Hydraulics I
Objectives
To give students knowledge in the areas of dimensional analysis, hydrostatics, pressure flows, characteristics and selection of pumps and turbines, flows through orifices and weirs and free-surface flows. At the end of the curricular unit students should have the following abilities:
• Expertise in the computation of hydrostatic forces acting on different surfaces.
• Expertise in the fundamental concepts of hydro-kinematics and hydrodynamics (pressures, mean velocities, forces, stresses and energy balances).
• Expertise in the hydraulic computation of steady flows in conduits under pressure.

Teaching method
Lectures: oral presentation, whenever suitable supported with photographs and examples of real situations representing practical implementation of discussed topics.
Lab sessions: resolution of problems on applied hydraulics; practices in the Hydraulics Laboratory, with presentation and manipulation of scale physical models, illustrative of fundamental hydraulic laws.
Evaluation method
Final grade = 0.425 x T1 + 0.425 x T2 + 0.05 x L1 + 0.05 x L2 + 0.05 x L3, where 0.425 x T1 where T1 and T2 are the classifications of tests 1 and 2 and L1, L2 e L3 are the classifications of the laboratory work reports 1, 2 and 3.
The two tests may be replaced by the exam and, in that case, it will be Final grade = 0.85 x E + 0.05 x L1 + 0.05 x L2 + 0.05 x L3, where E corresponds to the Exam classification.
