An aircraft is cruising at a speed of M = 0.77. The freestream temperature is 222.77 K, and ρ = 0.4097 kg/m^3.

The pressure is measured on a point along the wing, and it is found to be 9120 Pa.

Calculate the Cp for this point.

A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) a)At takeoff the aircraft travels at 63.0 m/s, so that the air speed relative to the bottom of the wing is 63.0 m/s. Given the sea level density of air to be 1.29 kg/m3, how fast (in m/s) must it...

At an altitude of 11000 m (a typical cruising altitude for a jet airliner), the air temperature is -54.0 ∘C and the air density is 0.410 kg/m3 . What is the pressure of the atmosphere at that altitude? (Note: The temperature at this altitude is not the same as at the surface of the earth, so the equation P=P0exp(−MgyRT) doesn't apply.)
