What is convergent divergent mouthpiece discuss the discharge through convergent and divergent mouthpiece?

Answer 1

A convergent-divergent mouthpiece, often used in fluid dynamics, is designed to control the flow of fluids, typically in applications such as nozzles. The convergent section decreases the cross-sectional area, accelerating the fluid and increasing its velocity, while the divergent section allows the fluid to expand and decelerate. In a convergent mouthpiece, the discharge velocity increases as fluid pressure decreases; conversely, in a divergent mouthpiece, the discharge velocity stabilizes or decreases as the fluid exits, distributing the flow more evenly. This design is crucial for optimizing flow efficiency and performance in various engineering applications.
