A simplified model of how an airplane flies relies on a difference in air pressure between the top and the bottom of the wing. If a Boeing 737 has a mass of 29,000 kg and a total wing span area of 100 m2, what difference in pressure (in N/m2) is necessary for the airplane to maintain altitude? part b: in contrast, calculate the pressure difference (in N/m2) necessary for a 109 g Sharp-shinned hawk with a wing area of 0.0439 m2 to main altitude.
