Fluid flow 

Pascals

________ principle if pressure is applied to an enclosed system it is transmitted undiminished in the system.

Streamlines

________ visualize the fluid flow, its tangent gives info.

Bernoullis principle

________ tells us that the sum of the pressures is constant.

Hagen Poiseuilles

________ law the change in pressure is proportional to the resistance of fluids.

internal friction

If there is no viscosity there will be no ________ between the fluid.

Turbulent flow

________: we have relatively circular streamlines and speed of the fluid is faster.

Medical relevance

________: RADIAL PULSE; due to periodicity of the heart cycle the changing pressure can be detected as palpitations at the arteries and also find out number of heartbeats.

Laminar flow

________: when the streamlines are parallel to each other.

Hydrostatic pressure

________: considering resting fluids, pressure due to the weight of a fluid.

Blood

________ and aid are considered to be fluids and the tubes are assumed to have rigid walls.

Stokes law

________ describes the movement of a spherical object in a viscous medium.

Stationary flow

________: the streamlines do not change at any point.

Static pressure

________: ratio of force exerted on a certain area.

Static pressure

ratio of force exerted on a certain area

Hydrostatic pressure

considering resting fluids, pressure due to the weight of a fluid

High pressure

low pressure, pressure at IV point is larger than atmospheric pressure so Hydrostatic pressure provides the pressure difference

Dynamic pressure

if a fluid is moving at certain speed it has kinetic energy, this pressure is the kinetic energy of a fluid with a given volume

Medical relevance

RADIAL PULSE; due to periodicity of the heart cycle the changing pressure can be detected as palpitations at the arteries and also find out number of heartbeats

Ideal fluids

viscosity = 0

a) Newtonian

constant viscosity

b) Non-Newtonian

not constant viscosity

Stationary flow

the streamlines do not change at any point

Laminar flow

when the streamlines are parallel to each other

Turbulent flow

we have relatively circular streamlines and speed of the fluid is faster
