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.
