CVEN20130 Hydraulics I

Academic Year 2020/2021

This module is a foundation course in Civil Engineering hydraulics and presents fundamental principles that will be further developed in subsequent years of the course. The course will take place in Autumn and will and will consist of 12 x 2 lecture/ tutorial sessions (for all students). The module will be supported by the provision of course material in Brightspace and students will be expected to work through this material in advance of lecture/ tutorial sessions. An end of trimester examination will be included in the module assessment. The syllabus will commence with important definitions, notation, fluid properties and methods for visualising fluid flow. Hydrostatics is the study of fluid at rest and the analysis of forces, frequently specified in terms of pressure, on submerged bodies and other surfaces will be explained and investigated. Cases of buoyancy and the stability of floating objects will also be analysed. Differences between ideal and real fluids are important in hydraulics and will be covered. The syllabus will develop to include situations where fluid is moving (rather than being static) in both closed conduits (pipes) and open channels (rivers and streams). The types and classifications of these flows will be presented. The fundamentals of fluid flow that include continuity (mass conservation) together with the Bernoulli (and energy) and momentum equations will be presented and applications of these will be explained using engineering examples. The course will be limited mainly to steady flow cases in open and closed conduits with more complex flow types and systems being covered in the Stage 3 Hydraulics II module. Understanding friction (and other energy losses) in these hydraulic systems is important and ways of representing frictional effects will be presented. Worked examples are again used to develop these principles.

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.

Approaches to Teaching and Learning:
A blended learning approach will be used in the delivery of this module. Course material will be provided to students using the Brightspace VLE and will be independently studied by each student. Important theoretical components will be presented in the lecture/ tutorial sessions but these largely, will be underpinned by active learning interventions requiring student input and engagement such that real world-problems in hydrostatics, closed conduit flow and open channel hydraulics can be explored through enquiry and problem-based learning. Argumentation and debate will be encouraged. The learning approaches will promote the development of critical thinking skills and dispositions in students.
