This unit builds on Fluids Mechanics 1 that was covered in Semester 1 (it is also a pre-requisite). Fluid mechanics provides the theoretical foundation for hydraulics, which focuses more on the engineering applications of water and other liquids. Hydraulic topics covered in this unit include practical applications in open channel flow, such as hydraulics structures, flow measurement, river channel behaviour, erosion and sedimentation. These topics would be taught using practical hand-on lab experiments, lab demonstrations and a computer based assignment. The site visit is designed to improve the student’s ability to link theory (learnt in the classes) with practical real-world situations.
Pipe flow, boundary layer theory, water hammer; Open channel flow, discharge equations for uniform flow, Specific energy and critical depth, flow transitions and hydraulic jump; Gradually varied flow, classification, water surface profile evaluation; Dimensional analysis, dimensional homogeneity, Rayleigh and Buckingham pi methods, hydraulic model studies; Hydraulic structures, culverts, broad crested and crump weirs; Flow measurements, venturi meter, orifices, sharp crested weir; River hydraulics, river sediment transport and movable bed forms, estimation of sediment loads, reservoir saltation and loss of capacity, river training and control, bank stabilisation and channel maintenance.
On successful completion of this unit, students will be able to:
