This unit develops the students' physical understanding of fluid statics and fluid flow and the interaction of fluid forces with solids.

Topics include hydrostatics, Reynolds transport theorem, continuity and momentum equations, control volume analysis, the Bernoulli equation, viscous pipe flow, pumps, dimensional analysis, boundary layers, flow measurement techniques and applications of fluid forces in flow - lift and drag.


At the successful completion of this unit you will be able to:

  1. Determine and solve fluid flow problems by employing Bernoulli's equation and control volumes to predict fluid behaviour with particular regard to the principles of continuity and momentum.
  2. Use dimensional analysis and modelling to plan experiments, present results meaningfully and predict prototype performance.
  3. Determine lift and drag forces for bodies including vehicles subjected to fluid motion.
  4. Analyse and discern between laminar and turbulent flows, demonstrate an understanding of boundary layers and flow separation, and explain how these concepts impact on drag and fluid energy loss.
  5. Determine the appropriate sizes and operating parameters for turbo machines by employing knowledge of the typical operation, limitations, and applications of these devices.


Continuous assessment: 50%

Examination (2 hours): 50%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

3 hours lectures, 3 hours of laboratory/problem solving classes and 6 hours of private study per week
