Assessment

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).


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 25% 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 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.

Notes

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.

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

RELATION TO OTHER COURSES
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

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

Resubmissions

To be submitted to the course coordinator

Where to submit and collect work
