Part II 1.

Course Aims: This course aims to provide students with: (i) (ii)

2.

the fundamental principles of fluid science; and the application problem solving related to fluid mechanics.

Course Intended Learning Outcomes (CILOs) Upon successful completion of this course, students should be able to: No. CILOs Weighting* 1. solve basic problems of fluid statics. 1 2. solve problems of the fundamental principles of fluid flow. 2 3. apply principles of fluid flow in pipe flow and external flow. 3 4. predict relationship of parameters of fluid flow. 1 *Weightings are assigned to the CILOs according to their relative importance to the course (3 = most important).

3.

Teaching and learning Activities (TLAs) (Indicative of likely activities and tasks designed to facilitate students’ achievement of the CILOs. Final details will be provided to students in their first week of attendance in this course) Teaching pattern:

3 hours per week

Students are required to read the relevant reference books before each seminar session. A seminar is the major in-class teaching and learning activity in which lecturers would explain the selected topic by oral presentation, and would discuss with students through case problems, calculation exercises and real life examples. Students are required to generate/answer questions during a seminar session, and/or complete exercises after a seminar session. 1. A Pre-Class Study is a combination of selected reference books and/or lecture notes reading before each seminar session. 2. Seminar is an in-class activity in groups involving oral presentation by lecturers and discussion with students on a selected topic through illustrating exercises, real-life examples and question generation by the students and answering by peers or by the lecturer. 3. An Assignment is a combination of case problems and/or calculation exercises for guided students learning.

Assessment Tasks/Activities (Indicative of likely activities and tasks designed to assess how well the students achieve the CILOs. Final details will be provided to students in their first week of attendance in this course) Coursework: 40% Examination: 60%

Duration of examination: 2.5 hours

Note: A student must obtain a minimum mark of 35 in both coursework and examination and an overall mark of 40 to pass the course. 1.

An Assignment is a combination of case problems and/or calculation exercises for guided students learning. 2. A Test is in the form of multiple-choice questions and/or calculation problems and/or short questions. 3. An Examination may consist of multiple-choice questions and case/calculation problems.

Grading of Student Achievement (refer to “Grading of Courses in the Academic Regulations”) The grading is assigned based on students’ performance in assessment tasks/activities. Grade A The student completes all assessment tasks/activities and the work demonstrates excellent understanding of the scientific principles and the working mechanisms. He/she can thoroughly identify and explain how the principles are applied to science and technology for solving physics and engineering problems. The student’s work shows strong evidence of original thinking. He/she is able to communicate ideas effectively and persuasively via written texts and/or oral presentation. Grade B The student completes all assessment tasks/activities and can describe and explain the scientific principles. He/she provides a detailed evaluation of how the principles are applied to science and technology for solving physics and engineering problems. He/she demonstrates an ability to integrate taught concepts, analytical techniques and applications via clear oral and/or written communication. Grade C The student completes all assessment tasks/activities and can describe and explain some scientific principles. He/she provides simple but accurate evaluations of how the principles are applied to science and technology for solving physics and engineering problems. He/she can communicate ideas clearly in written texts and/or in oral presentations. Grade D The student completes all assessment tasks/activities but can only briefly describe some scientific principles. Only some of the analysis is appropriate to show how the principles are applied to science and technology for solving physics and engineering problems. He/she can communicate simple ideas in writing and/or orally. Grade F The student fails to complete all assessment tasks/activities and/or cannot accurately describe and explain the scientific principles. He/she fails to identify and explain how the principles are applied to science and technology for solving physics and engineering problems objectively or systematically. He/she is weak in communicating ideas and/or the student’s work shows evidence of plagiarism.
