Pronunciation GB: bɜːˈnuːli, GA: bɜrˈnuːli
A physical effect discovered by Daniel Bernoulli, a Swiss mathematician and physicist living in the 18th century. He observed that a fluid increases its velocity when flowing through a constriction in a passageway. The velocity increase causes a pressure drop at the constriction. The Bernoulli effect is essential for the maintenance of vocal fold vibration.
