Depends on what you intend to get out of this studying. If you want to gain some general knowledge on the subject and get a basic understanding of concepts, go on youtube and search hydrostatics, hydrodynamics (two branches of fluid mechanics) and you will find plenty of helpful videos.
If you wish to gain substantial knowledge, and understand the theory and have a usable grasp of the concepts, I have some good resources if you, or anyone, would like to read.
PS- you need to have a good mathematics background.
