Given that  Speed of air at bottom is v1 = 114 m/s
  the speed of air at top is v2 = 107 m/s
------------------------------------------------------
Bernoulli's equation ,
       P1 + (1/2)?
v12 + ?gh = P2 + (1/2)?
v22 + ?gh
       ?P = (1/2)?
v22 -Â Â (1/2)?
v12
            Â
= (1/2)?(v22 - v12)
              =
(1/2)(1.29 kg/m3)(114^2m/s2 -
107^2m/s2 )
            Â
= 997.815 Pa
              =
0.997 kPa
(b) Upward force exerted on the wing is
            Â
F = ?P*A
               Â
= (997.815 Pa)(32 m2)
               Â
= 31930.08 N
                 =
31.93 kN
