Step 1.
Using the sliders to the left and below the probe gage, move the probe to a position
as close to the ball as possible and as close to the center (from left to right) as
possible. The probe position is the location of the small red ball in the view window.
Step 2.
Using a ruler, measure
the distance between the red ball of the probe and the center of the ball.
How fast is the airstream moving around the ball at this distance?
Distance ___________inch.
Speed of the airstream ______________mph.
Step 3.
By moving only the
slider to the left of the Probe Gage move the probe vertically above
and the ball and take five readings of distance and speed. Record these in the
chart below. Repeat this for five readings below the ball.

Step 4.
Using two different
colored pens, graph the information from the chart on the graph found in
the worksheet. Graph #1 will be the upper side of the ball, and graph #2
will be the lower side.
