Teaching methods
The course is composed of lectures and exercises .
Lectures will present principles, theoretical results and practical tools.
Assessment methods
The assessment is done through an oral test during which the student is called to explain concepts, demonstrations and principles concerning the behavior of fluids; furthermore, the candidate must demonstrate to be able to correctly frame and solve problems related to the fluid motion and the design of simple hydraulic circuits.
Grades are expressed in thirtieths: the minimum grade for passing the exam is 18/30, the maximum mark is 30/30 with honors. In order to pass the exam, the student must demonstrate sufficient knowledge of all the subjects and not present significant gaps.
The calendar of oral tests and written tests is published well in advance on the AlmaEsami web platform of the University of Bologna. Students intended to take the test must first register on the list of the chosen exam, then, show a document of recognition on the day of the exam.
