About This Chapter
Praxis Physics: Fluid Mechanics - Chapter Summary
These lessons serve to review specifics of fluid mechanics as a step in your studies for the Praxis Physics exam. This chapter will address the following aspects of fluid mechanics:
- Characteristics of fluid in physics
- Calculations of hydrostatic pressure
- Archimedes' Principle
- Continuity equation, flow rate, and fluid mass
- Bernoulli's principle and Bernoulli's equation
Accompanying each brief video lesson is a full transcript that highlights key terminology that will aid your studies of this subject. After you complete each lesson, you may take the accompanying self-assessment quiz to determine how much you remember about what you've just reviewed. In addition, after you complete the entire chapter, you may take the cumulative chapter exam to gauge your comprehension of all the content covered.
1. Fluids in Physics: Definition and Characteristics
Fluids really know how to move! As flowing materials, fluids have some unique properties that help us understand and describe them. In this lesson you'll explore what fluids are and how they are defined in the world of physics.
2. Hydrostatic Pressure: Definition, Equation, and Calculations
This video lesson will introduce you to hydrostatic pressure in a liquid, as well as provide examples for how to calculate the liquid's pressure at a given depth.
3. Buoyancy: Calculating Force and Density with Archimedes' Principle
Knowledge of the buoyant force is important when trying to understand why some objects float while other objects sink. In this lesson you'll learn about this unique force and how we apply it to various situations using Archimedes' Principle.
4. Fluid Mass, Flow Rate and the Continuity Equation
Fluids rarely stay put, so we need to understand how they move. In this lesson, you will learn about how the movement of fluids is influenced by the space it passes through, as well as see examples of how to calculate aspects of this movement.
5. Bernoulli's Principle: Definition and Examples
Understanding how a moving fluid's speed and pressure change as it flows along is not only important for building airplanes but also for backyard fun. In this video lesson you'll learn about Bernoulli's principle and identify some practical applications of this concept.
6. Bernoulli's Equation: Formula, Examples & Problems
Bernoulli's equation describes an important relationship between pressure, speed, and height of an ideal fluid. In this lesson you will learn Bernoulli's equation, as well as see through an example how in an ideal fluid, the dynamics of that fluid remain constant.
