BIOFLUID MECHANICS FINAL PAPER
TESTED QUESTIONS WITH VERIFIED
ANSWERS COMPLETE STUDY SHEET
●● Fluid
Answer: a substance that deforms continuously when subjected to a
shear force of any magnitude
●● can "fluid" and "liquid" be used interchangeably?
Answer: No, liquid is a phase
●● Concept of Continuum
Answer: The fluid behaves as a continuous medium and not a collection
of particles.
OR
The mean free paths of the molecules that make up the fluid are much
less than the dimensions of the container
●● Continuum
Answer: There are no "gaps" between molecules
- a macroscopic approach
- don't consider behavior of individual molecules
,●● When might the assumption of a continuum not be valid?
Answer: space or nanoscale
●● Density
Answer: mass per unit volume
●● Specific Gravity (SG)
Answer: a ratio of the density of a fluid to the density of liquid water at
some specified temperature and pressure
- unitless
●● If using water as a reference: SG < 1
Answer: fluid or object will float
●● If using water as a reference: SG > 1
Answer: fluid or object will sink
●● gc
Answer: allows for the conversion of mass-acceleration units to force
units.
lbmft/lbfs^2
, ●● Density, specific volume, specific gravity, and specific weight give
us an idea of How "______" a fluid is.
Answer: Heavy
●● Mechanics of Pressure
Answer: Is the normal force exerted on a plane surface immersed in a
fluid and is created when that surface in bombarded with fluid molecules
●● Mechanics of temperature
Answer: Is the measure of KE of the molecules
●● T or F: every molecule that bombards the surface exchanges
momentum with that surface
Answer: True
●● can the IG EOS ever be used to approximate properties for liquids?
Answer: No
●● When are gases considered Ideal Gases?
Answer: T > 2Tcritical and P < 10 MPa, then IG EOS can be used
●● What type of pressure is in the IG EOS?
