Industrial Chemical Calculations
The good student strives not for easy answers, but for genuine understanding, persevering in the face of obstacles. The good student wishes not just to "get it done," but to "get it right"; not simply to "get ahead," but to "get the most out of it."

Objective
This course is intended to develop the student's ability to use an engineering approach to problem solving. This approach requires the accurate and concise application of the principles of math, chemistry and physics to analyze and solve engineering problems. A detailed list of learning objectives that indicate the competencies to be achieved by the students can be found on the greensheet.
Time Commitment: It is expected that each student will devote a minimum of 7 - 10 hours per week studying the assigned reading and doing the homework.
Cheating and Plagiarism will not be tolerated in this course. Cases of academic dishonesty will result in an F on the exam or quiz, administrative disciplinary sanctions, and may result in an F in this course. Please review the College of Engineering Academic Dishonesty code, as that will be followed in this course.
Exam dates:
Exam I Thursday, October 9th
Exam II Thursday, November 6th
Final Exam Monday December 15th, 1215-1430
Structure of this Course:
The principles of Industrial Chemical Calculations will be developed by lecture and study outside the class. Applications will also be discussed in lectures and developed with homework and in-class problems. Collaborative learning is an important portion of this course.
Reading Assignments
Students will prepare for each lecture by reading through the appropriate text material as described in the syllabus below listed in the text reference column, including the example problems contained in the text. Students should complete the reading assignment that can be downloaded from the course website. The goal of the reading assignments is to assist students in extracting the important concepts from the assigned reading. Credit for each reading assignment will be assigned according to the type of question. If student solutions appear to be copied or paraphrased from old reading assignment solutions, no credit will be given for that assignment. Problems requiring several calculation steps, such as recalculation of text example problems, are worth 5 points and a correct answer must be obtained for credit. Other questions are worth 1 or 2 points, depending on the complexity of the question, and credit is given if the question is attempted regardless of how correct the answer is. Nonsense answers are not worth credit. Distribution of credit is at the discretion of the instructor.
BioEMB
The National Academy of Engineering has urged faculty to incorporate interdisciplinary projects and assignments into the undergraduate engineering curriculum. Thus, problems addressing biological applications will be part of this course. Students should register at the website: http://www.bioemb.net as a student so that assigned problems may be downloaded. The goals of this include broadening the applications from petroleum and traditional chemical processing to include bioprocessing, and are also to help students who may follow a career track in biochemical engineering.
Quizzes
Quizzes will be given periodically at the start of class. Quizzes will contribute to the course grade only in a positive degree - for each quiz on which you complete 85% correct, you will will be accounted one reading assignment credit. Quizzes cannot be made up or taken late. Arriving to class will forfeit the quiz. Quiz problems will be closed book/closed notebook and will be based on material covered in the lecture and in the text, especially on the example problems from the assigned reading.
Examinations
There will be two midterms and one final exam for this course. Midterm exams will be given during the normally scheduled class period. Results of each midterm exam represent 25% of the grade for the course. There will be no makeup exams and students will receive zero (0) credit for any exam they fail to take unless the absence is excused. Requests for an excused absence from an examination must be submitted in writing to the professor prior to the next scheduled class meeting following the exam. (No absence requests will be accepted for quizzes.) The score for an excused exam will be equal to the average for the remaining midterm exam and the final. Results of the final exam will represent 30% of the grade for the course. The final exam is scheduled for Monday, Dec 15, 2008 1215-1430. The exam must be taken at that time unless permission is given to the student requesting an alternate date on or before November 14.
You can expect the problems on the exams to cover concepts from the lectures, homework, and in-class problems, however, they will be different from the problems assigned in homework or class group problems. Engineering is the application of technical knowledge, and you need to demonstrate your ability to apply your knowledge of science and engineering technology to practical problems. Grading of the examinations will be based on the assumption that the student completed all the assigned homework and clearly understood all the required basic assumptions and equations used in the homework and that the student attended all the lecture classes.
Class problems
There will be some problems to be solved in class in groups, to develop concepts and also applications. Class problems are very important in that they provide an opportunity in-class to learn how to solve problems. The class problems will not be as difficult as the homework problems because only a short time can be devoted to their solution, but rather, they serve to introduce students to problem solving strategies. Prior to the second class meeting, the students should fill out The Index of Learning Styles Questionnaire that can be found at http://www.engr.ncsu.edu/learningstyles/ilsweb.html.
After taking the questionnaire, please submit for the results. Read the four numberlines and record your numbers:
PLEASE e-mail the results (as described in the box to the right) to the instructor.
Based on these results and the questionnaire from the first day of class, the instructor will make student teams of 3 people each. Students will be asked to sit with the teams for the duration of the semester in order to work together on class group projects.
Homework problems
The problem sets that are assigned throughout the semester should be considered the most significant learning experience of the course. In-class problems and exam problems cannot be as time-consuming as the homework problems due to time constraints in the classroom. Homework problems, however, will introduce the student to real-life problems that might be encountered by chemical engineers in industry. Problem sets may demand 5-10 hours weekly of study time.
Students are to be prepared to submit solutions to the homework problems at the start of the class on Thursdays. Students are welcome to work together on homework problems, however the student's grade will depend on individual mastery of the material. All homework will be graded. Solutions to the homework will be posted on the web (http://www.engr.sjsu.edu/ckomives/courses.htm). The homework will receive 10% of the course grade.
The minimum credit for homework turned in on time will be 70% credit if all the problems are solved to the requested value stated in the problem, even if the final answers are incorrect. Some problems can only be solved by trial and error and require the use of a computer. Problems requiring a plot must be done with a computer to receive credit. When using a computer to solve a homework problem, a printout of the computer spreadsheet should accompany the homework problem and a written explanation of the equations in the spreadsheet should be included to get credit for the solution. Solving the homework problems is essential to your successfully mastering the material in this course. Students who turn in all their homework are more likely to do well on the examinations than those who do not attempt the homework.
Student Feedback: Feedback is welcome and encouraged. To facilitate anonymous input from students, three volunteers from the class will be selected from the class to relay messages from the class to the professor. This way, the instructor will receive only the comments and not the name or e-mail of the person who sent it.
