About This Chapter
Pressure, Fluid Flow & Buoyancy - Chapter Summary
If you need to quickly review the basics of pressure, fluid flow and buoyancy, you're in the right place. This convenient online chapter contains engaging and simple video lessons that cover pressure conversions, buoyancy calculations, the Venturi effect and other related principles. Upon completion of the chapter, you should be able to:
- Recognize pressure units
- Make hydrostatic pressure calculations
- Use Archimedes' principle to calculate force and density
- Explain Pascal's principle and Bernoulli's principle
- Describe the Venturi effect
The chapter's flexible online format allows you to study at any time that fits your schedule. Following each lesson is a short quiz to help you reinforce your understanding of key terms and concepts. Take the chapter exam to make sure you fully understand the material, and submit questions to our instructors if you have any.
1. Pressure: Definition, Units, and Conversions
Have you ever wondered what pressure is and how it gets measured? In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure.
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. 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.
5. What is Pascal's Principle?
Feeling pressured to learn about Pascal's principle? Then you came to the right place. Pascal's principle states that a change in pressure at any point in an enclosed fluid is transmitted equally throughout that fluid. See examples and learn more.
6. The Venturi Effect and Blood Flow
Blood flows through the body in a specific way, and in general, we want that to continue happening. So, understanding the Venturi effect is important. We will examine how, where, and why this occurs in the body.
