Ch 39: Principles of Fluids

About This Chapter

Get ready to brush up on the behavior of fluids in the body with the lessons in this chapter. Our instructional videos, transcripts, and self-assessment quizzes build on the material you have studied and put a fresh spin on the subject.

Principles of Fluids - Chapter Summary

Watch our brief videos about the principles of fluids that relate to the pulmonary and circulatory systems. The lessons are taught by professionals who describe the fundamentals of pressure and the way fluids move in fun, practical ways. You will also examine the variables needed to solve equations that include pressure, speed and height. After studying this chapter you should feel confident about:

  • Calculating hydrostatic pressure
  • Pascal's principle
  • Working with fluid mass, flow rate, and the continuity equation
  • Bernoulli's principle and equation
  • Relating the Venturi effect to arterial and venous blood flow

Written transcripts follow each video so you can read along or re-read the material later to maximize your efforts. You can also pull up the highlighted terms and formulas in the transcripts to use as a quick reference tool.

Finish the lesson with a short quiz to test your mastery of fluids and determine which areas you might need to spend some more time on. Since our lessons can be accessed from any mobile device, you can turn any environment into a learning center with just the click of a button. With most videos taking only about 5-10 minutes to view, our portable lessons can save you time.

Hydrostatic Pressure: Definition, Equation, and Calculations

1. 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.

Applications of Pascal's Principle

2. Applications of Pascal's Principle

After watching this lesson, you should be able to explain what Pascal's principle is, including providing the equation that represents it. You should also be able to provide examples of Pascal's principle in action and solve problems using the equation.

Fluid Mass, Flow Rate and the Continuity Equation

3. 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.

Bernoulli's Principle: Definition and Examples

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.

Bernoulli's Equation: Formula, Examples & Problems

5. 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.

The Venturi Effect and Blood Flow

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.
