show clear solution thank you An overhead 25-m-long, uninsulated industrial steampipe of 100 mm diameter is routed through a buildingwhose walls and air are at 25°C. Pressurized steammaintains a pipe surface temperature of 150°C, and thecoefficient associated with natural convection is h = 10W/m? • K. The surface emissivity is e = 0.8.(a) What is the rate of heat loss from the steam Jine?(b) If the steam is generated in a gas-fired boiler oper-ating at an efficiency of ny = 0.90 and natural gas ispriced at C, = $0.01 per MJ, what is the annualcost of heat loss from the line?%3D

Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position! Good luck interns, Ms. Frances…

Questions Three Consider the office chair design below, develop the design matrix and identify its type. Answer
Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…
