Question: An airplane uses a pitot-static tube as a velocimeter. The measurements, with their uncertainties, are a static temperature of (11 3)C, a static pressure

An airplane uses a pitot-static tube as a velocimeter. The measurements, with their uncertainties, are a static temperature of (−11 ± 3)°C, a static pressure of 60 ± 2 kPa, and a pressure difference (po − ps) = 3200 ± 60 Pa. (a) Estimate the airplane’s velocity and its uncertainty. (b) Is a compressibility correction needed?
