Objectives

The objectives are consistent with the development of skills related to design assistance of building sector, the analysis and evaluation of architectural and building engineering products and the maintenance of building artifacts, with reference to hydraulic systems.
Expected knowledge:
the teaching involves the acquisition of knowledge of base hydraulics to support the design and management of hydraulic systems serving the built area with reference to:
- hydrostatic and hydrodynamic;
- hydraulics of pressurized systems;
- hydraulics of free surface systems.
Expected skills:
- analyze the stresses due to fluids at rest and in motion (hydrostatic and hydrodynamic);
- schematize and analyze motion processes for pressurized water systems, in particular for the definition and solution of design problems and verification of water distribution networks;
- schematize and analyze motion processes for free surface water systems, in particular for the definition and solution of common design problems and verification of open channels and drainage networks.

Contents

The course provides the basic notions of hydraulics for the design and management of water systems serving built areas and working under pressure and on free surface. The contents of the course contribute to developing the specific skills of the three-year graduate in Construction Engineering regarding the activities connected with the production cycle of buildings.

Teaching Methods

The course will be articulated in lectures and exercises by using multimedia presentations and spreadsheets.

Evaluation methods

Verification of learning:

The verification of the learning takes place through an oral exam. The student is required to illustrate the theoretical foundations of the main topics of the course and the solution of some specific problems, also with numerical examples.
In particular, during the oral exam a mark out of thirty is assigned to each answer to three questions relating to the main thematic areas of the program: (i) hydrostatics and conservation principles; (ii) hydraulics of pressurized systems; (iii) hydraulics of free surface systems.
In the event that the question requires the presentation of a specific topic of the program, the candidate's ability to clearly expose the concepts and contextualize them for the analysis of technical problems, particularly in the field of civil engineering, is evaluated.
In the event that the question requires the resolution of a numerical example, the approach to resolution is evaluated, in addition to the technical consistency of the results.
The final mark is assigned as the average of the marks obtained from the three questions.
