# Ch 10: Fluids in Physics

### About This Chapter

## Fluids in Physics - Chapter Summary and Learning Objectives

In this chapter, you'll examine characteristics of density and learn to convert among units of pressure. You'll learn to perform hydrostatic pressure calculations and apply Pascal's principle. Instructors will lead you through lessons on fluid mass, flow rate and Bernoulli's Principle. When you've watched all the lessons in this chapter, you'll be familiar with:

- Measurements for density
- Relationships between pressure, force and area
- Densities of solids and liquids
- Equation of continuity
- Formula for Bernoulli's equation

### 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. 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.

### 4. 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.

### 5. 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.

### 6. 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.

### 7. 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.
