Hydraulics

Course description

The course aims to provide the theoretical and practical fundamentals for the comprehension of the flow of fluids in pressure and free surface, and in particular:
-a broad and comprehensive vision of stresses in continuous systems;
- a clear understanding
ot the pressure and free surface currents;
- techniques and methods used to solve the main statics and design and verification of pipelines;
- a solid basis for possible continuation of academic studies.

Knowledge and understanding: The student must demonstrate knowledge related to the concepts and the problems of the pressure and free flow hydraulics.
Ability to apply knowledge and understanding: The student must demonstrate how to use the acquired concepts and tools to solve the basic problems of thrusts on plane and curved surfaces and design and verification pressure flow problems.
Judgment autonomy: The student must be able to know how to independently evaluate the processes of statics and pressure hydraulics and to indicate the main calculation methods.
Communicative Skills:
The student must have the ability to easily explain the concepts of the statics and pressure hydraulics with the correct use of scientific language.
Learning Skills:
Students must be able to progressively acquire autonomy and to continuously update their knowledge through the study of publications (also in English) in order to acquire the ability to deepen the topics of Hydraulics.

Prerequisites

Analisi Matematica 1, Fisica 1

Syllabus

Fundamentals of Fluid Mechanics - Definition of fluid and its properties. The continuous fluid. Forces acting on a continuous fluid. The state of tension in a still fluid. The state of tension in a moving fluid. Derivative material and local derivative, transport theorem. The principle of conservation of mass and momentum in a global form. State of tension in a still fluid, cardinal equations of the static, static thrusts on flat surfaces and humps. Tension state in a moving fluid, the tension tensor. Ideal fluid scheme and Bernoulli theorem.
Fluids in stillness: the static equation - The distribution of pressure in an incompressible fluid and in a barotropic fluid. Evaluation of the forces exerted on flat surfaces and humps.
Fluids in motion: the current scheme - Fluid currents: definition and characteristic quantities. The principle of conservation of mass and momentum for a current.
The currents under pressure - The calculation of the resistances distributed in the pressure currents in steady and uniform motion. Concentrated energy dissipation in pressure currents. Design and verification of simple pump systems.
Free surface currents - the calculation of the resistances distributed in steady and uniform motion currents, the uniform depth of motion. Possible states of free surface currents, critical depth. Stationary and non-uniform currents, the equation of profiles.

The course aims to provide the fundamentals and main tools of Hydraulics.
