Studying online

There are now 3 possible online modes for units:

Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.

Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus due to COVID border closures. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA and include which of the below criteria applies:

  • You are a student who is currently offshore and unable to enter Australia.
  • You are a student in Australia who is impacted by state or regional border closures.

CHPR4405 Particle Mechanics and Solids Handling

6 points
(see Timetable)
Semester 1OnlineOnline timetabled
Semester 1UWA (Perth)Face to face
Topics include particle size reduction and separation; sampling and particle size analysis; screening and classification via hydrocylcone; particle drag, sedimentation, gravity thickening and thickener sizing; froth flotation, flow-through packed bed and filtration; fluidisation; colloid behaviour and properties, DLVO interaction theory, rheometry, slurry rheology and its relationship with surface chemistry, bridging flocculation and surface forces; pipeline transport of non-Newtonian fluids; powder flow and stability
Students are able to (1) work effectively in teams; (2) write clear and concise technical reports; (3) perform a laboratory experiment to discover knowledge on flow behaviour of suspensions; (4) distinguish between particle sizing and classification; (5) apply surface chemistry technique to optimise suspension processing; (6) apply surface chemistry to control surface force between particles; (7) explain and use the equations governing leaching kinetics, filtration, suspension thickening, fluidisation and pipeline transportation; (8) apply surface chemistry to froth floation; and (9) quantify the number of countercurrent stages required to achieve a given degree of washing of solids.
Indicative assessments in this unit are as follows: (1) laboratories and assignments; (2) tests; and (3) final examination. Further information is available in the unit outline.

Supplementary assessment is only available in this unit in the case of a student who has obtained a mark of 45 to 49 and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

Unit rules
enrolment in the Master of Professional Engineering (MPE) (Chemical Engineering specialisation or Mechanical Engineering specialisation)
Advisable prior study:
for MPE Chemical Engineering specialisation: ENSC3003 Fluid Mechanics and ENSC3005 Mass and Energy Balances (co-requisite: ENSC3007 Heat and Mass Transfer); for MPE Mechanical Engineering specialisation: ENSC3003 Fluid Mechanics (co-requisite: ENSC3007 Heat and Mass Transfer)
  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
