Ch 16: Fluid Mechanics in Physics

About This Chapter

Watch video lessons on fluid mechanics to learn how gas or liquid substances respond to pressure and other forces. Each lesson is accompanied by a short multiple-choice quiz you can use to check your understanding of these fluid mechanics topics.

Fluid Mechanics - Chapter Summary and Learning Objectives

In this chapter, you'll learn about a branch of physics that examines fluids, such as gases, liquids and plasmas, and the forces or mechanics that act upon them. The instructor will explain how mass, pressure and volume affect fluids at rest or in motion, as well as how to measure these mathematical relationships. You'll also find out how to calculate the movements of fluids.

As you progress through the videos, you can learn about the impact of gravity on fluids and become acquainted with several important equations, including one that can help you determine the speed of a flowing fluid. When you have completed this video series, you should be able to:

  • Identify fluids and how they respond to specific forces, such as gravity
  • Discuss, calculate and convert among units of pressure
  • Explain and calculate the buoyancy of a material object partially or fully immersed in water
  • Define and use an equation to determine flow rate

4. 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.

Buoyancy: Calculating Force and Density with Archimedes' Principle

5. 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.

Fluid Mass, Flow Rate and the Continuity Equation

6. 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

7. 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

8. 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.

Torricelli's Theorem: Tank Experiment, Formula and Examples

9. Torricelli's Theorem: Tank Experiment, Formula and Examples

Torricelli's theorem has practical applications in everyday life. This physical law explains an important relationship between fluid exit velocity and the height of that fluid in a container. Here, you will learn about this relationship as well as see how to calculate exit velocity using Torricelli's theorem.
