An airplane is flying at 300 mi/h at 4000 m standard altitude. as is typical, the air velocity relative to the upper surface of the wing, near its maximum thickness, is 26 percent higher than the plane’s velocity. using bernoulli’s equation, calculate the absolute pressure at this point on the wing. neglect elevation changes and compressibility.

57330.17766 Pa

Explanation:

= Pressure at 4000 m = 61660 Pa

= Density at 4000 m = 0.8194 kg/m³

(Values taken from table of properties of air)

= Velocity of jet =

= Velocity at max thickness

From Bernoulli's equation

The absolute pressure at this point on the wing is 57330.17766 Pa

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
