Montuori: "Le equazioni globali della meccanica dei fluidi e l'interpretazione energetica del carico idraulico". Its main aim is to provide students with the basic analytical tools to analyze quantitatively flow processes. In such a context, both the local by means of differential equations and global approach will be followed. Particularly, the continuity equation and the momentum equations will be derived from the fundamental eqautions of Physics, as relaible tools for engineers.
Moreover, attention will be paid to empirical relationships that are used for solving practical problems of the hydraulic engineering. For each empirical relationship, the range of validity will be pointed out. The main competence will be: - to use the proper approach local, global, 1-D modeling ; - to analyze the given problem selecting data and unknowns properly; - to solve implicit equations e.
Prerequisites In order to be able to understand and apply most of the topics explained during the course, you must have successfully passed the Analisi Matematica 1 exam as well as know topics of the Geometria Analitica and Fisica I exams; moreover you should attend the Meccanica Razionale and Analisi II courses.
Particularly you should be familiar with continuous functions, limits, derivatives, and simple and double integrals. For all topics, the strong links between theory and practical engineering problems are pointed out. Specifically, steady- and unsteady state tests will be carrie out in pressurized pipes to analyze energy dissipation and pressure wave mechanisms.
Moreover open channel flow tests will be considered in the laboratory channel. Learning verification modality With regard to the modality of the exam, you have the following two options: two-steps exam: within such a modality, the exams consists in two phases. The first phase happens immediately before the beginning of the second semester: it is a written exam concerning the topics explained during the first semester but with no exercise usually three questions; available time: 1.
The second phase consists in an oral test, with a duration of about 30 minutes, which includes two questions about the topics explained during the second semester and an exercise about one of the practical topics discussed during the whole course.
Within both the modalities, your communication skill and autonomy in the organization and exposure of the topics will be tested. A problem concerning hydrostatics, steady-state flow in pressurised pipes, and steady-state flow in open channels has to be solved numerically to be admitted to the oral exam.
