Bernoulli's Principle Predicts

Question

Bernoulli's principle predicts
A) That pressure varies inversely with flow velocity
B) That velocity varies with cross-sectional area
C) That pressure near an object increases as water velocity increases
D) That small objects sink at constant velocity

Accepted Answer

According to Bernoulli's principle, in a streamline flow, an increase in the velocity of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. Thus, pressure varies inversely with flow velocity.
