Knowledge of the methods, principles and laws taught in the scope of the discipline, to allow a theoretical and practical approach of problems and questions of the forum of applied hydraulics of pressure flow and of free-surface flow, including kinematics laws and orifices and spillways.
Lab sessions attendance (minimum 2/3) and accomplishment of six lab experiments with correspondent lab reports.
Fluids physical properties: physical constants; dimensional analysis. Hydraulic Basics: kinematics; dynamics; flow energy; momentum; flow establishment. Hydrostatics: fundamental equations; pressure distribution; hydrostatic thrust. Closed conduit flow: i) head loss in conduits: general equation; Reynolds number; absolute roughness and relative roughness; smooth pipes and rough pipes; resistance coefficient; Moody diagram; explicit equations; conduit ageing; ii) head loss produced by transitions and fittings and other singularities; equivalent length of conduit. iii) energy grade line and hydraulic grade line design; position of the hydraulic grade line in relation to conduit. Open channel Flow: types of flow; velocity and pressure distribution; Froude number; normal depth; specific energy; depth-discharge curve; critical flow; water surface profiles; hydraulic jump; orifices and Bazin type spillways.
