## Description

The main part of this course will provide a basic understanding of the behaviour of fluids on the macro- and micro-scale, where students are able to design pipe and pumping systems for single-phase fluids. There is also an introduction to the SI system of units, dimensional analysis and scale-up.

Basic concepts: fluid mechanics, liquids and gases, pressure/stress/force/mass, properties of fluids (viscosity, surface tension)

The unit systems: for chemical and process engineering and unit conversions

Dimensional analysis: the variables used in chemical and process engineering systems

Static systems: pressure, manometry, atmospheric pressure, barometry, buoyancy

Dynamic systems:
• Bernoulli’s equation: applications of Bernoulli to flow measurement, including pitot tube, orifice, venturi, weir and rotameter
• Friction
• Pipe flow: laminar flow, turbulent flow, velocity profiles, pressure losses in pipes and fittings, non-circular ducts, double integrals to determine area

Scale up

Pumping
• Pumps: pump sizing, net positive suction head, complete system design
• Control of flow with valves and variable speed
• Pipe networks
• Optimal pipe diameter and economic analysis

Drag

Compressible flow

Special topics

## Learning Outcomes

At the completion of the course students will be able to
1. Convert one set of units to another commonly encountered in chemical engineering.
2. Carry out calculations for fluid mechanics involving static pressure, pipe flow profiles and pressure drop, pumping and other related topics.
3. Understand different types of flow measurement.
4. Have a practical understanding of uncertainties as seen in a laboratory flow system.
5. Work as a team for the creative design of a “water feature” and for lab work and reporting.
6. Write professional reports for an appropriate audience
7. Be proficient at using Excel for fluid mechanics calculations.
8. Interpret and design systems with flows

## Assessment

Assessment Due Date Percentage  Description
Final Exam 55%
Lab 1 5% Civil engineering fluids lab (5%, group report) due 1 week after the lab, 5pm
Assignments 13 Mar 2020 5% Assignment 1 - Unit conversions, viscosity, fluid statics, due Friday March 13th, 5pm
Test 27 Mar 2020 20% A 50 minute test on content taught in weeks 1-6 will be held on Friday the 27th of March.
Assignment Two 15 May 2020 5% Assignment 2: Pumps, complete systems and compressible flow due Friday 15th May.
Lab 2 29 May 2020 10% Water feature group project (10%) broken in to milestones 1%, project scoping 1%, final design 3%, WF demonstration 5%, Report due 29 May

Course Policies on Collaboration and Cheating
Solving problems in small teams and collaborative learning when working on assignments is encouraged.  However direct copying will result in reduced or zero marks for all students involved.  The assignments are mainly a tool to prepare you for the exams. We advise you to try them individually before collaborating in groups.

Course Requirements
Both labs must be attended to pass the course. Both lab reports must be handed in and completed to a satisfactory standard to pass the course.  Each student must sign submitted lab reports. Late reports and assignments will be penalised 10% per day after the due date.

Laboratories
Fluid Flow Lab: There will be one afternoon for each student to investigate pumping and flow measurement in the Civil Engineering Fluids Laboratory in Term 2.  Students will work as a team.  A group report will be required.

Water Feature
During Term 2, students will work in groups of 5 or 6 to design and build a water feature.  In the last week of the semester, each group will demonstrate their water feature.  A group report will be required.

Missing units in answers unless these are dimensionless
Zero points will be given to the problem
