CE74.12 : Hydrodynamics 3(3-0)

Course objectives:

The main objective of this course is to provide understanding and knowledge on the fundamental principles of fluid mechanics and their simplifications for various application areas of pipeline system, open channel, hydraulic structure and hydraulic machinery.

Learning Outcomes:

The students on completion of this course would be able to:

Develop an intuitive understanding of fluid mechanics and fluid flow systems;
Identify the practical engineering problems related to water conveyance in pipes, canals and river channels;
Perform a basic analysis of fluid statics and fluid flow dynamics by means of experimental and empirical methods;
Undertake appropriate modelling tools for the design of pipeline systems and hydraulic structures; and
Apply fundamental principles of fluid mechanics to solve practical civil engineering problems on water conveyance in pipes, open channels, pumps and turbines, as well as the fluid flow over the hydraulic structure.

Time Distribution and Study Load:

Classroom lectures 40h

Tutorials 10h

Group projects and presentations 5h

Self-study (incl. assignments) 135h

Teaching and Learning Methods:

Teaching and learning methods include classroom lectures and discussions, tutorials, homework assignments and experiments. Students are given the opportunity to demonstrate their understanding of the key concepts of the course during tutorial sessions. During the course, students are requested to work in groups to conduct practical experiment tests. These group projects will help students develop the knowledge and problem-solving skills relating to the subject matter.

Evaluation Scheme:

The final grade is computed according to the following weight distributions: Coursework assignments (10%), Group project (10%), Mid-semester exam (30%) and Final exam (50%). Open-book examination is given in both mid-semester and final exams.

An “A” will be awarded if a student is able to show the ability of having elaborative knowledge on hydrodynamics and related contents, and is adequately able to apply the knowledge gained to the calculations and analyses of the fluid flow dynamics as well as the design aspects relating to the pipeline systems and channel networks. A student is in this category will typically participate in and actively contribute to the class discussions. Furthermore, the student has to fulfil all the requirements given in the individual and group assignments. A “B” will be awarded if a student shows an overall understanding of all the given topics. However, application of knowledge into practice is found wanting. A “C” will be given if a student is able to show satisfactory command over the subject matter. A “D” will be given if a student displays very limited knowledge of the subject matter, and does not appear motivated to learn new things.
