    Course Introduction
    An understanding of the underlying physics and mathematical description of fluid mechanics is necessary to analyse systems that have a fluid as the working medium.  Mechanical engineers have to deal with fluid mechanics in applications ranging from heating and ventilation systems, transport of fluids in piping systems, fluids in physiological systems, through to transport applications such as cars, ships, aircraft and spacecraft.  The design of fluid machinery such as pumps, compressors and turbines requires the ability to analyse fluid flows.  This course builds on material in MECH2410: Fundamentals of Fluid Mechanics and applies it to viscous internal and external flows, compressible flows, turbo machinery and biomedical applications. Whilst fluid flows must satisfy the well-established basic laws of mechanics, the analysis can become very complex and experimental results must often be used to model practical flows. Therefore the importance of making measurements in fluid flows is also stressed in this course.  Some methods and techniques used to make measurements in fluid flows are addressed together with an assessment of their uncertainty.

    You should plan to spend at least 12 hours per week on this course in order to obtain a passing grade.
