Study Notes
Fluid Mechanics
- Fluid mechanics is the branch of physics that deals with the mechanics of fluids in motion.
Fluid Flow
- Turbulent flow is characterized by irregular, chaotic patterns.
Fluid Properties
- Density is the measure of the mass per unit volume of a fluid.
Fluid Dynamics
- Terminal velocity is the constant speed at which an object falls through a fluid when the drag force equals the force of gravity.
Fluid Flow around Objects
- As the area of the object in fluid flow increases, the velocity of the fluid around the object decreases.
