V. Evaluation:
A. Testing Procedures:  35% of grade
The student's progress will be evaluated by three exams and an additional comprehensive final exam . 
B. Laboratory Expectations:  25% of grade
The laboratory work will comprise 25% of the course grade and the grade will be based on the laboratory notebook.  Each student will keep a laboratory notebook and write up each experiment in the notebook. The notebook will be kept in a manner similar to an industrial notebook for patent purposes. 
Laboratory experiments may vary depending on equipment availability and maintenance.  All experiments will require some student assembly of equipment. 
1 
 
 
 		 Heat transfer 
Experiments in convective heat transfer will be conducted using heat exchange equipment to compare theory and experiment. Using brass shell and tube heat exchanger, Pyrex shell and tube heat exchanger and air cooled heat exchanger.
2 
 
 
 		 Distillation 
Experiments in distillation of mixtures will be performed to compare theoretical calculations and experimental results. Using a Pyrex 3" Oldershaw column. A gas chromatography and/or FAIR will be used for sample analysis.
3 
 
 		 Absorption 
Experiments in absorption of carbon dioxide will be performed using a 6" glass column. A gas chromatography will be used for analysis of samples.
4 
 
 		 Filtration 
Filtration experiments will be performed using pilot scale  mixing and filtration equipment
5 
 
 		 Crushing and screening 
Crushing experiments will be performed using laboratory scale crushing and screening equipment.
 
C. Field Work: 45% of grade
Outside readings and library research will be required in this course. A formal written report will count 35% of the grade. Students will make a short oral presentation on their assigned heat exchanger and this will count as an exam. Homework assignments are an important part of this course and all homework assignments completed and submitted will be graded "A" and will comprise up to 10% of the course grade (as calculated below). 
D. Other Evaluation Methods:
N/A
E. Grading Scale:
The course numerical grade will be calculated using the formula below: 
G = 10 * H/HM + (.35 * (T(1) + T(2) + ... T(N))/N + .3 * F + .25 * L) / (.9 + .1 H/HM) 
where 
G  = the numerical grade 
H  = the homework grade 
HM = the maximum homework grade attainable 
T( i )= the grade on exam number i (Research papers and the oral report are included in this category.) 
N  = number of exams and research papers and oral report (excluding the final exam) 
F  = the grade on the final exam 
L  = the laboratory grade. 

Letter grades will be awarded based on the following schedule: 
90 – 100     A 
87 – 89       B+ 
80 – 86       B 
77 – 79       C+ 
70 – 76       C 
60 – 70       D 
below 60    F
VI. Policies:
A. Attendance Policy:
Pellissippi State Technical Community College expects students to attend all scheduled instructional activities.  As a minimum, students in all courses must be present for at least 75 percent of their scheduled class and laboratory meetings in order to receive credit for the course (Pellissippi State Catalog).  Individual departments/programs/disciplines, with the approval of the vice president of Academic and Student Affairs, may have requirements that are more stringent. 
Chemical/Environmental Engineering Technology Program: 
Regular attendance in this course is required.  Students who miss the equivalent of 10% of either classroom hours or laboratory may, at the discretion of the instructor, have their course grade dropped by one letter.  Students who arrive late for a class after the roll as been called have the responsibility of seeing the instructor after class the change their status from A (absent) to T (tardy).
B. Academic Dishonesty:
In keeping with college-wide policies, the student is expected to adhere to the general rules and regulations relevant to academic and classroom misconduct as outline in the catalog.
