SUMMARY

The net upward force on an airplane wing with an area of 20 m², where air flows at 300 m/s over the top and 280 m/s underneath, can be calculated using Bernoulli's equation. The difference in airspeed creates a pressure differential, resulting in lift. Specifically, the lift force is derived from the equation: Lift = (Pressure_top - Pressure_bottom) * Area. Understanding this relationship is crucial for solving the problem accurately.

Homework Statement


What is the net upward force on an airplane wing of area 20 m2 if the speed of air flow is 300 m/s across the top and 280 m/s across the bottom.


Homework Equations





The Attempt at a Solution



I have a feeling that this is an easy question, but i just don't know how to solve it! Any hints would be greatly appreciated.

Hint: there is a lift force is because the pressure on the top and bottom surfaces of the wing are different.

What equations do you know that relate pressure in a fluid to the speed of flow?
 
So that would be Bernoulli's equation, right?
But how would you use that in this case?
