HYDRAULICS

The course is part of the core educational activities of the Environmental Engineering for Ecological Transition program. It aims to provide the fundamental elements of fluid mechanics and hydraulics with the purpose of: framing fluid mechanics issues starting from the identification of hypotheses, deriving descriptive analytical expressions, and using such expressions to obtain quantitative solutions.

-Knowledge of the basic principles of fluid mechanics and hydraulics governing the operation of hydraulic infrastructures (drainage networks, aqueducts, treatment plants) and the natural water cycle.
Skills:
- Calculate pressure forces.
- Solve the motion in single pipes under pressure given the boundary conditions;
- Calculate the motion in pressurized hydraulic networks;
- Calculate the motion in pipes or channels with free surface;
