A fluid dynamics simulation is run on a pipe system. Which effect results when the Reynolds number significantly exceeds the critical value?

💡 Explanation

Turbulence occurs because above the critical Reynolds number, inertial forces overwhelm viscous forces, leading to chaotic flow. Therefore, increased turbulence results in greater mixing and drag, rather than laminar flow or a linear pressure drop.
