Study Notes
Fluid Dynamics
- A fluid is a substance that can flow
- Fluids include liquids, gases, plasmas, and some solids
- Viscosity is the resistance a fluid has to flow. Higher viscosity means greater resistance
- Viscosity depends on temperature and intermolecular forces
- Fluid friction is the resistance between adjacent layers of a fluid
- Drag force is a retarding force on an object moving through a fluid
- Terminal velocity is the constant maximum speed of an object falling through a fluid. This occurs when the drag force equals weight
- Streamline flow, steady flow, or laminar flow occurs when each fluid particle follows the identical path as previously passed particles
- Turbulent flow has whirlpool-like regions, it is not smooth
