What does the Bernoulli Effect explain about fluid dynamics?

The Bernoulli Effect describes how the pressure within a fluid varies with its velocity. Specifically, it states that as the velocity of a fluid increases, the pressure within that fluid decreases, which correlates with the principle of conservation of energy. This principle can be illustrated using the concept of potential energy, where increases in flow speed are accompanied by a reduction in pressure energy and potential energy.

The reasoning behind the correct choice focuses on the relationship between pressure, velocity, and potential energy within a flowing fluid. As the flow of a fluid accelerates, the kinetic energy increases, and since energy must be conserved, the pressure energy must decrease. This results in a higher velocity being associated with lower pressure, clearly demonstrating how flow dynamics work according to the Bernoulli principle.

The other statements do not accurately reflect the principle. For instance, stating that high velocity results in high pressure contradicts the fundamental explanation provided by the Bernoulli principle. Additionally, the claim that fluid flow is not affected by pressure changes overlooks the critical interactions between pressure and flow that the Bernoulli Effect highlights. Lastly, the idea that fluid potential energy remains constant regardless of flow misrepresents the relationship outlined by Bernoulli's principle, which shows that potential energy adjusts as flow
