FLUID MECHANICS I (SKMM 2313 / SEMM 2313)


  • COURSE INFORMATION

    Open or Close
    The principle aim of this course is to provide students with an understanding of the properties of fluids and to introduce fundamental laws and description of fluid behavior and flow. It will emphasize on the concept of pressure, hydrostatic pressure equation and its application in the measurement of pressure, static force due to immersed surfaces, floatation and buoyancy analysis. Dynamic flow analysis inclusive of technique in solving flow problems is introduce especially to solve flow measurement, mass or volumetric flow rate, momentum in flow and loss in pipe network. Lastly, some basic dimensional analysis and similarities will be introduced. At the end of the course, the student should be able to demonstrate an ability to analyze whether statically, dynamically or kinematically problems related directly to fluids.

    COURSE LEARNING OUTCOMES
    1. Calculate and analyse shear stress in fluids flow, the pressure difference in manometer, hydrostatic forces on plane and curved surfaces, buoyancy force and stability of submerged and floating bodies.
    2. Calculate and analyse fluid dynamics problems using integral forms and differential forms of three basic laws: Bernoulli, energy and momentum equation.
    3. Categorize, calculate and analyse the major and minor losses for laminar and turbulent flows in pipes and pipes systems.
    4. Derive the dimensionless parameters for a given flow problem using dimensional analysis and similitude in order to solve various problems related to modelling.
