Objectives

To know the fundamentals of Fluid Mechanics, including the characterization of fluids and its differences comparing to solids. To know the fundamental laws of fluids at rest, and its interaction with confining surfaces. To learn the principles of mass, momentum and energy conservation apllied to fluid flows, both in its integral and differential formulations. To learn and to apply the dimentional analysis and similitude principles, regarding the experimental study of Fluid Mechanics. As an ultimate objective (and along with Fluid Mechanics II) it is aimed that the students acquire the ability to resolve concrete problems of Fluid Mechanics in any engineering area and more specifically in Mechanical Engineering.

Teaching methods and learning activities

The course is organized in two independent groups, each with three theoretical-practical classes of 1.5h per week. In each class theoretical concepts are exposed and followed by the application of practical cases. 

Evaluation Type

Distributed evaluation without final exam

Eligibility for exams

The student cannot exceed the absence limit allowed (25% of the practical classes), according to the current rules.

Calculation formula of final grade

Evaluation through two tests, one at the middle of the semester (A) and the other at the end of the semester (B). The final provisional mark is 50%A + 50% B.  The resit exam covers the whole material, hence a weight of 100% and the final mark is the best of the resit exam mark and the provisional final mark. 

Special assessment (TE, DA, ...)

A single exam to the whole material taught and with a weight of 100%

Classification improvement

Classification improvement exam will take place at the same time as recurso exam.
