What's a fluid?5:15
Welcome to the course! In this introduction lesson we lay the foundations by defining a fluid.
Types of fluid models7:22
In this quick lesson we will be going through the models of fluids we use to classify and define fluid flow patterns.
Types of fluid flow patterns (Reynolds number)9:28
In this lesson we learn about fluid flow patterns, what it means to have laminar or turbulent flow. We also learn about the Reynolds number, what does it mean and represent and how it is calculated.
Reynolds number exercise9:10
In this lesson we do a calculation exercise to determine if the flow inside a pipe that transports milk is going to be laminar or turbulent. After this lesson there is homework and a quiz on the problem you have for homework.
Reynolds number homework
Rheological models of fluids8:39
You probably heard about the term "Newtonian fluids", in this lesson we will be learning what does that classification mean and a little bit of theory behind it.
Rheological classification9:34
Building upon the previous lesson, in this lesson we are talking about the various types of fluids in terms of rheology. Newtonian, Bingham plastic etc.
Fundamental laws used in fluid mechanics12:38
In this quick lesson we go over the fundamental laws in physics we are going to be using in fluid mechanics, such as Newton's laws of motion, conservation of mass etc...
First test

Molecular level5:59
Introduction lesson for section 2. In this lesson we will cover what happens on a molecular level when it comes to fluids and matter. We explore the micro structure of matter so we can get a deeper understanding what happens on a macro level.
Classification of physical properties3:52
In this quick lesson we are going to classify physical properties of fluids that we are going to cover in this section.
Pressure7:46
In this lesson we learn about the concept of pressure and we define different types of pressure when talking about measurements.
Measuring pressure part 110:06
In this lesson we cover the apparatus used for measuring pressure and we do a couple of quick exercises (problems) regarding calculating and measuring pressure. This is the first part in a two part lesson regarding measuring pressure.
Measuring pressure part 26:06
Building on the previous part, in this lesson we do some practical measurements and calculations.
Density10:21
In this lesson we talk about density and its relation with fluids. We also talk about the relationship between density and temperature.
Measuring density5:11
Learning how to measure density and talking about the materials that we covered in the last lesson will help students understand density and its relationships with other physical properties.
Compressibility7:50
In this lesson we learn about what actually means to compress something and we learn about the coefficient of compressibility/bulk modulus
Viscosity9:45
Building upon the previous lessons where we mentioned viscosity, we are going to talk about this important fluid property in depth. More of a recapitulation of our previous knowledge but yet still more information on viscosity.
Couette flow17:57
Building on the blocks we already laid in the previous lesson and section, we will compare solid bodies and fluids in terms of viscosity and deformation.
Surface tension part 111:13
In this lesson we will be learning about surface tension, a very interesting and often overlooked property of fluids. We will make a foundation for the next lesson in which we will learn about capillary action.
Surface tension part 212:26
Second part of the lesson on surface tension. In this lesson we will calculate what it takes to pop a bubble and we will discuss more about surface tension.
Capillary action8:25
In this lesson we see what capillary action is and we learn about adhesion and cohesion.
Calculating capillary action10:02
In this lesson we will go over the ways we can calculate the capillary action of a liquid, gas and solid medium.
Vapor pressure and cavitation5:57
The last lesson (for now) in the section on physical properties of fluids and the last lesson in this part of the course. Cavitation is one of the more important properties and phenomena in fluid mechanics. Check out the video in the resource part.

Description

Welcome to Fluid Mechanics Basics 1 - Introduction, where we turn the daunting topic of fluid mechanics into an exciting adventure! Picture this: mention “fluid mechanics” to students, and you'll likely see a mix of fear and confusion. But fear not! This course is designed to make the scary stuff vanish and transform the subject into something engaging and enjoyable.

In this course, we’ll embark on an exploration of the fundamentals of fluid mechanics, starting from square one. We'll define what fluids are, explore various types of fluid flow, and dive into the world of rheology, unraveling how fluids move and deform.

But there's more! We'll decipher the essential laws that govern fluid mechanics, shedding light on their applications and revealing the secrets behind fluid movements. And, of course, we'll delve into the intriguing physical properties of fluids, demystifying viscosity, density, and more.

The best part is that you don't have to know a lot to start learning about fluid mechanics, just bring enthusiasm with you and you are all set!

Join us in this journey of discovery. Together, we'll swap those fearful expressions for ones filled with fascination, unraveling the mysteries and making fluid mechanics an enjoyable exploration!

The course is divided into two sections:

Fundamental concepts
In which you will explore the fundamental concepts like what even is a fluid, what is rheology, flow types, classification of fluid types and more
Physical properties of fluids
In which you will be learning in depth about all of the physical properties of fluids that you will have to know in order to continue learning fluid mechanics deeper

Here's the best part: learning doesn’t have to be dull. We've woven humor and interactive elements into the course to banish the fears associated with fluid mechanics. By the end, you'll navigate these concepts with confidence, eagerly anticipating Fluid Mechanics Basics 2 - Statics.
