Fluid Systems
Pneumatic
gases
compressed
under pressure
natural gas
pros
safe
reasonable cost
examples
pneumatic nail gun
pneumatic wrench
Pascals Law
Keeping in pressure
must be fully sealed
pressure transmitted equally
example
closed water bottle
stress ball
pumps
moves fluids
bicycle pump
compresses air
increase in pressure
goes to lower pressure
Archimedes screw pump
raises water
high to low pressure
change in pressure
makes systems work
Hydraulic
liquid
under pressure
transmits a force
incompressible
multiplies force
piston
pascals law
hydraulic jacks
hydraulic lifts
natural hydraulic systems
sap in trees
sea stars
valves
control fluids
changes flow
changes direction
tap
toilet
fluid spills
oil spills on water
floats
less dense than water
clean up
booms
barriers
skimmers
pull up oil
sorbents
sponges
dispersants
breaks up oil
burning
burns the oil
bioremdiation
bacteria breaks down
comes from run offs
environmental impact
harms plants
marine animals eat oil
effects many animals
oil spills on land
similar cleaning methods
easier to clean
doesn't spread as much
more then oil is spilled
caused by run offs
