The relationship between flow, velocity, and pressure can be explained using Bernoulli’s principle. Bernoulli’s equation states mathematically that if a fluid is flowing through a tube and the tube diameter decreases, then the velocity of the fluid increases, the pressure decreases, and the mass flow (and therefore volumetric flow) remains constant so long as the air density is constant. ### fluid dynamics - Relation between water flow and
