Skills


Basic skills
  • B1_Students have demonstrated knowledge and understanding in a field of study, based on general secondary education, and are accustomed to finding a level that, while supported by advanced textbooks, includes also some aspects that involve knowledge coming from the vanguard of his field of study

     

     

Specific skills
  • Know the basics of fluid-mechanical machine systems

Description


The subject is one of the two subjects of the subject of Thermal Engineering and Fluids of third course. This area aims to present advanced applied knowledge and advanced design methods to solve various real problems of these two subjects. The subject of Fluid Engineering uses in an important way the most theoretical and basic knowledge of the subject of Thermodynamics and Fluid Mechanics, but also presents more advanced knowledge, applicable to real situations when the energy of a fluid or the movement of a fluid play an important role. In addition to advanced knowledge, the subject presents design methods, sizing, selection process and methods for locating problems in real situations.

Evaluation system


The evaluative weight of the different concepts that take part in the qualification of the asignatura are:

- E1: Examination of the first part (30%)

- E2: Examination of the second part (30%)

- P2, P4, P6, P9 and P10: Internship reports (5 x 6% = 30%)

- P3, P5, P7 and P8: Practice tests (4 x 2,5% = 10%)

Practice note (PR) = 0,75 x (P2 + P4 + P6 + P9 + P10) / 5 + 0,25 x (P3 + P5 + P7 + P8) / 4

Each student must obtain a minimum of 40% of the maximum mark of the exam and a minimum of 40% of all reports and practice tests, as well.

  • If E1 <4 and / or E2 <4: Final note = Minimum (E1, E2, PR)
  • If PR <4: Final note = 0,3 x E1 + 0,3 x E2
  • If E1> 4, E2> 4 and PR> 4: Final note = 0,3 x E1 + 0,3 x E2 + 0,4 x PR

Recovery

Internships are not recoverable.

At the end of the semester, a resit exam is offered as long as the School Studies Department indicates so. The recovery will take place on the date and place set by the School Studies Department. During the resit exam the maximum grade that can be obtained is a 5 and it is calculated with the following formula where ER is the grade of the resit exam. The maximum grade will in any case be a 5:

  • If ER <4 or PR <4: Final note = Minimum (ER, [0,6 x ER + 0,4 x PR])
  • If ER> 4 and PR> 4: Final note = Maximum (ER, [0,6 x ER + 0,4 x PR])
