's elasticity. Of course if he spends just a little over $2k on a nice vacation for her with the girls or jewelry then this situation may not occur

Hey everybody, I am doing a project for my math class about the mathematics of scuba diving, but the thing is that I'm new to scuba diving don't have a great knowledge of it.
Can you guys tell me about how math is involved in scuba diving? How does math tie in with scuba diving? This is very important, and if I could get this info as soon as possible that'd be great! Thanks very much!

Hi Wilson

You can find more about this by looking into a few things.

Some of the relevant laws of physics for scuba diving are. (gas laws) Boyle's law, Dalton's law, Henry's law, Charle's law and Archimedes principle (buoyancy), principles of heat energy transference (convection, conduction), light, refraction, sound and so forth. A quick look in a basic level scuba manual will give you some good starting points to start looking stuff up. Knowning the names of the gas laws will make searching easier.

Decompression theory also makes heavy use of mathematics. If you want to really impress your techers you can download a document with huge amounts of mind boggling formulas by clicking here

the ceiling is 120" from the floor, Johnny is 74" tall, leaving 46" from the top of his head to the ceiling. on average i would assume a 6'-2" mans inseem is 36", allowing for 4" of testicle stretch, i would say 80" of rope? :errrr:

When you start looking at some of the new decompress models the math gets pretty advanced. The RGBM for example needs an understanding of calculas to read:

Great guess Simbrroks, but incorrect and you did not phrase your answer in the form of a question!

I forgot to mention Johnny was castrated 4 years ago. Sorry.

I forgot the jeopardy part, "what is being the diver married to a diving widow?"
