	Objectives
	THE COURSE AIMS TO PROVIDE KNOWLEDGE ON GENERAL SCIENTIFIC CONTENTS AND METHODOLOGICAL-OPERATIONAL ASPECTS OF FLUID MECHANICS. IN PARTICULAR, THE COURSE AIMS TO PROVIDE KNOWLEDGE OF THE FUNDAMENTAL EQUATIONS GOVERNING THE MOTION OF A FLUID AND THE ACQUISITION OF THE ABILITY TO PROPERLY SIZE THOSE FLUID SYSTEMS THAT ARE GOVERNED BY A SIMPLE ONE-DIMENSIONAL BALANCE. THE MAIN KNOWLEDGE ACQUIRED DURING THE COURSE WILL BE: • DESCRIPTION OF THE MATTER AS A CONTINUUM • FLUID STATICS • BALANCE EQUATIONS ON A FINITE VOLUME, • BALANCE EQUATIONS ON AN INFINITESIMAL VOLUME • BERNOULLI'S LAW • CURRENTS WITH NEGLIGIBLE ACCELERATION • POTENTIAL FLOW • BOUNDARY LAYER FLOW • TURBULENT FLOW IN DUCTS. THE MAIN SKILLS ACQUIRED BY STUDENTS DURING THE COURSE WILL BE: • PROPERLY SIZE THOSE FLUID SYSTEMS WHOSE CHARACTERISTICS DERIVE FROM A SIMPLE ONE-DIMENSIONAL BALANCE • DETERMINE FORCES AND TORQUES ACTING ON SYSTEMS IN CONTACT WITH A FLUID AT REST OR IN MOTION. • DERIVE THE BASIC DIMENSIONLESS PARAMETERS THAT DETERMINE THE BEHAVIOUR AND THE PERFORMANCES OF A FLUID SYSTEM. • OBTAIN AN OVERVIEW OF THE DIFFERENT BEHAVIOURS THAT A FLUID CAN MANIFEST, DESCRIBING IN A SIMPLIFIED MANNER (BOTH QUALITATIVELY AND QUANTITATIVELY) THEIR MAIN FEATURES. • ACQUIRE AND USE A SCIENTIFIC TERMINOLOGY APPROPRIATE TO DESCRIBE AND MODEL A FLUID SYSTEM.

	Teaching Methods
	THE COURSE CONSISTS OF A TOTAL OF 60 TEACHING HOURS (6CFU) DIVIDED AS FOLLOWS: 36 HOURS OF LECTURES AND 24 HOURS OF PRACTICE. DURING THE PRACTICING CLASSES, PROBLEMS RELATED TO THE TOPICS OF THE COURSE WILL BE DISCUSSED AND SOLVED. ARGUMENTS WILL BE ADDRESSED WITH THE HELP OF MOVIE PROJECTIONS AND WITH THE ACTIVE PARTICIPATION OF STUDENTS.

	Verification of learning
	THE ACHIEVEMENT OF THE TEACHING OBJECTIVES IS CERTIFIED THROUGH AN ORAL EXAMINATION PRECEDED BY TWO MIDTERMS WRITTEN ASSESSMENT TESTS. THE FINAL GRADE (OUT OF THIRTY) WILL BE GIVEN BY TAKING INTO ACCOUNT THE KNOWLEDGE REACHED BY THE STUDENT ON THEORETICAL ASPECTS, HIS ABILITY TO APPLY SUCH KNOWLEDGE TO SOLVE PRACTICAL PROBLEMS, HIS COMMUNICATION SKILLS AND THE APPROPRIATE USE OF THE SCIENTIFIC TERMINOLOGY.
