Study Notes
Fluid Mechanics
- Fluid mechanics is the branch of physics that deals with the mechanics of fluids in motion.
Types of Fluid Flow
- Turbulent flow is characterized by irregular, chaotic patterns.
Terminal Velocity
- Terminal velocity is the constant speed at which an object falls through a fluid when the drag force equals the force of gravity.
Density
- Density measures the mass per unit volume of a fluid.
Viscosity
- The coefficient of viscosity measures the resistance of a fluid to shear stress or deformation.
Key Relationships
- The relationship between area and velocity in fluid dynamics is inversely proportional: an increase in area results in a decrease in velocity, and vice versa.
