Learning outcomes of the course unit
The course aims to provide an overview of the main hydraulic plant and equipment not discussed in other courses (Hydraulic Constructions, Territorial Hydraulic Protection, Hydraulic Infrastructure). Special consideration is given to supply schemes under pressure, hydroelectric plants, and the main types of open channel systems, for irrigation and reclamation purposes.
Hydraulics, Hydrology, Geotechnics, Construction Science.
Course contents summary
Water adductions: basic gravity and lifting schemes, control of transients, accumulation areas and surge tanks, piezometric wells.
Hydroelectric plants: basic schemes, plants with and without outflow regulation, pressure pipes in high head plants, current structures and special pieces in pipes, regulators, shut-off and safety parts, sizing calculations.
Hydraulic turbines: general characteristics, types and functional characteristics, fundamental equation of hydraulic turbines, similarity and characteristic number of revolutions, characteristic operating curves, operating problems of the machines.
Hydroelectric power plants: utilization programmes, automatic control of hydroelectric units, pressure control and runaway speed of the units.
Irrigation systems: purpose and types, relationships between crops, soil and climate, irrigation equipment, irrigation networks, watering methods and patterns. Drainage networks: review of hydrology, purpose, hydraulic sizing.
There are 4 numerical exercises, of which 2 are compulsory to be chosen from: 1) mass oscillation calculation, 2) water hammer calculation, 3) irrigation network calculation, 4) drainage network calculation. The exercises require the general use of a PC and some specific tools provided in the course.
