Learning Outcomes:
On completion of this module, students should be able to: (1) describe the characteristics of a fluid and explain what different fluid properties mean; (2) distinguish between the properties of different fluids; (3) apply hydrostatic and force balance relationships to solve problems in stationary fluids; (4) differentiate between laminar and different types of turbulent flow; (5) classify flows in terms of how parameters vary with time and distance; (6) formulate the conservation laws of fluid flow; (7) analyse closed conduit and open channel hydraulic systems to apply these laws and determine parameter values for steady uniform flow situations; (8) demonstrate that you understand the role of friction in open channel and closed conduit hydraulic systems; (9) calculate energy losses in closed conduits; (10) design a closed conduit hydraulic system to convey a specified flow at a given pressure; (11) plan and conduct experiments, analyse and interpret the results and write up your findings in a coherent and logical manner.
Indicative Module Content:
This module introduces fundamental concepts in fluid mechanics/ hydraulics for civil engineering students. Subject matter is presented in a progressive way from simple to more complex and is supported throughout by numerical examples that illistrate the use of basic principles. The properties we use to describe fluids are initially introduced as are the units and measurement of these properties. The understanding of presssures, forces, floatation/ buoyancy in static fluid systems (hydrostatics) are then dealt with. The course then progresses to dynamic or moving fluid systems. Visualising fluid systems through the use of stramlines, pathlines and streaklines is introduced. The Euler and Bernoulli equations are developed and examples of how these equations are applied are introduced to students. The fundamental laws of mass, energy and momentum conservation are subsequently introduced and applied to closed to closed conduit and open channel systems. Hydraulic resistance and energy dssipation in these systems underpins the analysis.
