A thermocouple placed in the mouth of a pitot tube can be used to measure

A thermocouple placed in the mouth of a pitot tube can be used to measure the stagnation temperature of a flow. Such an arrangement placed in an air flow gives the stagnation pressure as 180 kPa, the static pressure as 55 kPa, and the stagnation temperature as 95°C. Estimate the velocity of the stream assuming that the flow is supersonic.
