CIVL 321 LABORATORY Spring 2024 Laboratory Group Report Format Organization of Report: I. Title page (see sample) II. Laboratory description handout III. Results table IV. Graphs* V. Answers to questions* VI. Appendix a. Raw data sheet b. Complete set of sample calculations * as requested in handout General Instructions: 1) Report must be complete, neat, and legible. 2) All pages must be 81/2" x 11", and bound/stapled together in the correct order. The name of the person who prepared each page (except the Title page) must appear in the lower right corner. 3) All report content must be typed, with the exceptions of: 1) The sample calculations. These can be handwritten. 2) The raw data information may also be handwritten on the data sheet. 4) Results tables must be prepared in a spreadsheet program or equivalent with appropriate headings. The dimensional units for all displayed results must be clearly indicated. 5) The sample calculations must take one set of data and show each calculation required to generate the Results table, produce the graphs, and answer the questions (if applicable). All unit conversions must be shown and all calculations must carry at least three (3) significant digits. Sample calculations may be handwritten in pen or pencil – but they must be extremely neat. 6) Graphs must be prepared in a graphing program such as Excel or Matlab and follow accepted engineering practice as indicated below and shown in the example on the following page: a. b. C. d. e. f. g. Each graph must contain a meaningful title that describes its content. Coordinate axes must be appropriately scaled and have major gridlines. Coordinate axes must be labeled with words, symbols (if applicable), and proper units. Experimental data should appear as marker symbols without lines. If requested, x- and y- error bars should be indicated on each data point. Theoretical curves should appear as smooth lines without marker symbols. They should be clearly labeled to indicate they are theoretical results. Least-square curve fits (Trendlines) must be accompanied by the curve fit equation and R² value with at least three (3) significant digits shown. Multiple data sets on the same graph should be clearly identified through the use of labeling or a legend. Grading: The laboratory experiments reports are expected to be neat, succinct, and well written. Unless otherwise stated, all reports must be submitted at the beginning of the laboratory period following the performance of the experiment. Late reports will not be accepted. All students who contribute to the experiment and report will receive the same grade. Sample Title page Specify lab by group number, day, and time. Names listed in alphabetical order by last name Drag Coefficient Measurement of an Ogive-shaped Projectile in Subsonic Flow CIVL 321 Laboratory Spring 2024 California State University, Chico Lab Group #1, Thursday 2 pm Daniel Bernoulli Leonhard Euler William Froude Osborne Reynolds January 25, 2024 Drawdown (m) Sample Graphs & Tables Graphs have meaningful title, axis labels with proper units. Note that the titles tell me more than just "Drawdown vs. time", which I should know already just by looking at the axis labels. Clear legend, data as markers, theoretical as line, and at least 3 significant digits in regression equations. Tables have clear headings for each column with the dimensional units clearly specified. Values are listed with appropriate number of significant digits. 2 Line fit to drawdown at 80 m from well using log transformed time (first 4 data points removed) 1.8 1.6 drawdown (m) 1.4 1.2 1 0.8 0.6 drawdown (obs) Linear (drawdown (obs)) y=0.5912x+ 0.0865 R² = 0.9988 0.4 0.2 0 0 1 2 3 log time (min) Drawdown at 80 m from pumping well Time (min) Drawdown (meters) 2 1.8 0.5 0.16 1.6 1 0.18 2 1.4 0.24 3 0.27 1.2 4 0.47 1 Drawdown (obs) 5 0.50 0.8 Theis solution 7 0.57 0.6 10 0.68 20 0.84 0.4 30 0.96 0.2 50 1.06 0 100 1.29 0 200 400 600 800 1000 1200 Time (min) 200 1.46 500 1.68 1000 1.86
