Methodology

We are interested in proving the existence of a constant breeze and finding out where it is coming from. Our methodology is as follows:

1. Using two anemometers we measure air speed (to show existence) and temperature (to isolate the cause).

2. We started out by defining specific locations to measure air speed and temperature within the Knight Library. We took the measurements in four locations on each floor with the exception of the first floor where we were only able to measure three locations. The locations of measurements are identified as A, B, C and D located on the floor plans.
A. Fifty feet north of the stairwell
B. Fifteen feet north of the stairwell
C. Fifty feet east of the stairwell
D. Fifteen feet south of the stairwell


3. We took two sets of measurements (utilizing two anemometers) about six feet apart of both temperature and air speed at each location as described above. Two of us held each anemometer such that the opening to the filament was pointed in the direction of airflow. Airflow is determined by holding three feet of toilet paper in the air, taking notice of direction.

4. Within the stairwell, two data sets were taken - one on the inside wall and another on the outside wall of the stairwell. view diagram

5. On the first and second flights of stairs, the measurements were taken at the bottom and middle of the stair. view diagram

6. At the doorway to the base of the stair between the third and fourth level, we took measurements at: view diagram
i. The outside entrance to the stair
ii. Directly inside the threshold
iii. One-quarter of the way up, one-half of the way up
iv. Three-quarters of the way up, and at the top of the stair.

7. Data will be captured to represent the regular operating hours for the Library. The range is defined by morning (7:30am - 12 noon), afternoon (1pm - 5pm), evening (5pm - 9pm) and closing (9pm - 12 midnight). Initally, data sets will be captured for morning and afternoon to evaluate and analyze for improvement.
