Aims
This module aims to introduce the fundamental principles of fluid mechanics and to lay a solid foundation for subsequent work involving civil engineering hydraulics and water engineering.
Learning outcomes 
A. Understand the nature of fluids, units and dimensions associated with Fluid Mechanics problems.


B. Understand the scientific principles of hydrostatics in terms of pressure distribution, action of forces to submerged bodies and stability of floating bodies


C. Understand the fundamental hydrodynamic equations (continuity equation, Bernoulli’s equation, momentum equation) and apply them to simple flow-measuring devices.


D. Understand fundamental concepts, terms and measuring devices related to open channel flow

E. Demonstrate compliance with the health and safety procedures associated with laboratory work



Method of teaching and learning 
The material in this module is delivered through a combination of formal lectures, tutorials and supervised practical sessions. General transferable skills are developed through the presentation of written and oral reports.
