Question 3 a) Using annotated diagrams, explain the workings of a Vapour Compression Refrigeration System. You should include details of the changes of the state of the refrigerant as it goes through the refrigeration cycle. [13 marks] (Word limit: 300 words) b) Refrigeration can also be achieved with a Vapour-Absorption System. Using diagrams where appropriate, explain the main principles of this system and the advantages and disadvantages of this compared to a Vapour Compression system. [12 marks] (Word limit: 250 words)
E-PORTFOLIO BRIEF Create a Mahara e-portfolio based on the template Revit and Sketching E-Portfolio. Orthographic 6 Introduction Orthographic projections are used to represent 3D components on a flat surface in a 2D form. The two main types are First Angle Projection and Third Angle Projection (TAP). We will focus on TAP. Perspective Introduction Perspective drawings represent most faithfully the way spatial configurations look in real life. They communicate overhead or suspended forms particularly well, and sections through structures that need to be seen spatially within an enclosure. Perspective grids can be con- structed simply and be drawn over again and again on tracing paper at any scale in presentation drawings or quick sketches. Isometric Introduction Isometric drawing is one of the most popular engineering drawing methods because it lets you see the top, front and side of what you are drawing. Its distortion is gentle, unlike perspec- tive, and it gives you a crisp model of what you have in your minds eye. Oblique Introduction In an elevation oblique drawing the frontal plane is an orthographic elevation and the side planes are drawn at 30° 45° or 60°. If a measured drawing is being constructed with 30° side planes, it's lengths are not fore- shortened. If 45° or 60° side planes are used, all lengths are halved to minimise the optical distortion.
The break-even point can be defined as the production and sales levels of a given product at which the revenue generated from the sales is perfectly equal to the production cost. At this point, the company does not make any profit or loss; that is, it breaks even. The shut-down point refers to the minimum price where companies prefer shutting down their operation instead of continuing to operate. In other words, it is the minimum price and quantity for keeping operations open. Break-even price P2 Shut-down price P1 MC £ AVC 9? 9? ATC As seen previously, the break-even point is the point where the marginal cost (MC) equals the average total cost (ATC). The shut-down point of production, on the other hand, is the price at which the marginal cost does not even cover the average variable cost (ATC). At this point, the company is better off stopping its production than keeping producing at a loss. Suppose the hospital operates in a perfectly competitive market. The market price of this product is $40. Assume that a manufacturing company Total Cost (TC) function is TC = 20Q6Q+Q" What is the minimum market price for which you will choose to produce?

Problem 1. Draw a Context diagram and a Data Flow Diagram for a manufacturing company with a material handling and financial system that works as follows: Widget Corporation makes high-tech fly swatters. The units include a mm-Wave RADAR system that makes a final tweak in the arc of the swing to ensure a successful "end-game". The supply chain follows a classical SIPOC approach: Raw materials arrive from the vendor and are inspected. The materials enter production, products are fabricated, tested, moved to a short- term warehouse, then shipped to distributors. Vendors are paid after incoming inspection verifies the raw materials and Distributors are invoiced after finance is notified that the products are shipped. Distributors have 30-days to pay for their products after invoicing.
Pls read and summarize Chapter 2-3 from your book. Quality Management for Org. Excellence. • You will read the chapters and make a summary of 2 pages for each chapter.if you include a schema or table it may exceed 2 pages, but do not include all • You will put your comments and Ideas about the topic as my opinions title • It is what you understand • Scores are given for how much you understand and how neat the summary is prepared (the summary needs to be done after reading the whole chapter, not as part by part) Dont forget hat I told you abot the summaries to receive a high score. (Do you agree or not agree which part and why.) Don't copy paste!

Question 1 ? You are required to upload your solutions and working out as either a Word, PDF or JPEG file. A South Australian Industrial Centre has four machines of five different types and operates 40 hours per week. Part-mix ratios, batch quantities, part routings, machines, servers, and production times are given in the table below for the five-part styles produced in the shop.
