4b Flashcards
behavior of fluids, which is relevant to the functioning of the pulmonary and circulatory systems
1
Q
importance of fluids for the circulation of blood, gas movement, and gas exchange
A
- fluids are featured in many important processes such as circulation of blood, gas movement, and gas exchange with the blood
- energy requirements required to move fluids can be modeled using physics equations
- content:
~ hydrostatic pressure
~ fluid flow rates
~ viscosity
~ kinetic molecular theory of gases
~ ideal gas law
2
Q
fluids
phys
A
- density, specific gravity
- buoyancy, archimedes’ principle
- hydrostatic pressure
~ pascal’s law
~ hydrostatic pressure; P = ρgh (pressure vs. depth) - viscosity: poiseuille flow
- continuity equation (A * v = constant)
- concept of turbulence at high velocities
- surface tension
- bernoulli’s equation
- venturi effect, pitot tube
3
Q
circulatory system
bio
A
- arterial and venous systems; pressure and flow characteristics
4
Q
gas phase
gen chem, phys
A
- absolute temp, K, kelvin scale
- pressure, simple mercury barometer
- molar volume at 0ºC and 1 atm = 22.4 L/mol
- ideal gas
~ definition
~ ideal gas law: PV = nRT
~ boyle’s law: PV = constant
~ charles’ law: V/T = constant
~ avogadro’s law: V/n = constant - kinetic molecular theory of gases
~ heat capacity at constant volume and at constant pressure (phys)
~ boltzmann’s constant (phys) - deviation of real gas behavior from ideal gas law
~ qualitative
~ quantative (van der waals’ equation) - partial pressure, mole fraction
- dalton’s law relating partial pressure to composition
