Study Notes

Fluids

  • Fluids are materials that don't have a fixed shape and can flow, like liquids and gases.
  • Laminar flow is a smooth, consistent flow pattern.
  • Turbulent flow is an irregular, mixing flow pattern.

Particle Theory of Matter

  • Particles are constantly moving.
  • Particles attract each other.
  • Particles speed up when heated.
  • All matter is made of tiny particles.
  • Particles have spaces between them.

Viscosity

  • Viscosity is how easily a fluid's particles slide past each other.
  • A high viscosity means the particles resist movement.
  • A low viscosity means the particles move easily.

Flow Rate

  • Flow rate is the speed of fluid movement, measured in volume per unit of time (e.g., liters per second).

Viscosity and Flow Rate

  • Flow rate is largely determined by viscosity. Higher viscosity fluids have lower flow rates.

Cohesion

  • Cohesion is how strongly particles of a fluid attract each other.
  • Examples include liquids like caramel.

Adhesion

  • Adhesion is how strongly particles of one substance are attracted to particles of another substance.
  • Examples include adhesive glue.

Fluid Mechanics

  • Fluid mechanics is the study of fluids at rest and in motion.

Fluid Dynamics

  • Fluid dynamics is the study of fluids in motion.
  • It is divided into aerodynamics (study of gases in motion) and hydrodynamics (study of liquids in motion).

Aeronautics

  • Aeronautics is the study of flight.

Controlling Blood Flow

  • Blood clotting can vary, with either too much or too little clotting needing medical intervention to correct.
