Process Synthesis
Spring 2000

1. Problems are to be presented on good-quality paper, 8 1/2 inches by 11 inches, ruled or unruled (e.g., white paper, engineering paper, etc.).

2. Include the following information at the top of the first page:
   1. Student's name.

   2. Date problem set is due.

   3. Instructor's name.

   4. Class section or meeting time.

3. Begin the solution of each problem after a small separation or on a fresh sheet of paper. Arrange the problems in numerical order, with each sheet numbered in the upper right hand corner. The sheet number and the total number of sheets in the set are to be shown. For example, 2/5 would mean the second sheet in an assembly of 5 sheets. The sheets must be stapled together in the upper left-hand corner

4. The work may be done in pencil or pen, but must be neat, legible, and organized. You may find it convenient to make your initial solution on scratch paper and then work up the final solution on fresh sheets of paper.

5. Work is to be done on one side of the paper only.

6. The solution must always be presented in such a manner that the correlation between the numerical setups and the formulas upon which the setups are based is immediately apparent.

7. Example: A first order chemical reaction occurs in a CSTR with rate constant equal to 10.0 hr^-1. If the flow rate to the system is 50.0 ft³ /min., find the volume of reactor necessary to obtain 60.0% conversion.
   • Acceptable solution:
     

   • Unacceptable solution:

     

8. In reporting your results, you should employ only as many significant figures as the available data merit.

9. In general, except for obvious cases, when equations are used which are not derived, a note should be made to the light of the equation stating the source (reference) from which the equation was obtained.
   • Example
     (Walas 5-8)

10. In some problems, such as numerical integrations, the same calculation will have to be repeated several times. In such instances the original formula will have to be put down only once, but the results of each calculation should be shown. In general, all calculations that are made should be presented in the homework in a neat and organized manner.

11. Although it is expected and encouraged that students discuss the problems with their colleagues, the actual solutions should be worked out individually. If there is strong evidence of collusion, the grade of each student involved will be divided by the total number of students working together.
