Objetivos
Students will discover the basic principles of Fluid Mechanics, and will comprehend its different applications in Hydraulics, most specifically in what civil engineering is concerned. With this discipline, students will be able to solve current hydraulic problems, namely in hydrostatics and circuits under pressure, to identify more complex problems that will require a specialized support, and to enroll a technical description of the problem with such a specialist. This discipline is complemented with Hydraulics II.
Students should develop their competences in work planning and team work. It is fundamental that they work on their reporting skills, mainly in writing, and that they improve their responsibility and commitment as far as deadlines are concerned. This curricular unit is a basic science for a civil engineer, so students must assure
Resultados de aprendizagem e competências
The syllabus assures that all the curricular unit’s objectives are met, starting with basic concepts, such as flow properties and hydro-statics, and ending with more complex power pipe networks. In each topic, theoretical concepts are taught in a way that students understand the simplifying hypotheses that are assumed in each context, learn when and why those can be made, in order to provide them with the ability to, in the future, understand whether they have the knowledge to undertake – or not – more complex studies. Practical courses are always prepared with examples that have a strong connection to civil engineering situations.

Métodos de ensino e atividades de aprendizagem
The teaching methodology assures that students are evolved with problem solving and searching for a growing autonomy in such a task, which presents growing difficulty. This continuous work is enhanced by the possibility of submitting 4 tests. Practical work is complemented with assiduous visits to the Hydraulics Laboratory, either with the teacher or not, to implement the experiences needed for the reports. Work organization and team work are promoted through the laboratory group reports. Student’s responsibility towards deadlines is promoted with penalization of late deliveries. Students have a feedback on the quality of the reports through their grade and by a teacher report on their major drawbacks and chances for improvement. Personal learning outcomes are evaluated based on individual written evaluation and on oral discussion for grades above 16 values.
