Pressure is...
|
the force pushing directly on a given surface.
p=f/a 15A |
|
1 N/m2 =
|
1 Pascal (Pa)
15A |
|
1 millibar (mb)=
(metereologists use this term) |
100 Pa (normal atmospheric pressure is 1013 mb)
15A |
|
As you increase the area on which a force acts, the pressure exerted...
|
decreases.
15A |
|
Ocean water pressure is greater than lake water pressure because...
|
the salt in the water gives it greater density.
15A |
|
What is the term that describes the study of liquids and gases and the forces they exert?
|
Fluid mechanics
15A |
|
Pascal's principle...
|
Changes in pressure in a confined fluid are distributed equally in all directions throughout the fluid. 15B
|
|
Machines that use fluids to transmit or increase force are...
|
hydraulic machines.
15B |
|
Mechanical advatage for hydraulics formula...
|
MA = output force/input force
15B |
|
As blood goes to capillaries, blood pressure...
|
decreases.
15B |
|
Archimede's principle...
|
An immersed object is buoyed up by a force equal to the weight of the fluid displaced.
15B |
|
Specific gravity formula...
|
weight in air divided by weight in air-weight in water.
(archimemde's principle) 15B |
|
Bernoulli's principle...
|
pressure of a fluid decreases as its speed increases. This allows airplanes to lift off the ground. 15B
|
|
Boyle's Law...
|
p1v1=p2v2 (pressure and volume are inversely proportional - when one goes up the other goes down)
15C |
|
Charles's Law...
|
v1/t1=v2/t2
15C |
