| Summary | The student should develop an awareness of the qualitive behaviour of fluids in typical situations so that models of problems can be set up for solution. The course's objectives are to:
1. Produce quantitative solutions for models derived from some useful applications in the fields of measurement and pipe flow;
2. Establish enough theoretical background to enable the range of validity of these basic solutions to be understood; and to
3. Provide a starting point with respect to terminology and theory for more advanced study in subsequent years.

Laminar and turbulent flow states; flow in a duct, flow over a flat plate; flow round objects; separation & wakes; vortex shedding; drag.
L3 Simple Flow Fields and Phenomena 2
Reynolds number; Strouhal number. More simple flow fields; orifice flow, flow round bends. Terminology: external/internal; steady/transient, real/ideal, laminar/turbulent, compressible/incompressible; vectors, streamlines & pathlines.
L4 Introduction to Dimensional Analysis
L5 Fluid Statics 1
Pressure; variation of pressure with height; 'head'; manometers and other pressure measurement devices.
L6 Fluid Statics 2
Forces on submerged surfaces - 'centre of pressure', 'centre of force'.
L7 The Continuity Equation
The continuity equation; flow between plane walls. pipe flow.
L8 Equations of Motion
Equation of motion along a streamline; steady-state equation (Euler's momentum equation); motion perpendicular to a streamline - significance of pressure gradients.
L9 Bernouilli¿s Equation
Time dependent Bernoulli equation; Steady state Bernoulli equation.
L10 Applications of Bernouilli
Example applications of Bernoulli equation: siphons, flow with area change, flow around a pipe bend.
L11 Velocity and Flow Rate Measurement
Pitot tube & Pitot-static tube. Flow rate measurement - restriction flow meters (general); venturi meter.
L12 Hydraulic Structures
Orifice plate; reservoir-orifice flow; linked reservoirs; orifice flow under varying head; flow over weirs.
L13 Laminar and Turbulent Flow
Laminar flow between plates. Laminar flow through a round pipe - Hagen Poiseuille equation.
L14 Turbulent Flow in Pipes
Head/pressure losses due to friction; friction coefficient - functional dependency via dimensional analysis.
L15 Losses in Real Pipes
Moody diagram & equation.
L16 Pipe Systems
Losses in bends and fittings; loss coefficient.
L17 The Momentum Equation
The momentum equation for steady flow.
L18 Applications of the Momentum Equation

Learning Outcomes
On completion of this course, the student will be able to:
- Categorise, qualitatively describe, and recognise the engineering consequences of important fluid flow situations, including hydrostatics, internal and external flows; laminar and turbulent conditions; boundary layers; velocity profiles; separation and wakes.
- Understand physical basis of Bernoulli's equation, its consequent limitations, and apply it to a variety of practically-useful engineering problems including flow measurement.
- Solve basic problems involving energy losses through pipe systems.
- Understand the basic Momentum equation and the concept of a control volume, and be able to apply it to a variety of practically-useful situations including jet reaction forces.
- Gain key data handling and reporting skills in graph plotting, handling of experimental uncertainty, and in drawing sound, concise conclusions supported by clear and quantitative evidence.
