Dive Laws Flashcards
What is Charles/Gay-Lussac’s law?
Charles/Gay-Lussac’s law states that at a constant pressure the volume of gas is directly proportional to the change in absolute temperature.
What is Boyle’s Law
Boyle’s law states that at constant temperature, the absolute pressure and the volume of gas are inversely proportional.
What is Dalton’s law?
The total pressure of a mixture of gasses is equal to the sum of the pressure of each of the different gasses making up the mixture, with each gas acting as if it alone was present and occupied the total volume.
What is Henry’s Law?
The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of that gas
What is Archimedes principle?
Any object wholly or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object
What factors affect (naturally) buoyancy?
Body fat
Body weight
Lung capacity
Bone structure
What does boyles law relate to?
S.P.A.M.
Squeezes
POIS
Air consumption
Minimum Manifold pressure
How does Dalton’s relate to diving?
Nitrogen narcosis
O2 toxicity
Decompression tables- PP of gasses determines the decompression tables along with Henry’s law
How does Henry’s law relate to diving?
Deeper you go, the more gas you absorb. PP increases, body absorbs and takes longer to off gas
How does Charles/Guy-Lussac’s law relate to diving?
CAR
Charging
Air in stowage
Recompression chamber operations
