Question

The air pressure on the bottom of an airplane’s two wings is greater than the pressure on the top, providing an upward lift. Calculate the surface area of one wing required to lift a plane weighing 4.00 x 105 N if the pressure difference is 0.100 atm.

Answer 1

P=F/A

A=F/P

P = 0.1 atm = 10132.5 Pa

A=4 x 10⁵/10132.5

A=39.477 m²

for one wing=39.477 : 2 = 19.739 m²
