Calculating Lift Force Using Bernoulli's Principle
This detailed example demonstrates how to calculate the lift force generated by an airplane wing using Bernoulli's principle and the standard lift equation. With a wing area of 15 square meters, airspeed of 60 meters per second, air density of 1.2 kilograms per cubic meter, and a lift coefficient of 0.5, the step by step calculation shows how to substitute these values into the formula L = 0.5 × Cₗ × ρ × v² × A. The calculation proceeds through squaring the velocity to 3600 square meters per second squared, then multiplying through the coefficients to arrive at a final lift force of 16,200 Newtons, which represents the upward force needed to overcome the aircraft's weight and maintain level flight.
