Study Notes
Definition and Scope
- Fluid mechanics is the study of the behavior of fluids under various forces and conditions
- It is a branch of physics that deals with the motion of fluids and the forces that act upon them
- It is an interdisciplinary field that combines concepts from physics, mathematics, and engineering
Key Concepts
- Fluid: A substance that flows and has no fixed shape
- Pressure: Force per unit area exerted by a fluid on a surface
- Density: Mass per unit volume of a fluid
- Viscosity: Measure of a fluid's resistance to flow
- Buoyancy: Upward force exerted on an object by a fluid due to density differences
- Laminar flow: Smooth, continuous flow of a fluid
- Turbulent flow: Chaotic, irregular flow of a fluid
Types of Fluid Flow
-
Laminar flow: Streamlined flow with no eddies or swirls
- Characterized by smooth, parallel streamlines
- Occurs at low velocities and high viscosities
-
Turbulent flow: Chaotic flow with eddies and swirls
- Characterized by irregular, non-parallel streamlines
- Occurs at high velocities and low viscosities
-
Transient flow: Flow that changes with time
- Can be laminar or turbulent
- Occurs in systems with changing boundary conditions
Bernoulli's Principle
- States that the pressure of a fluid decreases as its velocity increases
- Mathematically represented by: P + 1/2ρv^2 + ρgy = constant
- Where P is pressure, ρ is density, v is velocity, g is acceleration due to gravity, and y is height
Applications of Fluid Mechanics
- Aerodynamics: Study of air and gas flow around objects
- Hydrodynamics: Study of water flow around objects
- Hydraulics: Study of fluid flow in pipes and channels
- Oceanography: Study of ocean currents and waves
- Biological systems: Study of blood flow, respiratory systems, and other biological fluids
