Answer:
4523.17365 Pa
Explanation:
m = Mass of plane = 77000 kg
F = Force = Weight = [tex]mg[/tex]
g = Acceleration due to gravity = 9.81 m/s²
A = Total area of wings = 167 m²
The pressure difference would be
[tex]\Delta P=\dfrac{F}{A}\\\Rightarrow \Delta P=\dfrac{77000\times 9.81}{167}\\\Rightarrow \Delta P=4523.17365\ Pa[/tex]
The pressure difference required to keep the plane aloft is 4523.17365 Pa
