Learning outcomes

Provide the fundamental notions of Mechanics of Continuous Fluids and Hydraulics necessary to profitably follow the following application courses. At the end of the course the student is able to carry out checks and projects of simple pressure and free surface schemes.

Course contents

Prerequisites/recommended preparatory courses The student who accesses this teaching knows and knows how to use the basic principles of mathematics and physics. All lessons will be held in Italian. An understanding of the Italian language is therefore necessary in order to profitably follow the course and to be able to use the teaching material provided. Plan Generality Description of currents and mechanical characteristics of fluids. General principles. Quantities and units of measurement. Dimensional analysis. Buckingham's theorem (pi). Patterns of continuous medium. Density, viscosity, compressibility. Equation of state. Equation of continuity. Hydrostatics Global and point equations of statics. Action of liquids on surfaces at rest. Pressure measurements in fluids at rest. Thrust on flat and curved surfaces. Equilibrium of immersed or floating bodies. Fluid dynamics Stress tensor and strain rate tensor. constitutive equations. Newtonian and non Newtonian fluids. Velocity and acceleration of fluids in motion. Momentum theorem. Euler equations. Bernoulli's theorems. Navier and Stokes equations. Hydrodynamic actions against solid surfaces. Phoronomy. In conduct Reynolds experiment: laminar and turbulent flow. Uniform flow in pipelines. Effective load losses due to sudden variations in section. Pipe networks. Pumping plants. In channel Uniform motion and permanent motion in free surface ducts. Energy transformations in free flowing courses: slow and fast currents. Hydraulic jump. Passages above the threshold and under the sluice gate. Venturi Canal. Measurement weirs.

Teaching methods

The course takes place through frontal lessons, classroom exercises and computer-programmed exercises. The lessons illustrate the principles and the fundamental theoretical and practical notions. In the classroom exercises, applications of the notions are illustrated with numerical examples.

Assessment methods

The verification of learning takes place through a written test and an oral test. The written test, lasting 3 hours without the help of notes or books, normally consists of 3 exercises on the most significant topics of the course, addressed in classroom exercises. To be admitted to the oral exam it is necessary to obtain a minimum score of 18/30 in the written exam. The oral test consists of a discussion with the teacher, aimed at ascertaining the knowledge acquired, as well as the ability to synthesise and apply key knowledge. Passing the exam will be guaranteed to students who demonstrate good knowledge and understanding of the key concepts illustrated in the teaching, together with good application skills. A higher score will be awarded to students who demonstrate mastery and ability to use all the teaching contents, illustrating them with logical order, technical language properties and critical ability. Failure to pass the exam will be due to insufficient knowledge and/or understanding of the key concepts, lack of command of the technical language, lack of or insufficient application skills.
