Let us apply Bernoulli's equation for upper and lower part of air plane.
 
begin mathsize 12px style p subscript 1 space plus space 1 half rho v subscript 1 superscript 2 space equals space p subscript 2 plus space 1 half rho v subscript 2 superscript 2 end style
let suffix 1 indicates condition of upper part and suffix 2 indicates condition of lower part
 
begin mathsize 12px style p subscript 2 space minus space p subscript 1 space equals space 1 half rho cross times open parentheses v subscript 1 superscript 2 space minus space v subscript 2 superscript 2 close parentheses space equals space 1 half cross times 1.3 cross times open parentheses 120 squared space minus space 90 squared close parentheses space equals 1 half cross times 1.3 cross times 210 cross times 30 space equals space 4095 space N divided by m squared
end style
gross lift = 4095×10×2 = 81900 N
