Undergraduate - UnitCHE2161 - Fluid mechanics

Refer to the specific census and withdrawal dates for the semester(s) in which this unit is offered.

Synopsis

An introduction to momentum transfer. Topics include fluid statics; differential and integral balances of mass, momentum and energy; flow measurement; pipe flow and frictional losses; dimensional analysis; pumps; compressible flow.

Outcomes

1. Calculate fluid forces acting on bodies which are partially or fully submerged in fluids.
2. Use control volumes to predict fluid behaviour with particular regard to the principles of continuity, momentum and energy, and the Bernoulli equation.
3. Use dimensional analysis and modelling to plan experiments, to present results meaningfully and to predict prototype performance.
4. Calculate lift and drag forces for bodies subjected to fluid motion.
5. Compute flow rates in pipe networks under steady state conditions.
6. Understand the typical operation and applications of Pumps and Compressors, their capabilities and limitations, and operating parameters that significantly affect performance
7. To describe the nature of two-phase flows and to use simple models for prediction of pressure drops in such flows
8. To classify non-Newtonian Fluids, use constitutive equations for these fluids to predict pressure drops in different flows
9. Carry out simple experiments relating to fluid properties and flow behaviour.

Assessment

Assignments: 30%
Examinations (3 hours): 70%
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.
