key term - Bernoulli

Definition

Bernoulli's principle is a fundamental concept in fluid dynamics that describes the relationship between the pressure, velocity, and elevation in a flowing fluid. It states that as the speed of a fluid increases, the pressure within the fluid decreases, and vice versa.
