The course provides the fundamentals of the motion of fluid currents and the tools for the design and verification of simple hydraulic systems and to address more complex problems in a global form
The course provides the fundamentals of the motion of fluid currents and the tools for the design and verification of simple hydraulic systems. In detail, it deals with the following topics: forces acting in a fluid at rest, the thrusts exerted by a fluid on flat and bumpy surfaces, the tension in a moving fluid and the principles that regulate the movement of a fluid current. On the basis of the topics discussed, exercises on the thrusts exerted by fluids and problems relating to simple systems are proposed.
Among the transversal skills we intend to develop functional alphabetic competence (basic level - ability to communicate effectively in written and oral form, adaptation of one's communication to the context, use of sources and aids of various kinds); personal competence (basic level - ability to identify one's own abilities, ability to concentrate and critically reflect on a task); the ability to learn to learn (basic level - awareness of one's preferred learning strategies, organization and evaluation of personal learning according to what is understood and learned).
Lessons and exercises; tests using Wooclap and Mirò at different moments of the course; simulation in class with the development of exercises by the students, exposure and discussion of any critical issues related to the resolution.
Working students and students with DSA certification, disabilities or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and exam methods which, in compliance with the teaching objectives, take into account individual learning methods.

The exam includes a written and an oral test. During the course there are tests which allow, if passed, direct access to the oral test.
Pre-requisites : notions of maths, geometry and physics
