Which outcome occurs when a gas pipeline suddenly constricts?

💡 Explanation

Increased flow turbulence results, because the vena contracta effect causes increased velocity locally; laminar flow transitions to turbulent due to exceeding a critical Reynolds number therefore increased turbulence, rather than smoother flow implied by other options and specific gas mixture.
