Task 1.2 (4) A plane flies at 12 km height with

Task 1.2 (4) A plane flies at 12 km height with Mai = 0.95 (95% speed of sound). The temperature of the surrounding air is T1 = 217 K, the pressure is p = 0.03 MPa. What would be the Mach number Ma2 close to the surface (T2 = 290 K and p2 = 0.1 MPa), if the plane flies at the same speed? Air can be considered an ideal gas with a temperature independent isentropic exponent
