|---|---|
| THE COURSE AIMS TO THE ACQUISITION OF THE FUNDAMENTAL PRINCIPLES OF THE HYDRAULICS AND MORE GENERALLY OF THE FLUID MECHANICS, WITH SPECIAL CONCERN TO ENVIRONMENTAL ENGINEERING PROBLEMS. BESIDES THE RIGOROUS TREATMENT OF THE THEORETICAL ASPECTS OF THE HYDRAULICS AND THE FLUID MECHANICS, THE COURSE COMPREHENDS CLASSROOM EXERCISES AND EXPERIMENTAL ACTIVITIES TO BE PERFORMED AT THE LOCAL ENVIRONMENTAL AND MARITIME HYDRAULICS LABORATORY (LIDAM). EXPECTED LEARNING RESULTS KNOWLEDGE AND LEARNING ABILITIES -KNOWLEDGE OF PROBLEMS RELATED TO THE BEHAVIOUR OF FLUIDS, EITHER AT REST OR IN MOTION. ASSESSMENT OF THE HYDROSTATIC OR THE HYDRODYNAMIC FORCE ON PLANAR OR CURVED SURFACES, EVALUATION OF THE FORCE, ASSESSMENT OF PROBLEMS RELATED TO THE MOVING OF FLUIDS IN PIPES OR OPENED TO THE ATMOSPHERE. -ABILITY OF ASSESSING THE INFLUENCE OF OPERATIONAL PARAMETERS, E.G. WATER LEVELS, FLOW RATES, TOTAL HEADS IN HYDROSTATIC AND HYDRODYNAMIC PROBLEMS. ABILITY OF APPLYING KNOWLEDGE AND UNDERSTANDING -ABILITY OF APPLYING THE FUNDAMENTAL PRINCIPLES OF THE HYDRAULICS AND MORE GENERALLY OF THE FLUID MECHANICS FOR THE DESIGN AND VERIFICATION OF PROBLEMS INVOLVING FLUIDS EITHER AT REST OR IN MOTION. -ABILITY OF PREDICTING THE RESPONSE OF HYDROSTATIC OR HYDRODYNAMIC PROBLEMS AS FUNCTION OF IMPOSED INITIAL AND BOUNDARY CONDITIONS. PERSONAL JUDGEMENT THE STUDENT WILL BE ABLE TO JUDGE ON HIS OWN: -TO WHAT EXTEND IS POSSIBLE TO APPLY A SOLVING SCHEME TO TACKLE WITH PROBLEMS FEATURING FLUIDS EITHER AT REST OR IN MOTION. -THE RANGE OF APPLICATION OF THE FUNDAMENTAL PRINCIPLES OF THE HYDRAULICS AND MORE GENERALLY OF THE FLUID MECHANICS COMMUNICATION SKILLS THE STUDENT WILL BE ABLE TO DEBATE ABOUT THE FUNDAMENTAL PRINCIPLES RULING HYDRAULIC AND FLUID MECHANIC PROCESSES, DISCUSSING FIELDS OF APPLICATION AND RELATED LIMITS, USING A PROPER SCIENTIFIC TERMINOLOGY. |

| Teaching Methods | |
|---|---|
| THE COURSE OF TOTAL 12 CFU / 120 HOURS IS PROVIDED THROUGH TWO CONSECUTIVE MODULES OF 6 CFU / 60 HOURS. EACH MODULE INCLUDES FRONT LESSONS (4.5 OF 6 CFU / MODULE) AND EXERCISES IN THE CLASSROOM AND AT THE LOCAL ENVIRONMENTAL AND MARITIME HYDRAULICS LABORATORY (LIDAM) (1.5 OF 6 CFU / MODULE). LABORATORY EXERCISES AIM TO STIMULATE THE ABILITY OF CRITICAL JUDGMENT SKILLS AND ACTIVELY INVOLVE STUDENTS IN THE HYDRAULIC AND FLUID-DYNAMIC PROCESSES. OVERALL, THE COURSE CONSISTS OF FRONTAL LESSONS (90 HH), CLASSROOM EXERCISES (22 HH) AND EXPERIMENTAL MEASUREMENTS (8 HH) AT THE LOCAL ENVIRONMENTAL AND MARITIME HYDRAULICS LABORATORY (LIDAM). CLASS ATTENDANCE IS MANDATORY WITH MINIMUM ATTENDANCE RATE OF 70% |
| Verification of learning | |
|---|---|
| THE ACHIEVEMENT OF THE LEARNING OBJECTIVES IS ATTESTED AT THE END OF THE COURSE THROUGH THE PASSING OF A WRITTEN EXAM (DURATION 2 HH) WHICH IS PREPARATORY TO THE SUCCESSIVE ORAL EXAM (DURATION 1 HH). TO SUCCESSFULLY UNDERGOING THE ORAL EXAM, A MINIMUM SCORE OF 18/30 MUST BE ATTAINED AT THE WRITTEN EXAM. THE ORAL EXAM WILL CONSIST OF A CONVERSATION IN WHICH POSSIBLE GAPS SHOWN DURING THE WRITTEN EXAM WILL BE SOLVED. THE MAXIMUM SCORE CUM LAUDE WILL BE CONFERRED ON THE BASIS OF: -THE QUALITY OF THE EXPOSITION WITH THE USE OF A PROPER SCIENTIFIC TERMINOLOGY -THE ABILITY OF CORRELATING DIFFERENT TOPICS LEARNT DURING THE COURSE, AND POSSIBLY WITH REFERENCE TO OTHER DISCIPLINES -THE PERSONAL JUDGEMENT SHOWN DURING THE EXPOSITION. THE MINIMUM SCORE (18/30) AT THE ORAL EXAM WILL BE CONFERRED WHEN THE STUDENT SHOWS AT LEAST A BASIC KNOWLEDGE OF THE FUNDAMENTAL PRINCIPLES RULING HYDRAULIC AND FLUID MECHANIC PROCESSES AS WELL AS NO SEVERE HESITATION ON THE APPLICATION OF SOLVING METHODS OF HYDRAULIC SHEMES IS EXHIBITED. |
