Goal: Introduce Civil Engineering students to concepts in thermodynamics, fluid dynamics, and heat transfer that will be used in their careers.

Textbook: Fundamentals of Thermal-Fluid Sciences, 4th Edition, Cengel, Cimbala, Turner, 2012

ISBN-13: 978-0077422400 ISBN-10: 0077422406

(Fundamentals of Thermal-Fluid Sciences (SI Units) 4th (fourth) Edition by Cengel, Yunus A., Cimbala, John M., Turner, Robert H. published by McGraw-Hill Higher Education (2012) Paperback) is also acceptable and much cheaper, but you will have to copy homework from the solutions listed on this website.

There is also a 5th edition out but I am using the 4th. Please notice that the homework problems are all copied onto the solutions supplied on this website.

Class organization: Class will be taught as a combination of lecture, demonstration, and problem solving.

Tests will be part conceptual, centered on the conceptual problems, reading, and presentations and part quantitative problems, centered on the assigned problems.

Quizzes will be over assigned homework. Homework problems will not be turned in directly but the quiz may be one of the homework problems. Quizzes will be at the beginning of period and will not be announced in advance.

Grades

Grading: homework 20%, quizzes 20%, 2 midterms 2*20%, final exam, 20%. Final exam will serve as makeup exam and will replace the score on any midterm/average of homework if final exam score is higher. This means the final is worth 20% of the grade if you do poorly on it and 40% of the grade if you do well on it. Homework due one week after assigned. Homework must be solved using your own work, not a direct copy of the answers. Note that all the answers are given. I strongly recommend covering the answers and only looking at them when your are stuck and/or to check your approach and final answer. Solving problems is the key to learning the material.

Tests will be closed book. Tests allow for use of the equations/parameter sheets and one page (1 side) of student notes "cheat sheet". The student notes can have any content as long as they are not copied from another student. The final exam will allow two pages of student notes (e.g., the ones from the midterms).

Policy on Cheating

Students are expected to be above reproach in all scholastic activities. Students who engage in scholastic dishonesty are subject to disciplinary penalties, including the possibility of failure in the course and dismissal from the university. "Scholastic dishonesty included but is not limited to cheating, plagiarism, collusion, the submission for credit of any work or materials that are attributable in whole or in part to another person, taking an examination for another person, any act designed to give unfair advantage to a student or the attempt to commit such acts." Regents' Rules and regulations, Part One, Chapter VI, Section 3, Subsection 3.2, Subdivision 3.22. Since, scholastic dishonesty harms the individual, all students, and the integrity of the university, policies on scholastic dishonesty will be strictly enforced. In short, cheating will not be tolerated.

Approved calculators for tests: NCEES has approved the following list of calculators for use in the April and October 2013 exam administrations:

Casio: All fx-115 models. Any Casio calculator must contain fx-115 in its model name. Examples of acceptable Casio fx-115 models include but are not limited to the following:

  • fx-115 MS
  • fx-115 MS Plus
  • fx-115 MS SR
  • fx-115 ES
  • fx-115 ES Plus

Hewlett Packard: The HP 33s and HP 35s models, but no others.
Texas Instruments: All TI-30X and TI-36X models. Any Texas Instruments calculator must contain either TI-30X or TI-36X in its model name. Examples of acceptable TI-30X and TI-36X models include but are not limited to the following:

  • TI-30Xa
  • TI-30Xa SOLAR
  • TI-30Xa SE
  • TI-30XS Multiview
  • TI-30X IIB
  • TI-30X IIS
  • TI-36X II
  • TI-36X SOLAR
  • TI-36X Pro

Class Format

The class will generally consist of short lectures followed by problem solving sessions. Some of the problem solving sessions are intended to promote thought and discussion; others are to work through homework. It is expected that the student will have read the relevant chapter and worked all assigned homework prior to coming to class.
