Boyles Law
|
k Temp Volume inversely proportional with pressure |
|
|
Charles Law
|
K Pressure Temp directly proportional with volume |
|
|
Gay-Lussacs Law
|
K Volume Pressure directly proportional with temp |
|
|
Daltons Law
|
Total pressure of gas is equal to sum of partial pressures
|
|
|
Henrys Law
|
Solubility of gases in a liquid. The amount of gas that dissolves in a liquid is directly proportional to the pressure of the gas.
|
|
|
The mole
|
6.02 x 10^23 particles 1 mole of gas at standard temp 0c and standard pressure (1atm) occupies a volume of 22.4 liters. Ex: how many liters is 0.5 moles of oxygen occupy = 11.2L |
|
|
VP of gases
|
Sevo-157 Iso-239 Des-669 |
|
|
Ficks
|
Gases diffuse from high concentration to low concentration- Larger the surface area the more the diffusion. The more soluble the more diffusion.
|
|
|
Grahams
|
Diffusion rate of gas. With T and P constant. The speed of diffusion is inversely proportional to the square roots of the molecular weights. The smaller it is the faster it will diffuse.
|
|
|
Daltons
|
The total pressure of a gas is the sum of the partial pressures
Ex: Air is 760mmhg, 21%O2760X.21=159.6 mmhg of pressure exerted by 02 |
|
|
How much o2 is dissolved in blood with pa02 300?
|
300x.003=0.9ml/100ml blood
|
|
|
What do you multiply the Pa02 by to calculate amount of oxygen dissolved in blood
|
0.003
|
|
|
How to calculate P02 estimate
|
Multiply Fi02 by 5 Ex: 50% Fi02x5=250PaO2 |
|
|
Given Fi02 calculate Pa02 and amount of 02 in blood.
|
Multiply Fio2 by 5=Pa02 then Multiply by 0.003= 02 in blood Ex: Fi02 is 50= 50x5=250Po2 250x0.003= 0.75ml/100ml blood |
|
|
Calculate C02 in blood
|
Multiply PaC02 by 0.067 EX: PaCo2 is 50= 50x0.067= 3.35ml/100ml blood |
|
|
If you take Iso and add to flask of oxygen, what is the percent o2 and percent Iso in flask above the liquid?
|
Vp of Iso/ Atmospheric pressure Ex: 239/760(mmhg)= 0.31 or 31% 100-31=69%O2 |
|
|
Freezing point of water in kalvin
|
273 K |
|
|
Bernoullis Principle
|
As the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases
|
|
|
Relative vs absolute humidity
|
Relative is a percentage
|
|
|
Specific gravity
|
SG= Mass of object/Mass Water
|
|
|
Farenheit to celcius
|
F=9/5c+32
|
|
|
Celsius to Farenheit
|
C=5/9(f-32)
|
|
|
Reynoulds number
|
Flow becomes turbulent >2000
|
|
|
Properties of gases
|
Compressible Expansive Low density Diffuse more rapidly than liquids No definite shape |
|
|
Absolute 0
|
Zero K
|
|
|
Rapid compression of gas
|
Heat builds up
|
|
|
Gas pressure
|
In a closed container the pressure increases as the temp increases |
|
|
Gas Density
|
The density of a gas is directly proportional to its molar weight
At a constant volume the density increases as the pressure increases. At a constant pressure the density will decrease as the temperature increase. |
|
|
Joule Thompson effect
|
Cooling effect. As molecules rapidly leave they take thermal energy with them |
|
|
Due Point
|
The concentration of water exceeds the solubility of water in air |
|
|
Ounces to Grams
|
1oz is 28.35g
|
|
|
LaPlaces Law
|
The larger the radius of the tube the greater the wall tension. The greater the pressure the greater the wall tension. ex: as an aneurysm gets bigger its more likely to rupture |
|
|
Avogradros Theory
|
At the same volume, pressure, and temp gases contain the same number of molecules
|
|
|
Molarity
|
Moles of solute/liters of solution
|
|
|
Molality
|
Moles of solute/Kg of solvent
|
|
|
What changes weight or mass
|
Weight
|
|
|
