Quick Reference

A hydrodynamic effect due to the relationship between relative velocity and relative pressure, which acts on an object as it moves through a fluid. The pressure exerted on the object by the fluid decreases as the velocity of the fluid increases. Thus, regions of relative high velocity fluid flow are associated with regions of relative low pressure and conversely regions of relative low velocity fluid flow are associated with regions of relative high pressure. The Bernoulli effect acts on balls and other projectiles in flight. When a region of relative high pressure is created on the under surface of a projectile and a region of relative low pressure on the upper surface, the result is a lift force directed perpendicular to the projectile from the high pressure side to the low pressure side.
