Base Knowledge
Knowledge of mathematics and physics obtained in the curricular units of the previous semesters
Teaching Methodologies
Teaching consists of an initial theoretical presentation, followed by practical exercises. The exercises portray
real situations, making the pupils familiar with the way fluid mechanics can be applied to the resolution of
engineering problems. In the theoretical presentation the expository and inquisitive method is used. In the
practical applications a demonstration of the methodologies is first introduced. Then new problems are
proposed and students are encouraged to find out the solution. In the laboratorial lessons several assays are
carried through, having the pupils to elaborate a small report. This activity has didactic value and allows the
pupil to relate the theory with the obtained practical results.
A final exam with a theoretical part (7 points) and a practical part (11 points) is carried through; the set of
practical laboratory works has a quotation of 2 points. The approval requires a global positive mark with a
minimum of 2 points in the theoretical part.
Learning Results
The main objective of this course is to provide the basic training in hydraulics (to be complemented
in the course unit of Hidráulica Geral 2) required for the activity of an engineer in planning, design and
management of hydraulic systems. On successful completion of this module, students will have:
The ability to solve problems in the domain of hydrostatics;
The ability to analyze design and sizing simple installations with pressure flow, with or without turbomachinery;
The ability to evaluate the stresses generated by flow in its solid boundaries and their supporting structures or
mooring;
The ability to understand reduced model testing.
