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, 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 Pumping • Pumps: pump sizing, net positive suction head, complete system design• Control of flow with valves and variable speed Pipe networksOptimal pipe diameter and economic analysisBuoyancy and dragCompressible flow Introduction to Microfluidics
Course ObjectivesAt the completion of the course students will be able to1. 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 audience6. Be proficient at using Excel for fluid mechanics calculations.7. Have a practical understanding of uncertainties as seen in a laboratory flow system.

ConcernsStudents with concerns about the course should contact the course coordinator, (Anne Gordon), director of 1st Pro Studies (Ken Morison), or the Head of Department (Prof. Peter Gostomski).
Course RequirementsBoth 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.LaboratoriesFluid 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. 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.
This is a core chemical engineering course and is a prerequisite of ENCH393.
Course Policies on Collaboration and CheatingSolving 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.General Policies of the DepartmentStudents 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
Assignments (10%)Two assignments will be given out throughout the semester and will be supported by tutorials. The assignments are to be handed in to assignment boxes on the 4th floor of the Link building (CAPE academic offices) 5% Assignment 1 – Unit conversions, viscosity, fluid statics, due Friday March 15th, 5pm5% Assignment 2 – Pumps, complete systems and compressible flow, due Friday 17th May, 5pm 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, 5pm10% Water feature group project broken in to milestones: 1% project scoping due Friday May 3rd, 1% Final design due Friday 10th May, 3% WF demonstration Tuesday 28th May, 5% design report due Friday 31st May, 5pmPeer assessment will be used in water feature project to generate an individual grade for each student. Test (20%)A 90 minute test on content taught in weeks 1 – 6 will be held on Tuesday 2nd April. You will need a calculator for this test (stickered calculator is required).Final Examination (55%)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 submissions will lose 25% grade per day overdue.
