Differential pressure values are measured by a Pitot$-$static probe in the test section of a wind tunnel to obtain the freestream velocity. The measured voltages and the calibration equation of the differential pressure transducer connected to the Pitot$-$static probe are given below. Apply Chauvenet's criterion and find out if there are any data to be eliminated; then find out the mean velocity in the test section.
