There are certain basic structural mechanics concepts like units and dimensional analysis, centre of gravity and moments of inertia of objects, force and moments, vectors, equilibrium and stability, pressures which Civil Engineers must have at their fingertips. One of the aims of this unit is to make sure you have these.
In addition, the students should: learn the behaviour of fluids; be aware of the different ways of tackling a fluid mechanics problem, i.e. the place of theory, experiment, numerical modelling and dimensional analysis; be able to solve problems in hydrostatics, use principles of conservation to solve simple fluid dynamics, and use principles of similarity to explain fluid mechanics problems. To give students a thorough grounding in the fundamental principles of Fluid Mechanics as a pre-requisite for other advanced courses in open channel hydraulics, water and environmental engineering, hydraulic structures, and flood risk management.
At the end of this unit students should be able to:
1. Use confidently the relevant SI units to the common engineering variables and be able to assess the dimensional homogeneity of equations and basic problems;
2. Be able to calculate areas and volumes, centre of gravity and centroid, first moments;
3. Demonstrate knowledge of the concepts of force and moment, vectors, equilibrium and stability of objects; use Newton’s laws and describe the motion of systems;
4. Apply fundamental physics principles to a range of basic problems in the area of engineering mechanics.
5. Understand properties and behaviour of fluids;
6 Understand the variation of pressure with position in a fluid;
7. Determine the forces and moments on a surface or body due to hydrostatic pressure;
8. Explain the meaning of the metacentre and use it to determine qualitatively the stability of a floating object;
9. Understand the differences between laminar and turbulent flows;
10. Use the principles of conservation of mass, momentum and energy to solve simple, incompressible fluid dynamics problems;
11. Determine the forces on pipe systems due to flowing fluid;
12.Determine the force exerted by jets on surfaces;
13. Determine losses in pipe network systems;
14. Understand the concepts of stream functions, potential functions and flow net;
15. Use the principles of similarity and dimensional analysis in exploring real fluid phenomena and experimental analysis.
