PREREQUISITES: Elementary Mechanics of Fluids, CE 319F, or equivalent. COURSE AIMS AND OUTCOMES: By the end of this course the students will be able to: 1. Identify and define fundamental concepts in hydraulics 2. Use graphs in analyzing fluid system performance and characteristics 3. Sketch primary characteristics of different fluid flows 4. Analyze data from laboratory experiments and quantify uncertainty in experimental results GENERAL TOPICS TO BE COVERED: 1. Flow in pipes and pipe networks 2. Pumps 3. Open channel flow 1
CLASS POLICIES AND PROCEDURES: 1. Class attendance is strongly encouraged. 2. Lab attendance is mandatory and lab schedule is listed below. 3. Homework and Lab Reports will be submitted only on or prior to their due date, and late work will not be accepted unless I am notified (via email linasela@utexas.edu) a full 24- hrs prior to the due date. If the notification email is timestamped prior to 24-hrs before the due date, an extension is automatically granted, and the assignment (homework or lab report) is to be submitted at or prior-to the next course lecture, without penalty. Each student will be granted only 3 extensions per semester, and only 1 extension per assignment. If the notification email is timestamped after the 24-hr period prior to the due date, the assignment may still be submitted for my review, yet will not be graded; you will receive a 0 grade for the assignment. 4. All exams for this course will be conducted without use of the textbook or class notes. For each exam, you will be permitted HAND-WRITTEN (non-copied or typed) notes on a single (1) 8.5 x 11 piece of paper. Notes not meeting these descriptions will be confiscated during the exams. 5. Exams will require the use of a calculator. No usage of computers, tablets, smartphones, etc. will be permitted during exams. LABORATORY: Students are required to sign up for a laboratory session. Attendance at laboratory sessions is mandatory and laboratory sessions will be graded based on attendance, participation and lab reports. Make-up labs will not be conducted. If students are unable to attend their scheduled lab session they may check with the TA ahead of time to see if it is possible to attend a different session. Note that such permission may not be granted if it would overload one of the lab sessions. You will not get credit for attending a lab outside your normal session without prior approval from the TA. Only hardcopy submissions of lab reports will be accepted electronic documents (email, pdf, etc) will not be accepted or graded. HOMEWORK: Homework will be assigned, graded and returned. Homework will be assigned on Tuesdays and are due at the beginning of class on the following Tuesdays. Only hardcopy submissions will be accepted electronic documents (email, pdf, etc) will not be accepted or graded. EXAMS: There will be two mid-term exams during the semester and a final exam. All the exams are closed book, closed notes. Midterm exams will cover part of the class material and the subjects will be announced in class. The final exam will be cumulative. Exams will include problems and theoretical questions. Missed examinations may be made up only if the reason on missing was illness or other emergency. The make-up exam will be an oral exam. 2

Robert J. Houghtalen, A. Osman Akan, and Ned H.C. Hwang, ISBN: 0136016383. Required. Basic fluid mechanics textbook such as the one used in CE 319F Recommended. COURSE/INSTRUCTOR EVALUATIONS: An evaluation of the course and instructor will be conducted at the end of the semester using the approved UT Course/Instructor evaluation forms. In addition, I will request feedback from students throughout the semester. UNIVERSITY POLICIES: Scholastic Dishonesty: Students who violate University rules on scholastic dishonesty are subject to disciplinary penalties, including the possibility of failure in the course and dismissal from the University. Since dishonesty harms the individual, all students, and the integrity of the University, policies on scholastic dishonesty will be strictly enforced.

Privacy-Web Based Class Sites: Web-based, password-protected class sites may be associated with all academic courses taught at the University. Syllabi, handouts, assignments and other resources are types of information that may be available within these sites. Site activities could include exchanging emails, engaging in class discussions and chats, and exchanging files. In addition, electronic class rosters will be a component of the sites. Students who do not want their names included in these electronic class rosters must restrict their directory information in the Office of the Registrar, Main Building, Room 1. For information on restricting directory information, see http://registrar.utexas.edu/catalogs. Drop policy: From the 1st through the 12th class day, an undergraduate student can drop a course via the web and receive a refund, if eligible. From the 13th through the university s academic drop deadline, a student may Q drop a course with approval from the Dean, and departmental advisor. Religious holydays: By UT Austin policy, the student must notify the instructor of his/her pending absence at least fourteen days prior to the date of observance of a religious holy day. If the student must miss a class, an examination, a work assignment, or a project in order to observe a religious holy day, he/she will be given an opportunity to complete the missed work within a reasonable time after the absence.
