Class Hydraulics II

The scope of the discipline covers: a) the application of the fundamental hydrostatics equation for immersed bodies in fluids at rest; (b) the application of the general hydrodinamic equation for flows.  The students should acquire the following skills: i) design of hydraulic systems and structures; ii) calculation of pressure forces on immersed bodies; iii) Knowledge of the global behavior of flows and iv) concept of energy and energy losses in flows under pressures and in free surface.

The teaching-learning methods will be based on the work developed in the classes, in the study and in the research / consultation of bibliography by the student. During the theoretical sessions, the teacher will present and discuss the programmatic contents, applying the knowledge acquired to concrete situations presented. In the practical sessions, students will be involved in the discussion / resolution of exercises or proposed problems, of experimental practical work, as well as being asked to work outside the room. At certain times, the student, individually or in groups, will be required to give an oral presentation of their work. Study visits are planned.
