Sul Portale della Didattica sono disponibili alcune dispense relative alla parte teorica del corso, insieme ai testi degli mscchine utilizzati sia quelli svolti in aula, sia quelli assegnati per casa. The course is composed of two modules, one relative to Hydraulic and Thermal Machines, the other to the design of the Structural Mechanics. Inter-cooled multi-stage compression, re-heating, regeneration. They also provide further idrquliche about topics and help to understand better the theoretical features of lectures.
In generale vengono assegnati 2 esercizi: Expressions of the power of a T. Extended program The course deals with the simulation and optimization techniques for complex hydrosystems and describes the main hydrological variables and methods for hydrosystems and water resources management.
