Objectives

Objectives: Teaching the concepts, principles and fundamental theories that describe the behaviour of several types of flow phenomena. Teaching the theories and methods used in Civil Engineering for the planning and design of flow control works and hydraulic structures. 

Learning outcomes and competences

Skills and learning outcomes: Knowledge of basic science and core knowledge of Engineering (Engineering Sciences); engineering reasoning and problem solving attitudes; acquisition of inter-personal skills, individual and team work capacity; oral and written communication.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Recommended: Algebra, Calculus, Mechanics.

Program

1. Hydrostatic: fundamental principle; hydrostatic thrust on surfaces.
2. Fundamental Theorem of Fluid Mechanics (integral formulation): continuity, Bernoulli's theorem, theorem of momentum.
3. Flow through orifices and weirs.
4. Dimensional Analysis and Similitude.
5. General Equations of Fluid Mechanics (differential formulation): conservation of mass, conservation of momentum.
6. Types of Flows: irrotational flow and flow boundary layer (laminar and turbulent).
7. Pressure Flows: establishment of flow; experiences of Nikuradse; types of flow (laminar, transitional and turbulent); continuous head loss; resistance formulas; local head loss.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:
This curricular unit presents the basic principles of hydraulics for the exercise and practice of civil engineering, introducing the themes to be developed in the curricular units of the specific area of Hydraulics, Water Resources and Environment.

Teaching methods and learning activities

Lectures for theoretical framing and exposure, introduction to problem solving and engineering approach for real life problems. Classroom classes (tutorial type) for problem solving practice, including computational work. Laboratory class for hydraulic phenomena visualization, demonstration, and measurement.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
The presentation of the concepts, principles and fundamental theories by using interpretation of illustrative examples aims to develop scientific thinking on hydraulics phenomena and flows. In this way a proper attitude and thinking is developed to solve engineering problems and a solid basis for the subsequent curricular units is acquired, allowing the use of correct techniques and rigorous problems formulation.

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.

Calculation formula of final grade

EF: Final Exam. Written exam to be conducted in Normal and/or Appeal Periods of Exams, with a theoretical part, without consultation, and a practical part, with consultations (charts provided with the exam sheet). Maximum duration: 3 h. Rating: 0‒20 values (rounded to one decimal place). 

 

CAD: Distributed Component Evaluation (optional). Written exam to be held during a lecture, with a Maximum duration: 45 min. Rating: 0‒20 values (rounded to one decimal place).  

 

Due the optional nature of the CAD assessment, imposed by the Regras de Avaliação do MIEC (Rules of Assessment of MIEC), the FINAL GRADE (CF) is the largest value obtained by calculation of the following expressions: 

 

CF1 = 0.75 EF + 0.25 CAD (rounded to one decimal place) 

CF2 = EF (rounded to one decimal place) 

 

i.e. 

 

CF = max {CF1, CF2} (rounded to the nearest unit) 

 

Note 1: ALL students enrolled in the Course are graded according to this rule. This includes any Special Statute student. 

 

Note 2: To calculate the final grade (CF) only the marks obtained on exams (either EF or CAD) sat in the CURRENT academic term shall be considered. 

Examinations or Special Assignments

Laboratory Work to be carried out during a practical class (optional).

Special assessment (TE, DA, ...)

Special Statute students who sit for a Special Season exam will be evaluated in one only exam with the same characteristics of the Final Exam (EF).

Classification improvement

Students who sit for an exam for Improvement of Final Grade will be evaluated in one only exam with the same characteristics of the Final Exam (EF).

Observations

Estimated working time outside the classroom: 3 hours Mobility students may carry out the Final Exam and/or the components of the Distributed Evaluation in Portuguese or English. Mobility students in mobility may have tutoring in English during the practical classes, if they so request.
