Why airspeed measurement in supersonic flow are different than subsonic flow?

Airspeed measurement in supersonic flow is qualitatively different from the subsonic flow. In supersonic flow, a bow shock wave is formed ahead of the pitot tube. As a consequence, the total pressure measured at the nose of the pitot probe in supersonic flow will not be the same value as that associated with free stream pressure. That's why a separate shock wave theory is applied to relate pitot tube measurement to a free-stream Mach number

What is the use of Rayleigh pitot tube formula?

Rayleigh pitot formula relates the Pitot pressure (stagnation pressure downstream of normal shock) and the freestream static pressure, to the freestream Mach number. Therefore it is used to calculate the upstream flow Mach number when pitot pressure and free stream static pressure are known.
