### Synopsis

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.

### Outcomes

On successful completion of this unit students should be able to:

• calculate fluid forces acting on bodies that are partially of fully submerged in a quiescent fluid or a fluid undergoing rigid body motion
• calculate solutions to flow problems employing Bernoulli's equation
• solve fluid flow problems by employing the concept of control volumes to predict fluid behaviour with particular regard to the principles of continuity and momentum
• employ dimensional analysis and modelling to plan experiments, present results

meaningfully and predict prototype performance

• calculate lift and drag forces for bodies subjected to fluid motion
• distinguish 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
• compute flow rates and pressure drops in pipe networks under steady state conditions
• employ knowledge of the typical operation, limitations, operating parameters and

applications of turbo-machines to evaluate the selection of appropriate turbo-machinery for a range of pipe networks and/or flow conditions

• describe current flow measurement techniques employed in research and industry
• calculate the lift and drag on vehicles of different geometries travelling at a variety of speeds and to determine the consequent effect on vehicle performance

### Assessment

Continuous assessment: 40%
Examination (3 hours): 60%
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.
