An initial approach to Fluid Mechanics is presented from the point of view of a Mechanical Engineer. The examples of application that are presented illustrate problems that are encountered by Mechanical Engineers in their daily work. The structure of the course is also tailored to review previous concepts and provide solid foundation for subsequent courses.
