Posted: 28 Jul 2011 06:48 PM PDT

A hypersonic experimental aircraft is flying in the lower stratosphere at an altitude of 20 km, at a ground speed of 177m/s.
a)the atmospheric pressure and temperature experienced by the aircraft at 20 km altitude, assuming an isothermal variation in temperature in the stratosphere,calculate
b)the Mach number at which the aircraft is flying.
c)the Mach number behind the shock wave located just ahead of the aircraft nose.
d)the temperature and pressure experienced by the tip of the aircraft nose.
