1.A jet flies at altitude 6 km. A pitot tube on the wing tip reads Po = 72 kPa . (a) what is the jet's speed and Mach number? ; (b) what is the stagnation temperature at the pitot tube ? ; (c) if the jet's speed is tripled (x3) what Po would the pitot tube read? Approx. Ans: (a) V ~ 200 m/s ; M~0.6 ; (b) To~ 240K ; (c) Po~ 300 kPa
