Course description and aims

In the experiments on hydraulics, students will obtain a deeper understanding of fundamental principles regarding water flow which have been studied in lecture. The four different experiments were conducted, namely “water flow in pipe line”, “water flow in open channel”, “water flow on the weir” and “water wave”. In the end of experiments, student will have the PET bottle rocket contest, where students will design and create their original rockets based on the fluid dynamics. In the experiments on hydraulics, students’ performance will be evaluated by three activities: (i) “interview prior to experiment” where students’ background knowledge on hydraulics will be checked if they already have sufficient knowledge to conduct the experiment, (ii) “experiment” where students’ attitude and leadership will be considered during the observation and measurement of various phenomena relevant to water flow and (iii) “interview after the experiment” where students’ understanding on the experimental results and analysis will be evaluated.

Student learning outcomes

By the end of this course, students will be able to:
1) Measure, analyze and discuss the water flow on weir including characteristics of water pressure and velocity in the potential flow.
2) Measure, analyze and discuss the theory and characteristics of water wave including water height, velocity and orbital of water particles.
3) Measure, analyze and discuss the resistance occurring in the turbulence flow and laminar flow in circular pipe
4) Measure, analyze and discuss open channel flow including hydraulic jump and water flow around the cylinder-shaped material.
5) Independently and creatively make a PET bottle rocket based on fluid dynamics.

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

In the experiments on hydraulics, (i) interview prior to experiment, (ii) demonstration of experimental equipment and procedure, (iii) experiment and (iv) interview after the experiment will be conducted for each experiment. In addition, PET bottle rocket contest will be conducted after the two experiments were completed.
