At an altitude of 11,000 m (a typical cruising altitude for a jet airliner),the air temperature is -56.5C and the air density is 0.364 kg/m3.What is the pressure of the atmosphere at that altitude? (Note: The temperatureat this altitude is not the same as at the surface of the earth, so thecalculation of Example 18.4 in Section 18.1 doesn’t apply.)
