Homework Help: Physics

Posted by Jay on Thursday, December 8, 2011 at 10:05pm.

An airplane wing is designed so that the speed of the air across the top of the wing is 274 m/s when the speed of the air below the wing is 193 m/s. The density of the air is 1.29 kg/m3. What is the lifting force on a wing of area 25.0 m2?

I know that it is the pressure difference times the area of the wing.

I know I need to use Bernoulli's equation but I do not know how incorporate area into it.
