Department of Mechanical Engineering Level: Semester four (S4) students Work-Preparedness Assignment 1 Group Assignment: consist of design, construction, commissioning, presentation and technical report.

INTRODUCTION Before the National Diploma may be awarded, the student is required to undergo 12 months of relevant experiential learning in addition to the 24 months of theoretical studies at the University of Technology. The student must therefore attend Work-Preparedness class to familiarise them selves with type of project to expect in the industry. During this period the student should be engaged in all required core workplace learning areas and will be responsible to liaise, in respect of progress, guidance and submission of the reports.

 * Task: ** design and installation of the pump system that will transport water available at sea level (in Camps bay) to a height 1.3km above sea level (on top of Table Mountain). Water will be transported over a distance of 2.1km.

This group project consists of a maximum of four members. The students are required to do a feasibility study on how to design a system that shall include multiple functions to make optimal use of the water. The students are requested to do a feasibility study on how to design the product, come-up with conceptual design, design and develop the product, implement or construct the product, and do commissioning and handover of the product.

Once the students have completed the pump system’s design, as per the per the requirement set out below, they are requested to write a report on their proposed solutions, which they are going to present to the senior management and lecturer, to ensure that system will meet all the criteria and safety features required to protect the equipment. Apart from calculations to show that the pump and selected pipe system will be able to perform this duty, they requested to also show the proposed cost for the materials and equipment as far as possible with justifications for their selected designs or choices.

The report layout must be according to Appendix H encompassed below. At the completion of this project the student should have covered the following subject areas: Students should explain how they approached the problem and justify their choices.
 * Plant Optimisation
 * Process Control in a Manufacturing environment
 * Quality Assurance
 * Draughting and Design
 * Basic electrical and Electronics Technology
 * Application of Thermodynamic Technology
 * Maintenance Applications
 * Application of Fluid Mechanics Principles
 * Strength of Materials applications, including the identification of the properties of engineering materials


 * Problems to consider and solve **
 * Students are may consider using multistage centrifugal pump for this type of the design. They may select a pump that will overcome a suction head, while the pump is operating at or close to optimum efficiency.
 * Students might have to decide between 100mm and 150mm NB pipe in terms of efficiency. Students have a choice between flanged steel and concrete pipe, should choose and explain why that choice.
 * Students are expected to calculate their designs. And should explain how many metres of pipe lines they are going to require for the design.
 * How many standard fitting would the students need for the proposed layout?
 * What are the losses due to the line and fittings – are the fitting considered above good enough to operate the system efficiently. Maybe students might have to consider shut-off for repairs and maintenance, reduced flow, flow/pressure readings, waterhammer, pump protection, etc.
 * Should indicate how much material/equipments are going to be purchased to build the installation. Student should consider the line’s operating pressure to calculate or select wall thickness.
 * How would students protect the pump against physical damage that could be caused by solid objects (metal or small rocks) being fed into the reservoir?
 * What hydraulic power would the system require to deliver water on top of Table Mountain from sea level for the pump selected?
 * What size electric motor would be required?

=Peer review= Name of peer reviewer: james Comments: a good authentic assessment, a nice detailed problem with many possible answers. for the criterion grid you need to give lot of detail, for each of the sections (document and oral). In the doc you already have the headings of application, structure and explanation. Now what would an excellently structured doc look like? what would typically be a poorly structured one that is not good enough (this you would know from marking students already)? Now what would count as a middling structure. These would form your structural criteria. Now do the same for application and explanation.

furthermore when i look at your outcomes (e.g. research) i do not see them i n the criterion grid? the outcomes must appear in the criteria and i n the guidance you give to students. Then there are the problems to consider. what are students supposed to do with these? How different are these from outcomes? I find it quite confusing to have points, criteria and outcomes as i am trying to think of all three at the same time and am getting confused! rather have three or so outcomes and expalin to me the reader how these fit with the task. What teaching was done to prepare students for the task? Where is the constructive alignment? =Changes implemented after peer review=
