Abstract A team consisting of five members conducted an experiment dealing with shear stress at the surface of air about an object using a wind tunnel and boundary layer mouse. The team saw good results when comparing Theoretical Velocity to Height (see figures 1-3), and not as good results looking at the Karman Plot in Dimensionless Form. Table 1 12 mph 16 mph 25 mph 0.018 0.09 -0.12 -0.08 0.025 0.08 -0.11 -0.03 0.030 0.06 -0.08 -0.05 0.040 0.04 -0.07 -0.01 0.060 0.03 -0.10 0.03 0.080 0.02 -0.05 -0.01 0.100 0.00 -0.08 0.04 0.120 0.05 -0.09 0.01 0.160 0.03 -0.07 0.05 0.200 0.04 -0.08 0.03 Static Ring 0.15 0.02 0.14 *Distance = 8.75 inches In order to obtain the results in table 1 the team conducted the following procedure: 1. The team first centered the boundary layer mouse directly in the center of the wind tunnel. 2. Next the team connected tubes to all the pressure sensing holes on the boundary layer mouse to the rotary dial on the wind tunnel. 3.
