# Ch 15: Fluid Dynamics in Physics

### About This Chapter

## Fluid Dynamics in Physics - Chapter Summary

This convenient online physics chapter examines basic fluid dynamics concepts. You'll study short, simple and entertaining lessons that cover fluid dynamics-related principles and equations. You'll also review specific gravity and hydrostatic pressure calculations. Our instructors are available to answer any questions you may have, and the chapter can be completed at your own pace. We've also made the chapter accessible on any computer or mobile device so you can study fluid dynamics in virtually any location that has access to the Internet. By the end of the chapter, you should be able to:

- Make specific gravity calculations
- Apply Archimedes' and Pascal's principles
- Make conversions between pressure units
- Use the hydrostatic pressure calculation
- Recognize the equations for fluid mass, flow rate and continuity

### 1. What is Specific Gravity? - Definition, Formula, Calculation & Examples

Why do some objects float while others sink? One of the factors that determines this is the density of the object. The density of an object is related to another important factor called specific gravity, which will be the main focus of this lesson.

### 2. 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.

### 3. 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.

### 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.

### 5. 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.

### 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.
