1) Basic knowledge of components and systems, as far as their design features and operating principle are concerned. .2) Acquaintance with the main physical quantities, measurement units, conversion factors, order of magnitude of numerical values in the field of fluid-machines. .3) Ability to apply theory for facing some typical problems, also by answering specific questions with the help of suitable calculations. .4) Acquisition of a reference method ("model-procedure" or "standard-procedure") for developing reasoning about fluid-machines. .5) Minimum culture necessary for understanding information sheared among the operators (manufacturers,providers,customers,sellers,etc.).

Some preliminary knowledge coming from courses dealing with topics of: mathematics, physics, applied mechanics, thermodynamics, heat-transfer, hydraulics and fluid-mechanics.

Each group of lectures dealing with a specific topic is immediately followed by a session of exercises: some are solved together, some are supplied for homework. The exercises give chance to practice the theoretical principles, the measurement units, the order of magnitude of numerical values. They also provide further information about topics and help to understand better the theoretical features of lectures.

Notes on theoretical and practical topics are available on the on the polito web-site, along with schematics, tables, graphs employed during the course.

Exam: Written test; Optional oral exam;

L’esame consiste in una prova scritta, che richiede competenze sia di teoria che di calcolo. La durata dell’esame è di 2 ore. In generale vengono assegnati 2 esercizi: uno sulla parte "componenti", uno sulla parte "impianti". Lo studente decide quale esercizio affrontare per primo e quanto tempo dedicare a ciascuno. E' possibile consultare libri e appunti durante la prova. Lo studente è valutato in base alle capacità mostrate di: .1) padroneggiare le sue conoscenze, integrando teoria e pratica, .2) motivare le scelte fatte (formule, ipotesi, assunzioni, semplificazioni …), .3) commentare e valutare criticamente (se necessario) i risultati ottenuti, .4) esporre il procedimento seguito, in modo chiaro, sintetico e coerente. Per passare l’esame bisogna raggiungere o superare la sufficienza (18/30) in ciascuno dei due esercizi.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
