Abstract A team consisting of five members conducted an experiment using a pitot tube, wind tunnel, and a hand held protractor. The purpose of the experiment is to measure flow velocity and determine the sensitivity of a Pitot-static tube to flow misalignment. From the experiment it can be concluded that at greater angles the pitot-tube’s ability to measure pressure decreases. Experimental Data & Procedure Table 1 Angle (Degrees) Total Pressure (Inches of Water) Total Pressure (Psi) Static Pressure (Inches of Water) Static Pressure (Psi) -20 1.17 0.04212 -0.17 -0.00612 -15 1.22 0.04392 -0.1 -0.0036 -10 1.25 0.045 -0.08 -0.00288 -8 1.27 0.04572 -0.07 -0.00252 -6 1.3 0.0468 -0.05 -0.0018 -4 1.29 0.04644 -0.04 -0.00144 -2 1.36 0.04896 -0.03 -0.00108 0 1.34 0.04824 0 0 2 1.36 0.04896 -0.03 -0.00108 4 1.37 0.04932 -0.04 -0.00144 6 1.38 0.04968 -0.05 -0.0018 8 1.29 0.04644 -0.12 -0.00432 10 1.36 0.04896 -0.08 -0.00288 15 1.29 0.04644 -0.17 -0.00612 20 1.07 0.03852 -0.23 -0.00828 Table 2 Static Ring Pressure 60 MPH 1.45 Static Ring Pressure Total Pressure Static Pressure Dynamic pressure 30 MPH 0.8 0.78 -0.02 0.8 2
In order to obtain the results in tables 1 and 2 the team conducted the following procedure: 1. First the wind tunnel fan was turned on and set the speed to 60mph.
