, Fluid Mechanics the study of fluids at rest and in motion
Fluid a substance that deforms continuously when subjected to a shear force of any
magnitude
can "fluid" and "liquid" be used interchangeably? No, liquid is a phase
Concept of Continuum 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 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? space or nanoscale
Density mass per unit volume
Specific Gravity (SG) 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 fluid or object will float
If using water as a reference: SG > 1 fluid or object will sink
gc allows for the conversion of mass-acceleration units to force units.
lbmft/lbfs^2
Density, specific volume, specific gravity, and specific Heavy
weight give us an idea of How "______" a fluid is.
Mechanics of Pressure 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 Is the measure of KE of the molecules
T or F: every molecule that bombards the surface True
exchanges momentum with that surface
can the IG EOS ever be used to approximate properties No
for liquids?
