This is a first course in the great subject of fluid mechanics, which fascinated from Leonardo da Vinci to every one of the great physicists of modern times. As an engineer, you will most certainly deal with problems related to fluid behavior, so understanding this behavior is an essential aspect of being an engineer, regardless of your field of specialization. Topics of this course include fluid statics, Bernoulli equation and applications, fluid kinematics, finite control volume analysis and applications, conservation of mass, momentum and energy, differential analysis of fluid flow, viscous flow and the Navier-Stokes equations, dimensional analysis, pipe flow and pipe systems, flow around immersed bodies and boundary layers. Professor Lorena A Barba Mechanical Engineering Department Boston University
