When a force has caused a hydro or areodynamic system to move, it is how we measure the rate at which it flows.
What is flow rate
100
This is the weight of air pushing down on itself and the Earth's surface.
What is Atmospheric Pressure
100
It is the lower portion of the line, the part you measure, when looking at the volume of a liquid.
What is the meniscus?
100
It is when the fluid flows smoothly around an object and stays streamlined.
What is Laminar Flow.
100
This is any weight taken on or off loaded to change the density and buoyancy of a ship.
What is a Ballast?
200
Heat (energy source) is added to the matter to change it from solid, to liquid, to gas (moving molecules faster).
How does matter change states?
200
It is when gas particles get pushed closer together in a Pneumatic Fluids System.
What is Compression.
200
It is your mass divided by the force of gravity, and may change!
What is your weight?
200
After a turbulent flow path, a particle goes through resistance patterns, known as this.
What is drag?
200
It acts like a pump in a hydraulic system, forcing blood to flow in one direction around the human blood vessels.
What is the heart in the human circulatory system?
300
Removing heat from an object so it hardens and no longer is a liquid.
What is solidification?
300
This system will generally generate more power, be more controlled, and usually self-lubricates while harnessing the power of liquid fluids.
What is a Hydraulic System?
300
1, and we measure other substances floating ability against this number
What is the density of water?
300
It is when fluid molecules are attracted (stick) to each other (cohesion), or when the molecules are attracted to other molecules (adhesion) and the fluids moves at different rates.
What is Viscosity?
300
These chambers or tubes hold the fluids in both hydraulic and pneumatic systems, waiting for the piston to push them into action.
What is a cylinder?
400
The three principles are 1) Matter is composed of molecules and other particles 2) Particles are in constant motion 3) there is a force of attraction among all particles.
What is the Kinetic Molecular Theory?
400
This system will have a compressible gas and often have a delay to the start of power
What is a Pneumatic System?
400
You get the number if you divide an objects mass, by its volume, and you will know weather or not it floats or not
What is Density?
400
If you can't find volume with LXWXH, you could drop the object in water and measure how much it rises.
What is Displacement
400
This muscle acts like a compressor in a pneumatic system, but is inside your body pushing gas around!
What is the diaphragm in the respiratory system?
500
It is When the particles on the surface of a liquid are giving off more attraction then the ones in the middle of the liquid. Think about water striders!
What is surface tension?
500
This is the equation to figure out force on an object
What is Force equal to Pressure divided by Area?
500
4 Degree's Celsius. In most fluids, the density will increase with a temperature decrease (KMT). One of the random anomalous properties of water is how it has different property for density, and water will have a zone where life can survive the winter.
What temperature is water most dense?
500
A fluid will move faster, have its molecules further apart, be less viscous, and less dense when this it is added.
How does temperature effect fluids?
500
Introduction of exotic species along all the shipping lanes has led to competition for resources in our harbors and sea lanes with native species, and may lead to extinction of some sea creatures.
What affect does emptying ships ballast have on our fluids systems?
