Question

airplane in flight has a pressure difference between the lower and upper wing surface; this provides an upward force that balances the weight of the plane. If a plane has a wing area of 167 m 2 and a fully loaded mass of 77000 kg, what pressure difference is required to keep the plane aloft?

Answer 1

4523.17365 Pa

Step-by-step explanation:

m = Mass of plane = 77000 kg

F = Force = Weight =
`mg`

g = Acceleration due to gravity = 9.81 m/s²

A = Total area of wings = 167 m²

The pressure difference would be

`\Delta P=(F)/(A)\\\Rightarrow \Delta P=(77000* 9.81)/(167)\\\Rightarrow \Delta P=4523.17365\ Pa`

The pressure difference required to keep the plane aloft is 4523.17365 Pa
