### conduit | tube | hose:

Soaker hose
* are also effective at keeping water at the ground level which also reduces evaporation
  - flexible and can easily be wound down rows and around plants
* contain thousands of tiny holes allowing water to seep through.
* provide moisture to the root system while keeping foliage dry.

Inner tube
* Some inner tubes extend from mouths.
* are artifacts
  - mechanical devices

Klystron
* Most klystrons have to be actively cooled by refrigerated water or other means.
* modulate the velocities of emitted electrons.

Long tube
* Some long tubes carry oxygen
  - urine
  - connect mouths
  - extend from larynxes
* are hard to keep mechanically stiff and so flex under the weight of the lens.
* make collar bones.

Muscular tube
* Some muscular tubes carry food
* Some muscular tubes connect cavities
  - cervixes
  - nasal cavities
  - pharynxs
  - extend diaphragms
* connect kidneys.

### conduit | tube:

Pipe
* Identify the different types of pipes used with copper, cast iron, plastics, and carbon steel.
* Most pipes carry debris
  - heat
  - hot water
  - liquids
* Most pipes contain particulate matter
  - fill with water
  - have air chambers
* Some pipes carry flammable chemicals
  - waste
  - conduct electricity
  - consist of hollow pipes
  - know as tubules
  - transmit electricity
* are a commodity product generally used as a conduit to transmit liquids or gases
  - underutilized communication medium
* are an abstraction for filtering packets
  - ancient chinese ritual
  - conduits
  - containers
  - cylinders
  - earth-tone colored from golden tan through oranges, browns, reds, dark reds, and black
  - expensive to build so water becomes more expensive as a city grows
  - less likely to freeze if they're exposed to warm air
  - located in water fountains
  - made of metal
  - part of pipelines
  - used for smoke
  - very important items as their smoke was thought to carry prayers
  - wind instruments
* bring water.
* can vibration in three orthogonal directions just like a machine.
* connect to sources.
* contain matter
* deliver water to homes and businesses at a higher pressure than the air outside
* enter exterior walls
* freeze underground.
* go all the way down to where the water is in the ground.
  - places
* includes pipe bowls
  - readsides
  - sections
* run along walls.
* transport materials.
* using bellows occur in many parts of Europe, and in many forms in Britain.
+ Solar panel, Installation: Solar energy :: Heat :: Electricity
  * Solar panels for heat are usually made from a box with a clear window on top. Pipes run through the box. The pipes and the box are usually painted black because black absorbs more heat than other colors. The pipes are filled with a heat transfer fluid such as water or oil. A pump circulates the fluid, which heats up as it is exposed to the sun. When the hot fluid leaves the panel, it goes into a heat exchanger, which transfers the heat into water or air. After the now cool fluid leaves the heat exchanger, it is pumped back up into the panel to collect heat again.
+ Universal Serial Bus, How USB is done: Computer hardware
  * Pipes are connections from the host controller to a logical entity on the device named an endpoint. The term 'endpoint' is occasionally used to incorrectly refer to the pipe.

### conduit | tube | pipe:

Bagpipe
* are aerophones frequently used in some traditional music
  - located in pain
  - musical instruments
  - the original rock instruments
* are used for funerals
  - noise
  - play
  - woodwind instruments
* exist over much of Europe, the Middle East and North Africa.
* have a two thousand year history and can be found all across Europe and the Middle East
  - an air chamber in the form of a bag
  - and can be played at multi-ethnic weddings to the enjoyment of all
* play at only one volume level, that is, loud.
