What is y-junction?

A y-junction is a type of branching junction where a single, incoming pipeline or conduit divides into two branches that diverge from each other at an angle, forming a "Y" shape. Y-junctions are commonly used in plumbing, electrical wiring, and fluid transportation systems to split flows of substances, such as water, gases, or electricity, in different directions.

In fluid mechanics, Y-junctions can influence the flow rate, pressure, and direction of the fluid streams, creating turbulence and possible blockages at the junction. Therefore, engineers must design y-junctions with appropriate shapes and angles to ensure a smooth and efficient flow of fluids through the system. Additionally, y-junctions can also be used to combine two streams of fluids into one, known as a "confluence" or "merging" junction.
