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 of 60 ± 2 kPa,
and a pressure difference (po 2 ps) = 3200 ± 60 Pa.
(a) Estimate the airplane’s velocity and its uncertainty.
(b) Is a compressibility correction needed?
