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. The fundamentals of cinematics and dynamics in the fluid mechanics context;
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 and energy requirements, available flow and dimensioning simple ducts;
6. Characteristic curves of pumps and fans in orthet to select and analyse the behaviour of this equipment;
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, 25 minutes in duration.
Written examination at the time of examinations. Limited consultation, 120 minutes in duration. A minimum grade of 7/20 is required as the average of the theoretical tests to have access to this practical test.
The grade will be obtained weighting by 25% the average grade in the theoretical tests and by 75% the practical test.

The improvement/final examination includes, as a whole, both theoretical and practical components.The same weights (25% - 75%) and minimum grade in theoretical component (7/20) will be used in the improvement/final examination.

Examinations or Special Assignments

Not planned.

Internship work/project

Not applicable.

Special assessment (TE, DA, ...)

FEUP rules to be considered.

Classification improvement

According to FEUP regulations, with rules similar to the ones of improvement/final examination.
