Fluids
Particle Theory of Matter (ISTAMP)
§ All matter is made up of tiny particles
§ All particles are in constant motion
§ All particles of one substance are identical
§ Temperature affects the speed at which particles move
§ In liquids and solids, the particles are close together and have strong forces of attraction between them.
§ In gas, there are spaces in between the particles
HOW IT AFFECTS FLUIDS
○ Liquids can flow
§ Particles can overcome attraction and slide pass each other
○ Gas can Flow
§ Very quick
§ Very distant
§ Spreads out easily
○ Thermal expansion and contraction
§ When temperature increases in an object, particles move faster
§ When temperature decreases in an object, particles move slower
Thermometer shows temperature through expansion of liquid (mercury) within glass tube
Pressure
How much force is applied on a single unit of area
Latin P
P = force (N) / Surface Area (S)
Pascal (Pa) = N / m^2
Density
How much mass is contained within a single unit of volume
Greek letter rho
rho = mass/volume
Uses of Fluids
Transportation
Melt solids to transport in fluid form
Slurry
Mixture of solids and fluids
Archimedes
Buoyancy of an object is equivalent to the weight of the fluid that is displaced by it
Plimsoll line measures bouyancy
Temperature
Liquid
Hotter = Less Viscous
Gas
Hotter = More Viscous
Pascal
In a closed system
Pressure is distributed evenly
Push on other side of piston =force exterted on this side of piston multiplied by the area
Pneumatic Systems
System using pressurized gas to transmit force
