Question Description

Hello bro ,


How are you?


I need you please to do this lab for me. Its a waste water engineering lab report. you can start writing the lab till I get back with you later today with the calculation.

I want you please to do your BEST and stay away from plagiarism.

The reports required for the Civil Engineering Materials Courses should be neat, orderly, and produced individually, unless otherwise instructed. In general, all text should be 12-point font Times New Roman. Please single space the lines (or use 1.15 as done here) and put an extra space between paragraphs. All paragraphs should be “justified” (i.e. not left aligned). Tables and figures should be just large enough to read and should be properly referenced in the text. Captions should be placed below all figures and above all tables (ex: Table 1: description of Table 1). Remember that someone should be able to read your report and be able to understand what you did, how you did it, and the results of your testing/design calcs. All reports must be submitted in paper form. Reports The reports are designed to be somewhat longer than the memo reports and provide more information. The lead author is responsible for putting all of the parts of the report together, making sure the language is consistent, and submitting the report. They essentially act as the project manager for that lab. All team members are responsible for working on individual sections, data analysis, proof reading, etc. Each team will need to decide how to divide the work for each group report; however, a sheet with the percent of each task completed by each team member will be submitted with each report. The lead author is also responsible for attaching an evaluation rubric with the top portion completed. Appendix B includes an example of the format of the Group Memo Report and a copy of the grading sheet. A-1 Appendix B: Group Reports Format of Group Reports………………… B-2 Group Report Grading Sheet……………. B-5 B-1 Date John Demtry, Ph.D., P.E. University of South Alabama Department of Civil, Coastal, & Environmental Engineering Solorado, AL Subject: Design Lab Title Introduction and Objective 2 paragraphs: 1 for introduction 1 for purpose/objective (what, when, where, why) Engineering Team Members The team consisted of the following individuals… (put in alphabetical order) The primary author of the report is …, the secondary author of the report is … Description of the Design Lab Activity Give a brief verbal description of design lab activity. Be sure to include a description of the methods used, any standards/design criteria that were followed (10-State Standards, etc.), and any engineering judgement justifications used. This section should be technical, but “to the point”. Describe what was what were determined/calculated, and how. Results and Discussion The results section should include all of the determined/calculated results. Make sure you have good use of tables and graphs, if needed. You will also briefly discuss your results and each table/figure in this section. B-2 References The references should be listed alphabetically with no numbering. Appendices Each appendix should start on a new page. Appendix A. Design criteria, standards, codes used. Appendix B. Sample calculations and figures/tables of determinations/calculations. Appendix C. Report of contributions by each team member. B-3 Sample Format for Appendix C Design Lab Title Date of activity Your group number Task Introduction and objective Description of the experiment Results References Appendix A Appendix B Appendix C Name of Primary Author 60 40 50 Name of Secondary Author 40 60 50 10 50 50 50 90 50 50 50 Analysis tasks (list tasks below) B-4 CE 471: Water/Wastewater Design Lab Group Report Evaluation Primary Author: _______________________________________ Secondary Authors: _____________________________________ Group Number: ____ Design Lab Name: ____________________________________________________ The report will be evaluated for technical correctness, clarity of explanation, grammar, and spelling.
