Excellent introductory guide into the theory of fluids with classic example flow situations. Well presented with solid explanations and sparing use of maths. HIGHLY RECOMMENDED.
"Multimedia Fluid Mechanics", ISBN: 0-521-78748-3
A CD-ROM providing an experimental introductory into fluid mechanics. Excellent presentation and lots of videos of classic experiments. Certain presentations are interactive, for example, watch what happens to the flow around an aerofoil as you click and change the angle of attack! HIGHLY RECOMMENDED.
