Sample subject outline - Semester 2 2013

Note: Subject outlines often change before the semester begins. Below is a sample outline.

Rationale

Significant numbers of graduates are employed in local process industries such as in sugar processing, chemical and petroleum refineries and power generation plants. Graduates therefore need to have a thorough understanding of the principles of fluid mechanics and fluid dynamics. This is a design emphasis for areas of thermodynamics, fluid mechanics and heat transfer. Mechanical design has in the past and on most campuses concentrated on the design of machine elements. Employment of the majority of our graduates is in thermal process related industries and this subject is aimed at that type of design work.

Aims

This unit provides you with an introduction to the design methods applicable to process plant and particularly to piping systems and pressure vessel design.

Objectives

On successfully completing this unit you should be able to:

1. Calculate the performance and design criteria for cooling towers


2. Design pressure vessels such as heat exchangers according to relevant codes


3. Assess/modify/design a piping system which could include control valves, multi-pump operation, branched pipe-work, pipe supporting systems and pipe-work stresses (including applications to slurries)

Content

1. Cooling tower
a. Theory of cooling towers
b. Selection and sizing of cooling towers
2. Heat exchangers and pressure vessels
a. Overall system concepts (cycle components, specifications, heat balance)
b. Mechanical design of piping systems (process, thermal and dynamic analysis)
c. Case study: (i) condensing & feed heating plant, (ii) heat exchanger sizing, (iii) power stations
3. Industrial Piping Systems
a. Valve types, construction and selection
b. Design consideration for industrial piping systems (pipe sizing, slurry piping design)
c. The pumped system (system resistance, matching pumps to system, multi-pumps, networks)

Approaches to Teaching and Learning

Teaching Mode
Hours per week: 4
Lecture: 2 hrs/wk
Tutorial: 1 hr/wk
Practical sessions and site visits: 1 hr/wk equivalent

A total of fifty-two hours is devoted to lectures, tutorials and field visits. Emphasis is placed on design activities facilitated by industry specialists from professions that deal with thermofluid plant design on a daily basis. Various site visits will enable you to reinforce the concepts in plant and process design taught in the classroom.

Assessment

The assessment in this unit is designed for you to:

• problem solve key effects of mechanical noise and vibration in industry,


• conduct practical experiments to test and analyse results,


• report well supported findings using professional tools, standards and criteria.

Because of the emphasis on problem diagnosis and solving as well as application and analysis, the assessment is weighted 60% for practical work and reporting and 40% for the final exam.To let you know how you are progressing throughout the unit, you will receive oral feedback during tutorial discussions throughout the semester. The written feedback you receive on your first assessment item in mid-semester will provide valuable guidance on issues you may need to address. The second report is due at the end of semester. Feedback to prepare for the exam will be provided in lectures and tutorials before the exam.

Risk assessment statement

You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.

You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).

You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.

Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
