Fluid Mechanics I and Organic Chemistry
"Water Works Engineering", Qasim, Motley, and Zhu, Prentice Hall PTE, 2000

Upon completion of the course, civil engineering students will be able to assess water quality and solve environmental engineering analysis and design problems in the area of water treatment, including:

  • Raw Water Intake, Screening, and Aeration
  • Flow Measurement
  • Coagulation, Flocculation, and Precipitation
  • Sedimentation
  • Filtration
  • Color, Taste, and Odor Control
  • Disinfection and Fluoridation
  • Water Stability
  • Residual Processing and Disposal
  • Plant Siting and Layout
Learning Activities

Learning activities help students meet the course goals. The learning activities are preparation, listening and discussing, and practice.

  • By preparation, I mean reading technical information before class, primarily by reading assigned material. This activity provides students with three benefits. First, students arrive in class with some introduction to the material they are expected to learn. Second, assigned readings often cover course topics with greater breadth and depth than can be covered in class. Thus, student learn more. Finally, learning how to effectively read technical information takes practice, just like learning how to play a sport or musical instrument. Many of the students taking this class will spend their careers creating and/or reading technical information. By "struggling" through difficult readings in college, students are better prepared for work.
  • You will listen to some lecture, as this is an effective way to transmit information; however, you are also expected to discuss material with the instructor and fellow students in class.
  • Finally, you will practice. This will be done in two ways: working examples in class and for homework and conducting laboratory exercises.
Evaluation Activities

The evaluation activities used in this class are linked to the learning activities.

  • Quizzes: Quizzes are used to evaluate your preparation for class. They occur before topics are covered in class and are based on knowledge gained from assigned readings. My goal is for students to carefully read assigned material. Students should not skim over or spend inordinate time on the readings. To help students, I provide a list of questions for each quiz. Each quiz list identifies concepts, pictures, figures, and tables in the readings that I particularly want you to understand. IMPORTANT: When I design quizzes, I assume that each student has carefully read the assigned material once, then used the study guide to identify important items for further study. Quizzes are given twice: once to individuals, then to small groups of students. This helps students learn all of the topics covered on a given quiz and provides an opportunity for discussion. When taking a group quiz, make sure that each student in your group understands the questions and answers.
  • Assigned Problems: Assigned problems are used to evaluate all of the learning activities. Specifically, they help me evaluate your ability to define and solve problems. Your work must be your own; however, I encourage students to compare answers. If you discover different answers, study each others work, then rework and discuss the problem until you agree on an answer (or agree to disagree). However, DO NOT COPY!. Use the Policy tab at the top of this page to review my homework policies. Please email, phone or stop by my office if--upon reviewing the text book and class materials and discussing a problem with other students in the class--you are unable to complete a problem.
  • Exams: Two semester exams and a final will be used to test your ability to independently solve problems. These exams will be closed book and notes. An equation sheet will be provided about a week before each exam. You can write additional equations and solution methods on this sheet and bring it to the exam.
  • Laboratory Assignments: Use the Lab tab at the top of this page to view material on the laboratory.
Grades in the course will be based on the ten point scale (90-100 = A, 80-89 = B, etc.). Depending upon class performance, the scale may be adjusted down, e.g., an 89 might be an A. This will be done at the end of the semester. Points will be awarded according to the following percentages: It is possible to change the distribution, with agreement of all students in the class and myself.
Quizzes 10 %
Assigned Problems 15 %
Laboratory 15 %
Semester Exams 40 %
Comprehensive Final Exam 20 %
Any student in this course who has a disability that may prevent him or her from fully demonstrating his or her abilities should contact me personally as soon as possible so that we can discuss accommodations necessary to ensure full participation and facilitate your educational opportunity.
Academic Misconduct
You are encouraged to work together on assignments. However, copying is not acceptable. Copied assignments will receive a zero grade. Cheating on a test will cause the student to receive a zero grade, at a minimum. If you are to miss an assignment due date, exam, quiz, field trip, or laboratory session you must have a valid excuse and notify me prior to the event (except in case of emergency).
