Which outcome occurs when a fluid encounters a sudden pipe expansion?

💡 Explanation

Increased turbulence and energy dissipation occur, because the rapid geometry change drives a flow separation behind the expansion step causing increased Eddy viscosity. Therefore momentum mixing increases, rather than laminar flow which requires gradual transitions.
