Question

Air moves through wing of aeroplane such that speed of air above and below is 60m / s and 40m / s if area of wing is 2m then lift force is?

Answer 1

Answer:

Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls upward around it.
