Homework Statement
Find the lift in Newtons due to the Bernoulli Principle on a wing of a plane of area 84.5 m^2 if the air passes over the top and the bottom surfaces at speeds of 347m/s and 289 m/s
Homework Equations
P1+(1/2)densityV^2 =P2+(1/2)densityV^2
The Attempt at a Solution
Ok so i know the density of air is 1.29kg/m^3
so i plug into equation to get
1/2(1.29kg/m^3)(347m/s)^2= 1/2(1.29kg/m^3)(289m/s)^2
then i get answer of 5.39x10^4 N/m^2
then i use equation F=PA
and P is 5.39x10^4 N/m^2 and A is 84.5m^2
to get answer of 4.6x10^6 N
Am i correct ?
