Study Notes
Fluid Mechanics
- Fluid is a substance that deforms continuously under the application of shear stress, no matter how small the stress may be.
- Fluids can be either liquids or gases.
- They do not maintain a fixed shape.
- They have the ability to flow.
What is Mechanics
- Mechanics is the study of motion and the forces that cause or prevent motion.
Fluid Static Properties
- Density is a fluid static property.
- Density is defined as the mass of fluid molecules per unit volume.
Objectives
- Demonstrate understanding of fluid static properties and fluid dynamic properties, and their applications.
- Apply formulas of density, pressure, Pascal's law, Buoyant Forces, continuity equation, and Bernoulli equation.
- Solve problems involving each of the above parameters.
