Units, dimensional analysis, measurement, errors, report writing and fluid mechanics.

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

The SI system for chemical and process engineering and unit conversions.
Dimensional analysis of the variables used in chemical and process engineering systems.
Static systems: pressure, manometry, atmospheric pressure, barometry.
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
• 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.
Buoyancy and drag.
Compressible flow.
Introduction to Microfluidics.

Learning Outcomes

At the completion of the course students will be able to
1. Convert old units to SI for quantities 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. Work as a team for the creative design of a “water feature” and for lab work and reporting.
5. Write professional reports for an appropriate audience
6. Be proficient at using Excel for fluid mechanics calculations.
7. Have a practical understanding of uncertainties as seen in a laboratory flow system.

Assessment Due Date Percentage  Description
Assignments 10% 2 Assignments worth 5% each : Assignment 1 - Unit conversions, viscosity, fluid statics, due Friday March 16th, 5pm Assignment 2 - Dimensional analysis, pipe networks, complete systems, due Friday 18th May, 5pm
Final Exam 55%
Laboratories 15% There are two lab components in this course. Attendance to both is compulsory, and each group member must sign the submitted report. 5% Civil Engineering fluids lab (group report) due 1 week after the lab, 5pm 10% Water feature group project (group report) due Friday 1 June, 5pm Peer assessment will be used in both groups to generate an individual grade for each student.
Test 26 Apr 2018 20% A 90 minute test on content taught in weeks 1-6 will be held on Thursday 26 April. You will need a calculator for this test (stickered calculator is not required).

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 25% per day after the due date.

Fluid Flow Lab: There will be one afternoon for each student to investigate pumping and flow measurement in the Civil Engineering Fluids Laboratory in the second term.  Students will work as a team in groups of 5 or 6.  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.

Recommended Reading

Holland, F. A. , Bragg, R; Fluid flow for chemical engineers; 2nd ed. ; Edward Arnold, 1995 (This text is also recommended for ENCH393).


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.

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

This is a core chemical engineering course and is a prerequisite of ENCH393.

Additional Course Outline Information

Assessment and grading system

All assessment marks might be scaled to ensure that a reasonable range of grades is obtained when the University Grading Scale is applied.  Students should not rely on their raw marks.  A mark of 40% in the exam is required to pass this course.

Late submission of work

Late submissions will lose 25% grade per day overdue.

Requests for extensions
