A wall is constructed of two layers of 1 cm thick plaster board (k = 0.17 W/m.K) placed 12 cm apart. The space between these two is filled with fibre glass insulation (k = 0.035 W/m.K). Determine (a) thermal resistance of the wall (b) R value of insulation (c) heat transfer rate for temperature difference of 150°C.

Part 2 Set up a spreadsheet solution to this problem. This will require that you derive one formula to express the relationship between the friction coefficient, the spring constant, and the spring compression; and a second formula to find the cost of using different slide and spring types. Set up your spreadsheet as shown below. You can fill in the "Acceptable?" column manually, rather than using a formula. Turn in a copy of your spreadsheet/Matlab work (solve for $) Friction Spring Constant Spring Compression M k 0.1 0.1 0.1 0.2 0.2 0.2 50 100 150 50 100 150 4 Part 3 Your boss has decided to look at a second option. The spring mechanism will be replaced by a drop box. After leaving the slide, the blocks will travel 5 horizontal feet through the air and pass through a hole into the drop box. Using the slide you selected above, determine how far below the slide (h) to place the hole in the drop box. Yo = 5.2017/5 BLADE 2 RAMPE SLIDE 8⁰ SLIDE Acceptable? (Yes or No) $' Cost 51 In DROP…

As an engineer responsible for monitoring works in the area of ​​mechanical systems, you must evaluate the following situation: a large client in the retail area has a refrigeration system where it stores some chilled or frozen products to be sold on the sales floor.Recently, the customer's maintenance department has been questioning the system's performance and requested an evaluation of the system's behavior. You went to the location and requested some information from the maintenance manager about the system, who provided the following data: - The system operates with R-134a refrigerant;- The refrigerated environment is maintained at 0°C and the external environment at 26°C;- The refrigerant flow rate in the system is 0.08 kg/s; In addition to the data provided, you carried out some tests and measured the temperature of the refrigerant fluid at some specific points in the system, such as the compressor inlet and condenser outlet, finding values ​​of 0°C and 26°C respectively.…
