Air pressure and force of lift

Click For Summary
SUMMARY

The discussion centers on calculating lift force using Bernoulli's principle, specifically addressing the relationship between pressure difference and wing surface area. The formula for lift is confirmed as force = area × pressure. When given a pressure difference of 4% of atmospheric pressure, the pressure value used in the formula is 0.04 times the atmospheric pressure. This clarification is essential for accurately determining the lift generated by a wing.

PREREQUISITES
  • Understanding of Bernoulli's principle
  • Basic knowledge of pressure and force calculations
  • Familiarity with atmospheric pressure concepts
  • Ability to work with percentages in mathematical formulas
NEXT STEPS
  • Research the application of Bernoulli's principle in aerodynamics

I know about Bernoulli's principle and that a difference of pressure below and above a wing create lift, but I cannot find anywhere a formula or any information on how to find the amount of lift given the surface area of the wing and the difference in pressure as a percentage of atmospheric pressure...my book is not helpful at all.

I've found that force = area X pressure, which of course makes sense...but given that my problem gives me the difference of pressures below and above as 4% atmospheric pressure, is the pressure value in that formula .04?
