Subject contents:

This subject will provide an introduction to fluid mechanics.Fluid viscosity and its properties shall be introduced. The study of hydrostatics and Archimedes’ principle. Conservation of mass, linear momentum, angular momentum and energy (Bernoulli). More advanced topics will include viscous fluid flow, Newton’s law of viscosity, Reynold’s number, laminar and turbulent flow. Use of the Moody diagram for internal pressure drop calculations. External flow and drag. Introduction to dimensional analysis and the Buckingham PI theorem.

Teaching and learning strategy:

There will be three hours of lectures every day covering the subject content.

Most classes we will have a ‘spot quiz’. This will be a short, 30 min to 1 hour, quiz on the present course materials. So please bring in pens, calculators and class notes (if you need them) for the quiz. Each quiz will count for 5% of your overall grade.

I will also send out practice problems. These are designed to help you understand the class notes and are for your own practice. They will help you enormously for the final exam. You do not have to hand these in and they will not be graded. If you cannot do a particular question we can talk about it in class or after class.

Final: A final three-hour written examination will be given on Monday July 18th 2016. All assignments, lectures, notes, work done on the board and reading assignments are considered examinable for the final exam.

Students are encouraged to communicate with the instructor directly or via email. Please feel free to share your opinions on course content, pace and difficulty. Questions in class are strongly encouraged as they give everyone the chance to learn interactively.
