gas laws?????

[eleven]

im relativly new to diving most of the diving i do is on hookah , i have just enrolled in a commercial dive coarse (adas 1 and 2 on rpl ) can anybody help me with gas laws?

Buy Dennis Graver's SCUBA Diving. It's available at Barnes & Noble and at Amazon. After you've studied them, ask questions here about what you do not understand.

Yes, but not unless you have specific questions.

http://en.wikipedia.org/wiki/Boyle's_Law
http://en.wikipedia.org/wiki/Dalton's_law
http://en.wikipedia.org/wiki/Charles'_Law


However, I would expect a course to teach you that which they mandate you learn.

I am ordering the book recommended by Walter. If Walter suggests it I am comfortable with it being the best.

#1 gass law for anyone who has to ride in elevators daily

Hi Eleven,
Here's a "silly" way that I remember the gas laws from my BOW course. I think I first read them in Dive Training Magazine

Boyles Law - "Bulging Boyle" - Volume is inverse to Pressure, "come up too fast and you'll be bulging in the wrong places"

Daltons Law - "Divided Dalton" - Sum of Partial pressures of a gas mix make up the overall pressure.."the overall pressure is "divided" between those in the mix"

Charles Law - "Cool Charlie" - Pressure is proportional to temperature (in a sealed container).."need to keep your tanks cool"

Henrys Law - "Hoorah Henry" - How a gas dissolves in a liquid with pressure ...Hooray Henrys have too much bubbly!

Dive safe and have fun!

Archimedies principal ??????

Average Archie?
Archies Archrival?
Anti Archie?

Archimedes Principle? That just screws me up! :06:

Charles' Law deals with temperature/volume relationships. It has no diving application, but is very useful in hot air ballooning.

Amonton's Law deals with temperature/pressure relationships.

I stand corrected :05: ..Charles Law is Volume vs Temperature for constant pressure, but letting a fixed volume of air get hot (like a very full Scuba tank in a car trunk on a hot day) will lead to an increase in pressure, and if left long enough, a big bang as the burst disk goes. An infrequent but definite problem if you wanted to dive with that particular tank
