COURSE PURPOSE:
The aim of this course is to develop in students an understanding of the basic
principles of fluid mechanics and of the applications of these principles to civil and
engineering problems. This course adds to the knowledge base of the engineering student
and reflects the primary purpose of the Bachelor of Engineering in Civil Engineering to
provide a practical and professional engineering education.
During the course, opportunities will be given to develop a range of generic skills
including written communication, problem identification and analysis and critical
evaluation. Students will also have the opportunity to practice and enhance their ability to
work effectively as a member of a team.
As the first of the fundamental courses in water engineering, this course will form
the basis for subsequent courses such as Fluid Mechanics-II, Engineering Hydrology,
Hydraulic Engineering and Irrigation Engineering, etc and allow students to further
develop the skills necessary for the analysis and design of hydraulic structures in civil
engineering.
COURSE OUTCOMES AND OBJECTIVES:
In terms of technical content, upon successful completion of this course, students
should be able to:
1. Understand the application of basic principles of fluid mechanics including
fluid statics, kinematics and dynamics;
2. Demonstrate the knowledge of basic methods in analyzing various fluid flow
phenomena such as dimensional analysis;
3. Apply the methods to typical hydraulic problems such as flow in pipes and
open channel flow.
4. Follow the appropriate procedures to carry out laboratory activities to enhance
students’ generic skills.
