Description

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 will also be unit conversion, 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
Effects of temperature and pressure
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.

Six tutorial sessions.

Course Coordinator / Lecturer

Heon Park

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 point will be given to the problem

Notes

Concerns
Students may obtain the general policies of the University from the website. For example:

Special considerations: http://www.canterbury.ac.nz/study/special-consideration/  

Academic Appeals of Assessments: Students with concerns about assessment processes or grades should be advised to speak first with the relevant lecturer or the course coordinator. If the matter cannot be resolved, then the student should meet the 2nd year Director. If the matter still cannot be resolved, the student should discuss the matter with the Head of Department/School and thereafter follow the procedures outlined in the University procedures http://www.canterbury.ac.nz/media/documents/postgraduate-/Academic-Appeals-Grievances-Principles-Procedures.pdf  and regulations https://www.canterbury.ac.nz/regulations/general-regulations/academic-appeals-and-grievances/

Reconsideration of grades: If you are concerned that your final grade may be incorrect, it is suggested (for CAPE) that you make an informal query to the course coordinator, but you may follow the official procedures: http://www.canterbury.ac.nz/study/examinations/result-dates-and-appeals/

Disabilities: http://www.canterbury.ac.nz/disability/

Relation to Other Courses
This is a core chemical engineering course and is a prerequisite of ENCH393 in the 3rd year.

Course Requirements:
Submission of all assignments, lab reports, and exam is mandatory to pass this course.

Additional Course Outline Information

Academic integrity

Course Policies on Collaboration and Cheating
Solving problems in small teams and collaborative learning when working on assignments is encouraged.  However, partial or full,  direct copying sources from peer or literature will result in zero mark for the assignment. Students, who provided or shared their findings (raw data, solutions, etc.), will fail this course.
The assignments are mainly a tool to prepare students for more complex problems. We advise you to try them individually before collaborating in groups.

General Policies of the Department
Students may obtain the general policies of the University on matters such as special consideration applications, appeal procedures, reconsideration of grades and special provision for students with disabilities from the University Calendar

Lab Reports
There are two lab components in this course.  Attendance to both is compulsory, and each group member must sign the submitted report.

Assessment and grading system

Grade
All assessment marks might be scaled to ensure that a reasonable range of grades is obtained when the University Grading Scale (https://www.canterbury.ac.nz/study/grading-scale/) is applied.
Students should not rely on their raw marks to estimate the final grade.
At least 40% of the total mark of the exam and a lowest grade of C- are required to pass this course.

Attendance

Not mandatory but encouraged.
Lectures will be video-recorded, and the videos will be available up to two weeks from the lecture time. However, the technical quality of the videos will be not guaranteed.

Late submission of work

Late submissions will lose 10% of total mark of given assignment per day overdue.

Requests for extensions

To be submitted to the course coordinator, or see Department policy on Special Consideration

Resubmissions

To be submitted to the course coordinator.

Where to submit and collect work

CAPE reception, 4th Floor Link building, or to Learn (as directed)

Indicative Fees

Domestic fee $986.00

International fee $5,500.00

* All fees are inclusive of NZ GST or any equivalent overseas tax, and do not include any programme level discount or additional course-related expenses.
