Laws For Diving

Question 1

Daltons Law?

PP=DA X .%
DA=PP/.%
%=PP/DA

Answer 1

The total pressure exerted by a mixture of gas is equal to the sum of the pressures of each of the different gases making up the mixture. With each gas acting as if it alone was present and occupied the total volume.

Partial Pressures= Decimal Percentage x Pressure

Question 2

Henry’s law states?
1bar= 1litre gas solution
2bar= 2 litre gas solution

Answer 2

At a given temperature, the amount of any given gas will dissolve in a liquid is directly proportional to the partial pressure of the gas.

Question 3

Charles Law states?
P1T1=P2T2

Answer 3

The volume of a given mass of gas’s at a constant pressure varies directly proportional to the absolute temperature

Question 4

Archimedes Principal states?
U= V X D

Answer 4

An object wholly or partially immersed in a fluid is bouyed up by a force equal to the weight of the liquid displaced by the object

Question 5

Boyles Law
P1V1=P2V2

Answer 5

At a constant temperature the volume of a fixed mass of gas is inversely proportional to the absolute pressure
