Science Flow Rate
The rate of flow of fluids
Question | Answer |
---|---|
Viscosity | a measure of how easily a fluid particles are able to silde past one another |
Fluids | materials that have no fixed shape and free to flow, such as liquids and gases |
Particle Theory Of Matter | a theory that helps explain what matter is made of |
Laminar Flow | a smooth pattern of flow |
Turbulent Flow | an irregular, mixing flow pattern |
Eddy | an area of slower-moving fluid that occurs behind an obstacle |
Streamlined | a smooth shape designed to decrease resistance to fluid flow |
Flow Rate | a measure of how quickly fluids move; measured in a volume per unit time |
Cohesion | a measure of how strongly the particles of a fluid attract each other |
Surface Tension | the strong attraction among the particles that form the surface of a liquid |
Adhesion | the attraction between the particles of a substance and the particles of another substance |
Fluid Mechanics | the study of fluid and how they behave when at rest and when moving |
Fluid Dynamics | a part of the study of fluid mechanics concerned with how fluids move |
Aerodynamics | a part of fluid dynamics concerned with how gases move |
Hydrodynamics | a part of fluid dynamics concerned with how liquids move |
Oxygen | releasing energy from food |
Blood | acts as a transport system to take materials to cells as well as gather wastes from cells |
Sweat | cools the body |
Saliva | lubricates food for swallowing and begins chemical digestion |
Urine | eliminates dissolved wastes from the body |
Stomach Acid | Aids chemical digestion of food |
State the particle theory | • all matter is made of tiny particles • particles have empty spaces between them • particles are moving randomly all the time • particles move faster and spread farther apart when they are heated • particles attract each other |
Factors of flow rate 1 | the type of fluid that is flowing (thin fluids flow faster than thick fluids) |
Factors of flow rate 2 | the force pushing on the fluid (stronger forces produce faster flow) rates) |
Factors of flow rate 3 | the size of the pipe or opening the fluid is flowing through (larger opening means lower flow rate) |
Factors of flow rate 4 | the type of surface over which the fluid is flowing (smooth surfaces allow for faster flow) |
