YouTube Lecture Series
The aim of Fluid Mechanics 101 is to teach fluid mechanics to everyone, all around the world. Hence, all of the lectures are free to watch on YouTube and can be enjoyed by everyone. However, if you would like to study the slides themselves in your own time (to avoid scrolling through the YouTube videos for a specific equation), you can buy a copy of the PDF lecture slides. This helps support the growth of the channel and allows us to provide more fluid mechanics lectures for everyone in future.
