Unformatted text preview: ENGR-301 Assignment 3 Assignments must be submitted ONLINE on the course website (using Moodle) Due 23:59 Thursday (28-May-2015) Check the best answer (closest to the exact answer such that the absolute value |answer given – exact answer| is minimum) for each question. 3-1 Your company intends to purchase a 400 tonne capacity injection moulding machine. A similar machine was purchased eight years ago for $89,500. The price index for heavy duty equipment in the plastics industry was 163.6 eight years ago and is 207.6 now. Estimate the current cost of the machine. ($125,000 $113,000 $108,000 $98,000) 3-2 – 3-3 Nadia, John, Saba and Kumar are working together on a project. These are the data for each: Nadia: 60 hours, overhead rate 75%, personal time 10%, $20/hr John: 80 hours, overhead rate 55%, personal time 12%, $40/hr Saba: 80 hours, overhead rate 75%, personal time 10%, $36/hr Kumar: 40 hours, overhead rate 55%, personal time 12%, $20/hr 3-2 Who has the highest direct labour costs? 3-3 Calculate the total direct labour costs (Nadia John Saba Kumar) ($14,800 $14,000 $15,100 $14,300) 3-4 – 3-6 Weldex Industries begins to manufacture a newly designed, small, spot welding machine. The labour hours required for making the second and third units are 28.6 and 28.2 hours respectively. 3-4 Calculate the labour hours required to manufacture the first unit. (28.8 29.1 29.3 29.5) 3-5 Calculate the labour hours required to manufacture the 50th unit. (29.3 27.9 25.5 23.8) 3-6 If labour costs are $18/hour, calculate the total labour costs to produce the first four machines ($1900 $1950 $2000 $2050) 3-7 – 3-10 A 50-mgpd (million gallons per day) water treatment plant was proposed in 2013 for Ureka. A 60mgpd plant using the same treatment process was built in 2007 in Vancouver for $50,000,000. Given the following additional information and assumptions: • • • • • • Poor site condition in Vancouver required an additional $3,000,000 for foundations, which is not anticipated for Ureka. Assume the power sizing size exponent = 0.67. Assume inflation will persist at an average 4% per annum. Assume the location index for Vancouver is 1.17 and 1.24 for Ureka. A new high-pressure filter process will be added at Ureka at an additional cost of $4,000,000. The construction period for the new plant will include winter construction. The Vancouver plant was not constructed through a winter season. Assume an increase in construction costs for Ureka of 12%. In order to make an order of magnitude estimate of the water treatment plant in Ureka, various multiplication factors need to be calculated. 3-7 Calculate the multiplication factor based on the different capacities (0.80 0.90 1.00 1.10) 3-8 Calculate the multiplication factor based on effect of inflation (1.37 1.22 1.42 1.27) 3-9 Calculate the multiplication factor based on the different location indexes (1.07 1.03 0.99 0.95) 3-10 Calculate the order of magnitude estimate of the water treatment in Ureka (35M 50M 65M 85M) ...

Researching and applying science and technology in societal context; integrating and synthesizing knowledge; communicating information and knowledge via oral, written, and visual presentation.

 

Prerequisites: ENG 102 and PHYS 181 with a "C" or better; CH 201 or 202; CH 203; junior or senior standing

 

Satisfies:  Core Capstone; CO9 (Science, Technology, & Society); CO13 (Integration & Synthesis); ABET Criteria a, b, d, f, g, h, i, and j.

 

Student Learning Objectives

Core Objective 9 (Science, Technology, & Society):  Students will be able to connect science and technology to real-world problems by explaining how science relates to problems of societal concern; be able to distinguish between sound and unsound interpretations of scientific information; employ cogent reasoning methods in their own examinations of problems and issues; and understand the applications of science and technology in societal context.

 

  1. Students will be able to apply knowledge of mathematics, science, and engineering. [integrates CO2; CO3]
    1. Students will explain how science relates to a problem of societal concern.
  2. Students will be able to design and conduct experiments as well as to interpret data. [integrates CO2; CO3]
    1. Students will distinguish between sound and unsound interpretations of scientific information.
  3. Students will have a knowledge of contemporary issues. [integrates CO11]
    1. Students will identify the societal impacts of contemporary issues (such as sustainability, energy problems, water quality, and information science).
  4. Students will have the broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and societal context. [integrates CO11]
    1. Students will employ cogent reasoning methods in their own examinations of problems and issues.
    2. Students will describe how scientific and technological developments affect society and the environment.
