    Course Introduction
    This course introduces students to basic principles of fluid and particle mechanics relevant for industrial practice, and focuses on applied calculations. Most engineering industries rely on effective flow of fluids and particles, as well as efficient contacting between fluids and solids. Therefore, this course is a significant course for chemical, materials, and mineral process engineering disciplines. Learning from this course will be applied in many other courses in all disciplines.


    Learning Objectives
    After successfully completing this course you should be able to:

    1.1  Engineering knowledge: explain important definitions and correlations relevant to fluid and particle mechanics, and classify a new complex problem solution in the fluid &particles interaction using learnt knowledge.
    1.2  Complex evaluating: determine whether the equations /models in fluid statics, Bernoulli equation, pipe flow calculations, pump specification, particle settling, packed beds or fluidised beds are better suited to a specified application and justify your selection
    1.3  Engineering process: use fluid & particle interaction principals to design reactor systems that involve the fluid & particles interaction and pumping system, predict the behaviour of your systems and make recommendations for specific applications
