CE 135: Hydraulics Laboratory (Fall 2005)
Class time and place: Tuesday 1:30 - 4:20 pm; Santa Clara 1224 Instructor: Dr. Johnston Office: Riverside 4034 / Modoc 1001 Phone: 278-7939 Email: [email protected] Home page: www.csus.edu/indiv/j/johnstonj Office Hours:
EDUCATIONAL GOALS: 1. To observe fluid phenomena in a laboratory setting 2. To learn about aspects of fluid mechanics of particular interest to civil engineers 3. To practice oral and written communication skills 4. To practice using spreadsheets for engineering computations 5. To practice planning experiments
PREREQUISITES (and assumed background): CE 101, Engr 132, WPE
TEXT AND MATERIALS:
There is no required text. Lecture notes will, however, be keyed to Roberson and Crowe, Engineering Fluid Mechanics (the Engr 132 text).
Other reference books include: King H.W. and E.F. Brater, Handbook of Hydraulics Rouse, H., Elementary Mechanics of Fluids Chow, V.T., Engineering Fluid Mechanics Daughtery, R., J. Franzini, and E.J. Finnemore, Fluid Mechanics with Engineering Applications
Spreadsheet and word processing software, and access to the Internet for downloading procedures and data files and receiving email will be needed. All of the necessary computational resources are available in the College's computer labs.
CONDUCT OF THE CLASS:
1. Class Activities -- The normal sequence of events for a single lab exercise will be a 3-meeting sequence (see attached schedule). The first meeting will include lecture and classroom exercises. Data collection will be done during the second meeting. During the third meeting, some members of the class will make an oral presentation on the experimental results. So that all of the lab exercises can be accomplished, multiple activities will occur during the same lab period. For instance, it will be common to discuss last week's lab during the same class meeting that the lecture for next week's lab is presented (see schedule for details).
2. Attendance – Attendance at lab is very important. You will be allowed one (1) unexcused absence during the semester. After that, every unexcused absence will result in a 5% deduction from your final computed class grade. This deduction is separate from the "class participation" part of the grade noted below and has no upper bound. Absences do not excuse you from written or oral assignments. Get notes and data from your classmates. Also note that leaving a lab early may be counted as an absence. Plan on spending the whole scheduled period in the lab.
1 3. Safety – The lab contains hard surfaces, sharp edges, and potentially slick floors. For your safety, during the sessions in which data are being collected, please observe the following rules: No open-toed shoes or shoes that will cause you to slip on a wet floor. Observe professional decorum at all times (no horseplay). Clean up spilled water immediately. Because the water does not meet drinking water standards, no eating or drinking in the main room of the lab. Food will be allowed in the classroom space only. The instructor has the right and obligation to ask you to leave whenever you are not acting in a safe manner or are not properly equipped (i.e. proper shoes).
4. Oral Presentations -- Each member of the class will have the opportunity to participate in a single oral presentation on experimental results and their interpretation (see attached schedule).
5. Lab Write-ups -- Lab write-ups are important opportunities to test your understanding of the material and to practice communication skills. Your work should be organized, legible, and sufficiently documented so that readers can easily and unambiguously understand it. Unprofessional papers will be returned ungraded. Most lab write-ups will be informal, problem-set-style. At least one will be a formal, typed report. The formal report will be submitted twice. The instructor will provide comments and a preliminary grade on your first submittal. In your re-submittal, your final grade will be raised. Depending on how well you addressed the instructor’s comments, your score could go up to halfway between the preliminary grade and the total possible points. Because your preliminary grade is the starting point, it is to your advantage to do as good a job as possible on the first submittal. If you do not resubmit the report, you will receive the initial grade or one half of the total possible points, whichever is lower.
6. Deadlines -- Late assignments will be accepted through one week after the assignment’s due date, and will be assessed a penalty of 25% of the assignment's credit. Assignments will not be accepted for credit after that. Please talk to the instructor if you have a problem meeting a deadline.
7. Cheating and Plagiarism -- Cheating and plagiarism are breaches of professional ethics (see the ASCE Code of Ethics, sections 3b, 5e, and 6a), and University rules. You are advised to check the University Policy Manual (see URLs below) if you are unclear about the definitions and potential penalties associated with these actions, including "zero" grades in the class or on individual assignments. Note that copying from previous semester labs is one form of plagiarism. Although you are encouraged to collaborate in assignments to learn from each other, there is a fine line between collaborating and copying. Collaborating involves two or more people working together, with all brains working, and resulting in individual write-ups. Copying involves fewer-than-all brains working and write- ups that are identical, implying that one is an original and the others are copies. If in doubt, talk to the instructor.

BASIS FOR GRADING:
Written reports 78% Oral presentation of experimental results 12% Participation in experimental work during the lab and class discussions 10%
Tentative basis for final grades: A (>85%), B (76-85), C (66-75), D (55-65), F (<55%).
DISCLAIMER: The instructor reserves the right to adjust the class schedule, scope, and/or activities to meet unforeseen circumstances. All adjustments will be announced in class.
