You will be measuring velocity with the Pitot tube. Assume that the air density is 1.18 ± 1 x 10-4 kg/m3 and that the pressure sensor measures a differential pressure of 29.4Pa ± 1.0% FS. (Sensor range 0-60 Pa) Determine the uncertainty in the velocity reading. (Hint: Calculate the expected velocity from the Pitot tube. Remember uncertainty theory when multiple variables are involved!)
