Conclusion:

In general the models agreed well, except for a single data point. This error was relatively small, only being 8.5% of the entire data range. This error was most likely caused by a single measurement error. The error value is greater than the theoretical value, which suggests that the temperature might have been read at a "hot spot". In the procedure the temperature measuring location was not fixed, which probably resulted in a variation in measurement location.

3.3.1.2 - An Example Final Draft of a Report

• A final draft of the report is available on the course website in Mathcad format, and it will be distributed in the lab.

3.3.2 Research

•Purpose: After looking at a technical field we use these reports to condense the important details and differences. After reading a research report another reader should be able to discuss advanced topics in general terms.

•Strategy A:

1.Clearly define the objectives for the report

2.Outline what you know on a word processor in point form and find the ‘holes’

3.Do research to find the missing information

4.Incorporate the new and old information (still in point form)

5.Rearrange the points into a logical structure

6.Convert point form into full text

7.Proof read and edit

3.3.3 Project

• Purpose: These reports allow the developer or team to document all of the design decisions

page 94

made during the course of the project. This report should also mention avenues not taken. Quite often the projects that we start will be handed off to others after a period of time. In many cases they will not have the opportunity to talk to us, or we may not have the time. These reports serve as a well known, central document that gathers all relevant information.

•Strategy A:

1.Define the goals for the project clearly in point form

2.Examine available options and also add these in point form

3.Start to examine engineering aspects of the options

4.Make engineering decisions, and add point form to the document

5.As work continues on the project add notes and figures

6.When the project is complete, convert the point form to full text.

7.Proof read and edit

3.3.4 Executive

• Purpose: These reports condense long topics into a very brief document, typically less than one page in length. Basically these save a manager from having to read a complete report to find the details that interest him/her.

3.3.5 Consulting

• Purpose: These reports are typically commissioned by an independent third party to review a difficult problem. The consultant will review the details of the problem, do tests as required, and summarize the results. The report typically ends with conclusions, suggestions or recommendations.

3.3.6 Interim

• Purpose: This report is normally a formal report to track the progress of a project. When a project is initially planned, it will be given a timeline to follow. The interim report will indicate progress relative to the initial timeline, as well as major achievements and problems.
