• This unit may be delivered over 24 weeks (2 Terms) because the nature of the content is deemed suitable (from a pedagogical perspective) for a longer duration than the standard 12 week (1 Term). In addition, these 24-week duration Units require half the student workload hours, 5 hours per week, which allows the total load to be kept at 15 hours per week when combined with a typical 10 hours per week, 12-week Unit. EIT has extensive data to demonstrate that if the load is higher than 15 hours per week the attrition rate for part time students dramatically increases.

  The objective in presenting this unit is to provide students with detailed knowledge of the principles and practices governing the field of fluid mechanics.

   

  The unit will include: basic fluid properties and laws governing fluid statics; principal concepts and methods of fluid kinematics and dynamics; fluid system flow analysis utilising the Continuity, Bernoulli, and Momentum equations; flow system analysis including boundary layer concepts and modelling based on dimensional analysis. Students will also undertake a project work involving dimensional analysis and modelling.

   

  At the conclusion of this unit, students will have been imparted with the requisite knowledge to comprehend, distinguish, and apply the principles and practices governing the field of fluid mechanics in their future work.
