| Module Overview |
|
Material in fluid mechanics common to Civil, MMA and Chemical Engineering is delivered in the 1st Semester.
The basic concepts underlying fluid flows and behaviour are described together with simple fluid properties. The calculation of static fluid forces is the starting point before moving to dynamic fluid effects including mass-flow and energy continuity.
The Civil Engineering specific material is delivered in the 2nd semester.
Pipe flow and the associated energy losses in pipe fixtures and fittings are studied in this semester. The laws governing pipe flow are explained and then applied to basic pipe flow applications. The work is extended to cover more advanced pipe networks and reservoir problems.
Knowledge of wind engineering is essential for estimating its effect on stationary (buildings and structures) and moving (road vehicles, rail and pedestrian comfort) objects. This part of the module introduces the basic concept of wind engineering. It enables students to understand wind characteristics, loading codes, flow and turbulence in an external environment and apply this knowledge to determine wind loads on real objects.
