Fluid Dynamics Part 2

what is the relationship between kinetic and potential energy

inverse

what is the relationship between pressure gradient and resistance

proportional

what is the relationship between pressure gradient and volumetric flow

proportional

Pressure gradient is equal to

volumetric flow times resistance

If you increase velocity what happens to pressure

decreases

pulsatile flow

flow in the cardiovascular system

laminar flow

flow that moves in concentric layers

disturbed flow

flow that isn’t laminar

where is there typically turbulent flow

at the exit

what are entrance effects

changes in flow profile when entering smaller diameter tube

what are exit effects

changes in flow profile when entering a larger diameter tube

what happens in an entrance effect

flow velocity accelerates

what happens in exit effects

flow velocity decelerates

where are the slowest velocities in a vessel

at the wall

the steeper the parabola may cause there to be

no velocity at the vessel wall

where does flow decelerate

Along inner radius

where does flow accelerate

along outer radius

Reynolds number for turbulence

>2000

reynolds number for laminar

< 2000
