Objectives

Analyse, understand and characterize, based on fundamental laws of mechanics and using specific methodologies, the behaviour of fluids at rest and in motion, in view of solving problems of fluid mechanics in engineering.

Learning outcomes and competences

It is expected that, at the end of the semester, students will be able to/know:
1. Characterize fluids in terms of their properties and to solve simple problems involving Newton's viscosity law;
2. Apply the principles of the static of fluids to manometry and to the characterization of pressure forces on flat immersed surfaces;
3. Apply the equations of conservation of mass, energy and linear momentum to ideal fluid flows;
4. Use dimensional analysis and similarity principles in fluid mechanics problems;
5. Apply the equations of conservation of mass and energy to flows in ducts, calculate pressure losses, energy requirements and available flow, and dimensioning simple ducts;
6. Characteristic curves of pumps and fans in order to correctly select these equipments;
7. Characterize the forces resulting from the interaction of flows with immersed bodies.

Eligibility for exams

Presence in, at least, 70% of the practical sessions.

Calculation formula of final grade

Two theoretical tests in Moodle, one in the middle and one at the end of the semester. Tests without consultation, 20 minutes in duration.
Written examination at the time of examinations. Limited concultation, 120 minutes in duration.
The grade will be obtained weighting by 20% the average grade in the theoretical tests and by 80% the practical test. A minimum grade of 7/20 is required as the average of the theoretical tests.
The same weights and minimum grade in theoretical component will be used in the improvement/final examination.
The improvement/final examination includes, as a whole, both theoretical and practical components.Two theoretical tests in Moodle, one in middle and one at the end of the semester. Tests without consultation, 20 minutes in duration.
Written examination in the examinations period. Limited concultation, 120 minutes in duration.
