Flashcards in Doppler Deck (21):
fluid in a tube flows in response to a pressure difference at both ends.
the speed of something in a given direction
a flow with periodic variations
flow a flow of or relating to a phase or phases
flow of a continuous nature
a flow in which neighboring layers do not mix but flow at different velocities
viscous fluid with no shearing between adjacent layers; idealized w/out any mixing of particles of fluid.
flow layers of fluid are straight and parallel to each other; they slide over each other. The highest flow speed is at the center of the vessel.
random and chaotic flow pattern. Particles move at different speeds in different directions.
a dimensionless quantity that is used to help predict similar flow patterns in different fluid situations
a change in energy over time or space
energy that a body possesses by virtue of being in motion.
the continuous physical force exerted on or against an object by something in contact with it.
the movement of an object or mass that is caused by the pull of gravity.
Energy losses in circulation - inertia
the resistance of energy
Effects of a stenosis
causes a random and chaotic flow pattern
fluid moves against a pressure gradient from a point of low pressure to a point of high pressure
Pressure Flow Relationships
the greater the pressure difference, the greater the flow rate
the current through a conductor between two points is directly proportional to the potential difference across the two points.
the pressure exerted or transmitted by the fluid at rest.
