Objectives

This course unit aims to make students understand and analyse the behaviour of fluids at rest and in motion, based on the fundamental laws of mechanics and using specific methodologies. Hence they can solve problems of fluid mechanics in the areas of engineering. At the end of the first month, students should be capable of: 1. characterizing fluids regarding their properties. Students should also be capable of solving simple problems using Newton’s law of viscosity. 2. applying hydrostatic principles to determine pressure, centres of pressure and manometry. 3. applying Bernoulli equation to the study of flows, discharge measurement and flow velocity. At the end of the semester, students should be capable of: 4. applying and be acquainted with the basic principles of dimensional analysis in the experimental study of fluid mechanics 5. applying mass and energy conservation equations to the study of duct flows. 6. understanding the functioning of pumps and ventilators, so that the right equipment is selected. 7. determining interaction forces associated to flows and immersed bodies

Learning outcomes and competences

Students will be able to characterize fluids in terms of their properties and actions

Eligibility for exams

To be admitted to exams, students have to be enrolled in the course unit and do not miss more classes than allowed by the rules. Besides they have to reach a minimum average mark of 8 out of 20 in both assessment components.

Calculation formula of final grade

Two tests, each with a weight of 50%.

 

Resit exam can be made to the first test (50%), to the second test (50%) or to whole subject (100%)

Examinations or Special Assignments

According to the rules: I) Students who attended to the course in previous years and who are attending this year: they will be assessed as ordinary students. However, if they wish they do not need to attend to classes. II) Students who did not attend to the course in previous years: they will be assed as ordinary students.

Special assessment (TE, DA, ...)

Regulations

Classification improvement

Recurso (resit exam) or mark improvement: Students who attended to this course unit can attend to the recurso (resit exam) and improve their marks. This exam is worth 100% of the final mark.

Observations

Lecture theatres will be equipped with multimedia equipment.
