Question

An airplane was flying horizontally at the altitude of 5000 m. An observer on the ground first heard the sound of the airplane when it was 12 km from the overhead position of the observer. Estimate the speed and Mach number of the airplane. The average temperature of air between the ground and the altitude of 5000 m is -10°C. Given that y = 1.4 and R = 287 J/kg K.

Step 1

4 * R is the specific gas constant for air, which is 287 J/kg K * T is the temperature in Kelvin, which is -10°C + 273.15 = 263.15 K Show more…
