This will be your best selfevaluation to see whether you understand the concepts. 7 Assessment Test 1 (Part 1): 25% 27/09 (Week 7) Monday 2:00-3:30pm via ZOOM Contents in Test 1: 1. Fundamental Concepts, 2. Dimensional Analysis, 3. Fluid Statics Test 2 (Part 2): 15% Final Exam: 60% open-book open-note for tests and final exam 8 Learning Outcomes On successful completion of this module, you are expected to be able to: 1. Apply dimensional analysis to obtain dimensionless groups for the physical phenomenon, and model theory to predict the behaviour of a system from its dynamically similar system 2. Explain and find the pressure in static fluids 3. Apply finite and differential control volume approach of the continuity, momentum and energy equations to solve various fluid flow problems 4. Describe the concept of inviscid flow and stream function 5. Examine viscous flow in momentum boundary layer around an immersed object 6. Perform calculation for a centrifugal pump in a piping system 9 Suggestions • Have confidence in doing well • Keep up with reading • Do not memorize but try to understand “One has to have persistence, but above all else belief in oneself.” “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.” Marie Curie (1867-1934, Polish-French physicist-chemist, Nobel Prize of physics in 1903 and of chemistry in 1911, 1st woman to win a Nobel Prize, the 1st person and the only woman to win the Nobel Prize Twice) 10 • Ask question • Work on assignment • Discuss collaboratively “Coming together is a beginning. Keeping together is a process. Working together is a success.” Henry Ford (1863 – 1947), the founder of the Ford Motor Company. He is credited with "Fordism", that is, the mass production of large numbers of inexpensive automobiles using the assembly line, coupled with high wages for his workers.
