Experiments

    General Instructions: You are required to conduct a total of nine experiments. One experiment will be performed each week, with the first experiment starting the third week of classes. Generally, there is ample time for you to complete the experiments within a lab period, provided that you read the lab manual before class. This point can not be overemphasized, you MUST be prepared for your experiments before coming to the lab. In many cases you may have to go back to your heat transfer and/or fluid mechanics textbooks to review the principles dealt with in the experiment. Don't be afraid to do so. Once again, you MUST read the lab manual and any background material needed before you come to the lab.

    In addition to the nine experiments, demonstration experiments will also be performed by the instructor and the teaching assistants, in the last few weeks of the semester, after the nine required experiments have been completed. The number and content of the demonstrations will depend on the availability of equipment and time. These will be scheduled later in the semester.

    The class will be divided into groups of four (or three/or five depending on the class size) where each group will perform one experiment/week. In the first week of the semester you will pick the people you want to work with and form a group. Once the members of a group have been picked they will work together the entire semester. The nine experiments are divided into three sets of three experiments. During a lab period all three experiments in a set are conducted simultaneously by three different groups so that all three experiments in a set are completed by all groups in three weeks. The experiments are then rotated to the second set for the next three weeks and so on. Each group will sign up for the experiments on the Sign up sheets posted on the door of Room 109. Details of the group arrangement will be further discussed in class.

Laboratory Reports:
Each student is required to write a laboratory report for eight of the nine experiments. For experiment number 4 (determination of aerodynamic forces), results will be presented in an oral presentation in class. The following table describes the type of report required for each experiment. Some guidelines for writing laboratory reports are included in the back of the lab manual, additional guidelines and a sample report will be provided second or third week of classes.

For the second experiment (not experiment # 2) performed by a group: Short report with Introduction and Experimental methods section.
For the third experiment (not experiment # 3) performed by a group: Long Report.

Laboratory reports will be due two weeks after the scheduled experiment. This is ample time for you to write the lab reports, provided you do not wait until the last minute. This DEADLINE WILL BE STRICTLY ENFORCED. Reports should be submitted to the TA's during the scheduled lab session.
10% WILL BE DEDUCTED FOR EACH DAY THE LAB REPORT IS LATE UP TO A MAXIMUM OF FIVE DAYS. NO CREDIT WILL BE GIVEN FOR REPORTS SUBMITTED LATER THAN THIS.

Laboratory Rules & Regulations :

    1.Absolutely no smoking, eating or drinking allowed in the lab. If you need to eat or drink, do it outside the lab.
    2. Put safety first and do not take any chances. The lab contains expensive and potentially dangerous equipment (if not handled properly). So, ask the teaching assistant if you are unsure about anything.
    3. NEVER try to FORCE anything e.g. if something such as a valve appears to be stuck do not use excessive force, please consult the lab instructor.
    4. The easiest way to be safe is to use your common sense.

Quizzes:
To encourage you to be prepared and to read the lab manual before coming to the laboratory, unannounced quizzes may be given at the beginning of a lab period. The quizzes will be simple and will only deal with the experiment you will be performing that day.

Test:
There will be one in-class test administered during the second last or last week of classes. The date will be announced in class later in the semester.

Final Project:
Each group is required to do a final project. The intent of the project is to give you a flavor of what conducting research is all about. As a group you must first decide the subject of your project and briefly describe the important aspects of this study in a short (1or 2 pages) proposal. Although brief, the proposal should include the following: a short background of the general area you will investigate, the relevance of the project , your method of approach and what you hope to learn from it. Of course, the final project must be related to the scope of this class. The proposals must be submitted by Jan. 27. Further details will be discussed in class.

Class Conduct :
At the beginning of the semester each student will start out with 5% for conduct/participation. You will lose points for disruptive behavior such as walking in and out of lecture, being chronically late, reading the newspaper during lecture, etc.

Grading Policy:

Class Conduct 4%
Reports

Short (5x6%) 30%
Intermediate (1 x 8%) 8%
Formal/long (3 x 11%) 33%
Final Project 15%
Test 10%
