Question

1.Student has provided general flow and data required for this work. 2.course is more related to Pharmaceutical so please do the necessary and not make it too much like a chemical

engineering based to provide- 1.just researching all the required resources for the report 2.want all the resources, data and references to write and do calculations in the report 3.some data is given, others either need to be found or use experimental data from other sources/n Assignment 2-MECH3002 Thermal resistances - Conduction and Convection – Thermal Mug Manufacturing This assessment will be marked out of 10 using the Rubric attached. The assessment is worth 10 % of the total unit mark. This assessment is to be completed in groups of 1-3 individuals. 1. Learning Outcomes: ● Apply theory learned in the lectures in practice Problem solving using engineering skill and analytical thinking Understand the correlation between convection and conduction Determine the importance of convection and conduction for specific projects ● 2. Background: We have studied the mechanism of conduction and convection. We also learned that there is a resistance associated with the traveling of heat in solids (conductive resistance) and in fluids (convective resistance). With this knowledge, it is possible to predict the heat loss in different bodies with different geometries. Particularly, we have studied regular shaped bodies such as walls, cylinders and spheres. Following the design of a thermos in Assignment 1 completed in Week 4, you are to use this knowledge and, as engineers, actually manufacture a thermal cup/mug in Assignment 2, Thermal cup/mugs (also known as travel mugs) are used to keep a beverage warm for a given period by making use of insulating materials and high-performance design. Patents for thermal cups date as far back as 1958. A relatively recent thermal cup patent issued in 2004 defines its invention as: "A thermal cup includes a hollow inner cup body having an inner surrounding wall and an outer surrounding wall that confine an enclosed chamber therebetween, and an outer cup body made of a heat insulating material and disposed to surround the outer surrounding wall of the inner cup body. The inner surrounding wall further confines a space for containing liquid therein. The outer cup body cooperates with the outer surrounding wall of the inner cup body to confine a clearance therebetween. A thermal conductor unit is provided on the outer surrounding wall of the inner cup body, and is disposed in the clearance." (Luo, 2004). 112 111 12 13- FIG. 1 PRIOR ART Figure 1: Patent sketch of a thermal cup from (Luo, 2004) 3. Your specific tasks are to: 1) Add the effect of convection to your previously submitted Assignment 1. Display (or estimate) all the heat transfer coefficients (conductive k and convective h) involved. Calculate the expected heat transfer and the expected energy loss over a 3-h period. 2) Determine the significance of convection in your design and then determine whether your original project will have any alterations before manufacturing. 3) Manufacture the cup/mug you have designed. You are actually going to manufacture (create, build, construct) the product you have designed. You are not allowed to buy a product ready off the shelf and present it as yours. But you are welcome to use off the shelf components or pieces that you may need. The requirements are: a. Total volume (dimension) cannot exceed 1.5 L b. Should hold at least 300 mL of liquid C. Cannot weigh more than 700 g d. Should be "liquid proof", i.e., cannot leak or deteriorate when in contact with liquids. e. Should keep contents at a temperature higher or equal to 55 % of the original temperature for 3 hours. f. Aesthetics will not be marked 4) Record the making of your cup/mug. You are to make a short video (2 min to 5 min) of you making your product. Edits are welcome. You don't have to record every detail, but the overall making of the product. Not all group members need to appear in the video. 4. Deliverables There are three straight forward deliverables for this activity: the project, the product and the video. They are described in more detail hereafter: A short 2-page document addressing all the tasks set in Section 3. It should have an executive summary (also known as an abstract in this case) that condenses to one paragraph what your product is and what it does (max 300 words). It should also contain the convection calculations, your decision on whether to modify the original product or not and what the modifications are (if any). This report should also contain the REFERENCES for everything you used that was created/published by others or previously. You can also reference your Assignment 1. The thermal cup/mug itself. The actual product that will be tested against the requirements given and against a professional cup/mug in the Macquarie workshop later in the semester. A 2 to 5 min long video showcasing your working on your thermal cup/mug. Video link should be in your project written report. 5. Assessment This assignment contributes towards the assessment of MECH3002. You will work for this project and hand in a report. The report will be marked out of 100. ■ Report due at 11:55 PM 29th October 2023. Unless a Special Consideration request has been submitted and approved, a 5% penalty (of the total possible mark) will be applied each day a written assessment is not submitted, up until the 7th day (including weekends). After the 7th day, a grade of '0' will be awarded even if the assessment is submitted. Must reference sources of information and include a complete reference list. The report must be well written, concise and clear. Document must address all aspects outlined in Section 3 Your specific tasks. 6. Rubric Assessed Marks capability (Total 100) Project Product Video 10 10 10 25 25 20 Competencies to be demonstrated for High Distinction Updated calculations for heat loss and energy loss are presented. The estimation for the cup/mug performance still meets the requirement set for the product. Discussion of whether project should be modified or not in light of the convection now being accounted. Delivering a product Product meets geometry, weight and holding content requirements Your product meets the performance requirement Your video is within the time limit, shows at least one member of the group working on your product, shows the final product (result) and is uploaded into a free video hosting website by the assignments due date. 7. Resources You can be creative about your project. Here are some videos to give you some inspiration on how to start your assignment. https://www.youtube.com/watch?v=mPJoCRbnFIE https://www.youtube.com/watch?v=oL86W7GmPWk https://www.youtube.com/watch?v=BRsBwwwoC U https://youtu.be/PY5Kryq62SQ
