text: First, overall lift is proportional to the circulation generated; second, the magnitude of the circulation must be such as to keep the velocity finite at the trailing edge in accordance with the Kutta condition.
text: Lift is proportional to the density of the air and approximately proportional to the square of the flow speed.
text: Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction.
